Welding Cable Comparison: Kalas vs. Lower-Quality Alternatives

Kalas Welding Cable is engineered for safety, performance, and long-term reliability—while many lower-quality welding cables cut corners that can put both welders and equipment at risk.

When you are on the job site, your equipment is your lifeline. While the power source and the torch often get the most attention, the cable connecting them is just as critical. It carries the current, endures the heat, and takes the abuse of the shop floor.

Yet, not all welding cable is created equal.

In an effort to cut costs, many manufacturers have flooded the market with cables that look the same on the outside but cut dangerous corners on the inside. At Kalas Manufacturing, we believe that Kalas ToughFlex™ Welding Cable should be engineered for one thing: uncompromising safety and performance.

Here is the difference between a cable designed for the long haul and one that puts your equipment—and your team—at risk.

1. The Copper Standard: Meeting SAE J1127

The heart of any welding cable is the conductor. To save money, some lower-quality import cables reduce the amount of copper used, often falling short of the SAE J1127 standard. They may use a smaller gauge than advertised or lower-grade recycled copper.

The Kalas Difference: We strictly adhere to SAE J1127 standards. This means when you buy a 2/0 cable, you are getting the full copper content required to carry that current safely. Appropriate copper content ensures consistent ampacity, preventing the cable from overheating under load.

2. Flexibility is Safety (The Stranding Factor)

“Stiff” cable isn’t just annoying; it’s a hazard. Cheap cables often use “short-stranded” construction—meaning fewer, thicker strands of wire. This makes the cable rigid, hard to coil, and difficult to maneuver in tight spaces. Worse, short stranding creates internal stress points where wires can snap, leading to “hot spots” inside the jacket.

The Kalas Difference: Kalas ToughFlex™ is engineered with properly stranded, fully annealed copper. This high strand count provides maximum flexibility, allowing the cable to move with the welder, reducing wrist fatigue and improving ergonomic safety. Because the strands are fine and plentiful, they resist breakage even after thousands of flex cycles.

3. Surviving the Environment: Jacket Durability

Welding environments are brutal. Oil, grease, sparks, and abrasion are daily threats. Lower-quality cables often use inferior thermoplastic jackets that fail to pass rigorous flame resistance or elongation testing. These jackets can crack in cold weather or melt upon contact with hot surfaces, exposing the live conductor.

The Kalas Difference: Our cables are tested for durability, flame resistance, and elongation. We use premium jacket compounds designed for long service life in the most demanding environments. Whether it is being dragged across concrete or exposed to welding spatter, Kalas cable resists cracking and premature failure.

Head-to-Head: Kalas vs. The Rest

To make the choice clear, here is how our genuine American-made product stacks up against generic competitors.

Why Flexibility Matters in Welding and Power Cable

Maintaining Performance in Sub-Zero Temps

As temperatures drop across North America, industrial equipment faces its toughest test of the year. While engines and hydraulics often get the most attention during winterization, there is one critical component that is frequently overlooked until it fails: your cabling. 

Anyone who has tried to coil a standard garden hose in January knows that cold alters the physical properties of materials. In an industrial setting, a stiff, frozen cable isn’t just an annoyance—it’s a safety hazard and a productivity killer. 

At Kalas Manufacturing, we engineer our Welding and Power Cables to perform in the harshest environments. Here is why flexibility matters when the thermometer hits freezing, and what you should look for to ensure your job site stays powered up. 

The Science of the Freeze: PVC vs. EPDM 

Not all insulation is created equal. The most common reason cables fail in winter is the material composition of the jacket. 

Many standard commercial cables use lower-grade thermoplastics that become brittle as temperatures approach freezing (0°C / 32°F). When a worker tries to drag, bend, or coil these cables, the jacket can crack. A cracked jacket exposes the copper conductor to moisture, salt, and chemicals, leading to corrosion and immediate safety risks. 

To combat this, Kalas utilizes EPDM (Ethylene Propylene Diene Monomer) for our premium welding and industrial cables. EPDM is a synthetic rubber known for its outstanding heat, ozone, and weather resistance. 

The result? Our cables maintain flexibility and structural integrity in temperatures as low as -50°C (-58°F). 

Combatting Operator Fatigue 

Beyond the durability of the wire itself, cold-weather flexibility has a direct impact on your workforce. 

Welding and industrial maintenance require precision. If a welder is fighting against a stiff, frozen lead that won’t lay flat or bend around corners, two things happen: 

  1. Fatigue sets in faster: The physical strain of maneuvering heavy, rigid cable takes a toll on the operator’s wrist and arm. 
  1. Weld quality suffers: Precision movements become difficult, potentially leading to rework. 

Using a highly flexible, fully annealed copper cable with a high-grade EPDM jacket ensures that the tool moves with the operator, not against them. 

What to Look for in Your Winter Spec 

If you are procuring cable for outdoor construction, unheated warehouses, or utility repair work this winter, check the spec sheet for these three things: 

  • Temperature Rating: Ensure the cable is rated for at least -50°C. 
  • Stranding: Look for a high strand count (Class K or M). More fine strands of copper allow for tighter bends without kinking, regardless of the temperature. 
  • Jacket Material: Verify it is a thermoset rubber (like EPDM) rather than a standard thermoplastic. 

Stay Flexible with Kalas 

Winter is hard enough on your operations; your power connections shouldn’t make it harder. Whether you need reliable welding cable for the shop floor or heavy-duty power cords for the job site, Kalas Manufacturing delivers American-made solutions engineered to handle the cold.

The Most Flexible Welding Cable

We pride ourselves in being the manufacturer of the industry’s best welding cable, ToughFlex, and the reasons that cable continues to be the best-selling cable on the market. Many of those qualities overlap onto our other welding cables – such as how we draw our own copper for superior material control you can trust, having over 60 years of history in manufacturing cable to perfect our products for higher quality and our vigorous testing regimens we put all products through to create products you can thoroughly rely on. In this post, we want to share about our sister welding cable of ToughFlex – FlexWhip

FlexWhip is th most flexible welding cable on the market. Where our standard, ToughFlex is already extremely flexible, FlexWhip takes it even further.  Let us explain how.

What Makes FlexWhip™ Flexible? 

The major difference between ToughFlex and FlexWhip is that ThoughFlex is a 30 (0.010) gauge bare copper conductor whereas FlexWhip we draw down even finer to Class M stranding which is 34-gauge bare copper conductor. This extra drawing of the copper makes the cable even more flexible than its competition.  The design of FlexWhip welding cable provides superior flexibility which is helpful in giving you ultra flexibility when needed where leads, stingers/ whips, and grounds are used.  

Flexible, but also Durable? 

Our process of heating the copper rod and drawing it, allowing it to cool slowly, removes internal stresses and toughens it while also increasing its flexibility through how fine a gauge we make the copper strands. The result – a cable you can twist, bend, and move with ease because of its high flexibility that can equally withstand the harsh environments welding often requires.  

Safety is a big deal when it comes to selecting the welding cable you choose, and we take that seriously. We understand that the more flexible and fine the copper strand becomes, the more we need to assure the cable’s safety. There are serious safety issues if stranding is uneven, too thin, or prone to break, which definitely needs to be understood by the manufacturer you choose when buying a product like this from. That’s why we share with all of our customers the vigorous testing FlexWhip undergoes and the certifications it holds to assure its safety, reliability, and durability 

What Makes FlexWhip™ Better than the Competition? 

It took us years, but through vigorous testing and refining, we have created an ultra-flexible yet just as durable welding cable that touts unmatched reliability compared to the competition in the market. Combine that with our numerous customization options, Kalas’ 60+ year history of manufacturing, and our excellent customer service and you have a product that rises above the other options.  

Durability: 

Here’s what gives FlexWhip its sustained durability. First, it is insulated with a high-grade RoHS compliant EPDM (Ethylene Propylene Diene Monomer) jacket proven to resist cuts, tears, abrasion, grease, oil, water, and flame. It also has a paper separator to enhance stripability. FlexWhip™ has an operating temperatures range from -50°C to + 105°C, is rated to 600 Volts, and meets the National Electrical Code article 630 for electric welders and UL VW-1 flame test outlined in UL1581. We want to provide the fool-proof assurance you need when selecting the flexible welding cable you buy that you’ll receive a reliable product every time you buy FlexWhip. 

Customization & Options: 

We offer FlexWhip in gauges, #2 – 2/0, in the industry-standard orange jacket signifying flexible whip cableFlexWhip comes standard in 250 ft. and 500 ft. Reels, making those lengths easy to ship and get in-hands quickly while also offering custom lengths upon request.

Quality Characteristics of Kalas Flexible Cord

Flexible Cord – also known as Flexible Cable, high-flex or continuous flex cable, or Flex Cord is one of the less understood cables in our product catalog and can require a lot of technical knowledge to know which kind and what options to select. That could be because the use for Flex Cords is vast and the need for selecting the right type is high lest you run a safety hazardThat’s why we wanted to offer this article to provide some education about our Flexible Cord products and how Kalas is a superior choice to supply your flexible cord needs.  

What is Flexible Cord? 

To put it simply, flexible cords are often the cable used to take power from a source directly to its end-use application. Examples of that could be for use in lighting fixtures, small and large appliances, vacuum cleaners, and more. At Kalas, we manufacture three cables in our Flex Cord category – they are our Extra Hard Service Cord, which we understand is a deceiving title since “Extra-Hard” and “Flexible Cord” seem to be contradictions which we will explain, Hard Service Cord, and our SVT/SVTO cords. The reason the first two products listed have the word “Hard” in their title while technically being Flexible Cords, is that term signifies their jacketing is up to withstanding “hard” use. These two cords, our 600V Extra Hard Service Flexible Cord and our 300V Hard Service Cord, are supremely jacketed to safely distribute power and withstand the often-significant bend radius required when using or installing Flexible Cords. 

For example, think through a common service cord like one that plugs in a small appliance in your home – that cord may be used over and over, and you may bend it into a tight space to fit into your outlet. Therefore, it would be important that your cord is constructed safely enough that the copper stranding and insulation within it is built properly so it will not fray and will be able to stay as goodasnew over the life of the appliance. That’s what our hard” flexible Cords provide.  Below we will describe the unique qualities and variety of Flexible Cords we offer so you can better determine which would suit your application the best. 

Extra Hard Service 600 Volt PVC & TPE Flexible Cord 

First, we will talk through our Extra Hard Service 600 Volt PVC & TPE Flexible Cord. This cord is one of the products with the most selection when it comes to choosing your gauge and various options. That means with Kalas you can create the exact small or large enough cord to power and withstand the use your application reqiures.

We offer 18/2, 18/3 18/4, 18/5, 16/2, 16/3, 16/4, 14/2, 14/3, 14/4, 12/2, 12/3, 12/4, 10/2, 10/3, 10/4, 8/3, 8/4, 6/3, 6/4 , 6/3, 8/1, 4/3, 4/4 gauges and special stranding upon requestYou can also select bare or tinned copper as your conductor which can give you an option that is able to withstand corrosion or soldering to a higher degree. Lastly, we also offer our customers the option of jacketing with PVC (polyvinyl chlorideor a TPE (thermoplastic elastomermaterial which can give you a little more assurance of resistance to abrasion as well as chemicals. 

So depending on your use, you can create the exact 600 Volt Flexible Cord you’ll need. Each cord is insulated with PVC, meets the UL and CSA requirements for your selected construction so you can be confident in the quality, safety, and reliability of the cord you receiveWe can manufacture each cord to your liking to be ST, STO, STOO, STW, STOW, STOOW, SE, SEO, SEOO, SEW, SEOW, or SEOOW. We realize that’s a lot of information and can be confusing – all that to say, we are here for you, knowledgeable, and able to create the exact 600 Volt Flexible Service Cord you need. 

300 Volt Hard Service Cord 

Second, we would like to highlight our 300 Volt Hard Service Cord which is also available with your choice of a bare or tinned copper conductor and with PVC or TPE jacketing, insulated with PVC and constructed to meet UL & CSA requirements. This product we can manufacture for you in gauge 10-18 with 2, 3, or 4 conductors. The reason you would select this cord over our 600 Volt really depends on your job. We highly recommend viewing and understanding the NEC (National Electric Code) which goes into detail as to what cord you need, but typically our 300 Volt Flexible Service Cord is placed in small appliances like space heaters, electric fans, and similar small electric devices. The benefit of ordering flexible cord from Kalas, is that you get expertise and options. We can manufacture your cord to be SJT, SJTO, SJTOO, SJTW, SJTOW, SJTOOW, SJE, SJEO, SJEOO, SJEW, SJEOW, SJEOOW, SJT-R, SJTO-RSJTOO-R, SJTW-R, SJTOW-R or SJTOOW-R or 18/3, 16/3 and 14/3 fillerless cord – all of which will be manufactured with the same excellence that comes from our 60-year history in manufacturing copper wire & cable and our vast team of highly specialized engineers. Quality you receive when you buy from Kalas which other companies may not be able to.  

Both of our 600 V and 300 V Flexible Cords can be customized to have special stranding, non-wicking polypropylene, reinforced paper, or jute fillers and customizable inkjet print legend or PermaPrint™ indent print that will last the lifetime of the cable. Simply reach out and let us know what you need and we can make your cord a reality. 

SVT & SVTO Cords 

Lastly, we want to highlight our SVT & SVTO Cords. SVT stands for Service Vacuum Thermoplastic and SVTO stands for Service Vacuum Thermoplastic with Oil Resistant Jacketing. This cord is used in Vacuum Cleaners, Food processors, or Office Equipment for the most part. It comes with a bare copper conductor insulated and jacketed with PVC with an operating temperature of -40°C to 105°C.

You can order this cord in 18/2, 18/3, 17/3, 16/2, or 16/3 gauge all of which will be manufactured to meet the UL Standard 62 for Flexible Cord and CSA requirements give you the reliability and assurance you need to assure end-users of safety. The 18/2 and 18/3 gauges can be fillerless enhanced with a micro-poly strength member for mechanical strength. 

The composition of this cable provides excellence in durability because the conductors within are twisted with or without fillers. This twisting of the strands offers a tensile strength that can withstand high usage and bending – a perfect construction for something like a vacuum cord which needs to remain safe and reliable when frequently yanked and turned every which way! We also offer this with non-wicking polypropylene, reinforced paper, or jute fillers and custom print.  

Conclusion 

We hope this article has helped to increase your understanding of our Flexible Cord selection, why we call them “Hard Service Cords and helps anyone in the market for these types of cables to see the superior construction, customization, and support ordering from Kalas provides. We can handle any question you may have regarding our Flexible Cords and have highly attentive, informed, and educated customer service representatives that help make your experience of creating and ordering Flexible Cord from Kalas a positive experience.
