Kalas UtiliFlex™ 90°C Non-Shielded Jumper Cable

We pride ourselves in being the manufacturer of the industry’s best cable in several markets. We manufacture the industry’s leading welding cable,  ToughFlex and the ultra flexible orange FlexWhip™, among many others. Now we add to the family of reliable industry leading cables: UtiliFlex™  90° Non-Shielded Jumper Cable.

What Makes Kalas Able to Create Superior Cable? 

What makes our cable more reliable and preferred than the competition? Several factors come into play. Here at Kalas, we have a history of over 60 years in copper wire & cable manufacturing, which has given us the opportunity to refine and perfect our cable for higher quality. We draw our own copper for superior material control and our vigorous testing regimens we put all products through create wire & cable that customers can rely on. 

What Makes UtiliFlex™ Superior Jumper Cable? 

Specific to  UtiliFlex™  it meets ASTM F2321 standards having Flexible and Rigid Insulated Temporary By-Pass Jumpers. The Jumper Cable Jacket is EPR CV-cured and tested to prove resistance to abrasion, heat, moisture, and O-zone. The annealed copper stranding is extra flexible, making this cable easier to work with on the job than other cables on the market.  Its temperature performance is rated from -60C to 105C per NEMA WC71 and is water resistant. All testing is done 3rd party so you can trust the quality and durability when in use.

UtiliFlex™ Construction

To dig a bit deeper in to the construction of Kalas UtiliFlex™, its conductor is annealed Flexible Bare Copper per ASTM B3 & ASTM B172 or Tinned Copper per ASTM B33 & ASTM B172. The separator is semi-conductive tape separator between the copper and EPR Insulation. The insulation is Thermoset Ethylene-Propylene Rubber (EPR) as outlined in ANSI/NEMA WC-71.

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.  


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. Each cable is sequentially marked with the option to customize the print legend and even use PermaPrint™ indent print which will not wear off. We offer custom packing of all welding cable giving you the option to purchase cable coiled, boxed, or shrink-wrapped in 25, 50, or 100 ft. Lengths. And one of the things that makes us unique is we also offer fully finished assemblies. You can order FlexWhip in the unique configuration your work requires with Lenco & Tweco connectors creating the custom ultra-flexible welding lead you are looking for. 


We hope that reading through this helps you understand the difference between FlexWhip and ToughFlex while also revealing several reasons why FlexWhip rises to the top when it comes to selecting an extremely flexible whip cable.

Industry’s Best Welding Cable

We know it’s a tall claim – claiming our ToughFlex™ welding cable is the industry best. We stand behind that statement. By the end of this article we are confident you will too.

What Makes a Welding Cable Quality?

When it comes to welding, there are many critical qualities important for choosing the best welding cable for your job. Here we cover the top components of a quality welding cable:


Your cable needs to be durable. If not, you are looking at serious hazards. ToughFlex™ cable is jacketed with EPDM that resists cuts, tears, abrasion, grease, oil, water, and flame – tested to prove its long-lasting durability.


If you don’t know your welding cable’s safety ratings, you put end-users of the cable at risk. ToughFlex™ is rated to meet National Electrical Code Article 630 electric welders with operational temperature ranges from -40C to 105C. Meets UL VW-1 flame test as outlined in UL1581.


Once you have durability & safety covered, then you want the benefits of high conductivity. ToughFlex™ is manufactured with high-quality annealed 30-gauge bare copper conductor – making its conductivity top-notch!


Along with excellent conductivity, you don’t want to sacrifice ease of use. ToughFlex™ comes with both exceptional conductivity and high flexibility. A combination of our copper stranding and EPDM jacket allows superior flexibility above other welding cables.

What Makes ToughFlex™ The Industry’s Best Welding Cable?

ToughFlex™ meets all the criteria above as we touched on already. This is why we believe it has continued to be the best-selling welding cable available and are confidient it will continue to do so.

ToughFlex™ is extremely durable. It is jacketed with an EPDM (Ethylene Propylene Diene Monomer). This synthetic rubber jacket excels in resistance allowing ToughFlex™ to prevent cuts, tears & abrasion and withstand grease, oil, water, and flame.

ToughFlex™ undergoes intense testing and analysis proving its safety for welding. ToughFlex™ is rated to 600 Volts, meets the National Electrical Code article 630 electric welders, and UL VW-1 flame test outlined in UL1581. Along with the extensive testing, Kalas’ has more than 60 years in manufacturing copper wire & cable, touting a history of expertise. Therefore we are able to put our customers’ minds at ease by knowing they are receiving a product manufactured by experts in the field.

One of the top reasons ToughFlex™ is the best welding cable is its conductor – our copper. It’s Annealed 30 (0.010) gauge bare copper conductor with class K stranding. We start with 5/16” copper rod and with our rod mill we are able to draw down the copper to a finished gauge ready for jacketing. This gives Kalas complete control of the quality, efficacy, and craftsmanship of each product. The fine Annealed 30 gauge (0.010) bare copper conductor makes ToughFlex™ extremely flexible and easy to work with, coil and store. At Kalas, we are proud of our manufacturing process and the complete control it offers to our customers.

Lastly, something Kalas offers through owning the manufacturing process of our cables – is options in lengths, colors, packaging, finishing, and more. So whether you are looking for bulk welding cable or a bulk order of welding cable leads and extensions, we offer that. ToughFlex™ comes in #6 – 250MCM and virtually endless possibilities of customization. We offer ToughFlex™ in the standard black along with Blue, Green, Red, and Yellow jacket colors. We stock 250 ft. and 500 ft. reels, making orders in those increments extremely easy to ship right out the door including cut lengths in 25’ increments.
