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.
