Ultra-Flex #1 Welding Cable – 250 ft. Reel
This Ultra-Flex #1 welding cable comes on a full 250 ft. reel, giving you plenty of length for extension leads, whip leads, or wiring up a machine from scratch without running short partway through.
#1 gauge hits a good middle ground — enough copper to handle solid amperage without the bulk that makes bigger cable a pain to route and coil. And true to the name, this cable stays flexible even when it’s cold out, so it won’t fight you every time you uncoil it. The jacket also stands up well to oil, cuts, and everyday abrasion, which matters if this cable’s going to see regular use on a shop floor or job site.
What you’re getting
- #1 gauge copper conductor – fine-strand copper that delivers reliable conductivity across a range of welding amperages
- Ultra-Flex jacket – stays pliable in cold weather and resists oil, cuts, and abrasion
- 250 ft. reel – a generous length that covers long runs and bigger jobs without splicing
- Long flex life – built to handle constant coiling and uncoiling without cracking or going stiff
Why it’s worth having on hand
Low-quality cable stiffens up and starts cracking sooner than you’d expect, especially with regular use. This one’s built to keep flexing and carrying current the same way it did on day one, so you’re not replacing it every few months.
Where it’s used
A solid fit for MIG, TIG, and stick welding setups, plasma cutters, and engine-driven welders. Works well alongside the used Lincoln or Miller welders in our inventory.
