If it were me...

I would hit the local home supply store's electrical aisle for a replacement
stove or dryer cord that fits the wall outlet. Both are at least 30 amp
rated and a lot better than what you have.

Thanks for the advice Mike. From what I can see from the specs, the
welder draws 40 amps at max power. It looks like the power cord is
probably 14 gauge.


All the 14-gauge 3-conductor service cords I see listed are only rated for
18A. Grant's point was that the cord is sized for 40% duty cycle (40A
times 40% = 16A average current). But the heat generated in the cord is a
function of the current squared, so if you put through double the current
you're creating 4 times the heat. That gives you 4 times as much heat 40%
of the time, and no heat 60% of the time, which is equivalent to 1.6 times
as much heat all the time. If it were me I'd rewire it with at least a
10-gauge SOOW cord (30A, oil resistant, outdoor rated).
