Go buy an UGLYS book. That is a reference for electricians and electronics. There are too many variables with the question you ask for anyone to safely answer it here.

What is the rated max current draw of the welder?

20A = 12GA
30A = 10GA
40A = 8 GA

My credo
If it ain't broke...fix it before it does.
I would say bigger is better.

Better to have it and not need it than need it and not have it!

So you are plugging into a dryer outlet or a welder outlet?

Harbor Freight should sell the welder cords.
