The thin and short cord on my HTP MIG200 welder was proving inconvenient, so I got a longer, heavier gauge wire 3-conductor (10ga) cord to replace it with. Here are the innards of my welder:
and where the 220vAC power comes inside:
Noticeably thicker wire and conductors:
After wiring the new cord:
and of course, doing an electrical and gnd test! (sorry for being out of focus):
I hope to practice a few more beads tomorrow

Tomorrow, make a welding trolley.
Next week make a welding table.
Do the do. Good man.
PS I love the way you copyright your photos.

Looks good. Just a heads up, our welder manual at work specifically said not to tin (solder) the wires. Check your manual to be sure you are safe.

For screw terminals, this is probably why, thermal expansion:

So in theory the screw terminals could get loose with time. I will keep an eye on these just in case - thanks
