i recently acquire a nice spot welder and both wands use 4/0 wire but they need some touch up due to loosening on the machine and the wands, the image shows how the machine end looks like and i'm looking for some kind of connector that i can solder or press to attach

i searched a bunch of welding supplies but they don't have anything for that large of wire

 

The pic looks like they took copper pipe, cut it to length, crushed it onto the cable, then drilled a hole in it. There's a tutorial on here for that - just buy the appropriate tube diameter.

You can get copper lugs at Lowes or Home Depot. You can also find them at Sayal Electronics on Matheson/Dixie.

I was checking out the sizes at Lowes on saturday and they had up to 2/0.

Look for them in the hardware section, should be in the little drawers

 

lol never knew lowes carried that size, largest wire hardware i've seen at the big box stores is 4 ga
