You can pull the rubber cover back and then loosen the set screw and remove the cable. That would save you a few bucks, because they run around $8.00 each. Sometimes you can get a good deal on cable at your LWS. I have also found good deals on cable through Amazon.com

That's probably because I mistyped. That should be 25. Sorry about that. It's actually a 9mm dia.

10-25mm2. I believe.

I'm thinking of adding some length to my cables as well and have a question along the same lines.

Using the calculator that Rambozo posted I figure 50' of 3 gauge will allow me 150 amps for my positive. That's clear. But how about the ground cable? Does it need to be the same? For you guys that've been doing this for a while, it might be obvious but I really don't know. I hafta go from my stove to shed to weld which is about 50'. Cable is expensive up here so I'd rather keep cost down by cutting the size a bit. Maybe even solder the joints to get better contact with the dinse connector, if it's possible.

For an extension cord and you only need to run the welder. And you need 3 wires for our single phase units.

Romex (NM), # 8 is good for 40 amps, # 6 is good for 50 amps. Do not run # 8 on a 50 amp breaker.

#8 THWN (dry) or THHN (wet) good for 50 amps, #8 ROMEX is only rated for 40 amps.

Get dual rated (THWN/THHN) #8 and you're good for 60' and 50amps.

Now that I think about it, you're right Mike. An extension cord is the best bet and leaving the leads at stock length. I was originally thinking of leaving the welder indoors at the house and welding outside 50' away but it'll probably be better off just bring the welder with me outside and run an extension cord. The ticker doesn't work so well at night. lol

I have some extra THHN #8 lying around from my last install but not nearly 50' of it, so I'll make due with that for now.

Yea, depending on the unit, take the unit to the work is not a bad idea. I do that with the MIGs and Plasma all the time. The 12' leads can be a challenge sometimes. I would just looking for a cheaper route for you on the cord.
