A friend of mine has that same machine. It's an absolute beast on AC tig. Just sine wave AC but it has tons of power. I've seen some heavy aluminum he's welded with it. I asked him about duty cycle, but he said he's never overheated it that he knows of! I think he said he paid $350 for it years and years ago, and I thought THAT was a steal!

I won't have the welder here until my truck is out of the shop. I am installing a new engine, it should be done in a few days.

I am wondering about welding cable length. The MIG welders I have used have a ground cable that is shorter than the electrode cable. I suppose it is reasonable to assume that stick welders are the same? If so, what length would you fellows consider too long for such a welder running 1/0 cable welding 3/8" thickness? I am not averse to having two sets of cables. I could find some thicker, shorter cable at a reasonable price for heavier work when needed.

As long as the cables are heavy enough, it will not matter the length of each. But, with that said, the shorter you can have them, the better.

The length really depends on what you are welding. If you are always welding on parts on your bench, and the welder is next to you, then 10’ cables might be fine, but if you need to weld 100’ away from the welder because it does not move from the power source real easy, then consider that.

The biggest issue with the welding leads usually are the ends. Keep them clean and tight is the best. Especially if you use quick connects. Corrosion causes heat and limits the current quickly.

With heavy cables often a lighter ‘whip’ is nice for the electrode end. Usually 10-15’ of cable that makes it easier and lighter for welding.

I'll rephrase the question: When welding 3/8" structural steel, what is the longest run of 1/0 cable you fellows would use? I already have the cable but I want to leave it as long as possible for welding up on a second floor of a barn and such.

According to this chart 200+ feet I would think

You can always buy a couple more Tweco connectors and add or remove sections as needed...

As for using under sized wire you create a voltage drop which in-turn reduces amps, you may have to increase the machine output current on the dial maybe from 200 to 225 to get 200 at the weld.

as for long wires the smaller you go the hotter the cables will get, that would be ok if you let them cool off, I would guess with stick welding its unlikely you would be welding enough to have the cables run hot.

I would keep the cables as long as you can, if they get hot then consider thicker.. a short set is also good so you don't have to fight with long cables.


I'm just a hobbyist with welding

Lets add to your question

When "stick" welding heavy 3/8" steel assume I beam.
What rod would you use?
What size thickness rod?
What amperage setting?
How many passes?

I used to use a very light stinger lead and a five gal bucket of water for dipping

If you going to run 200' leads, I would go with 1/0 for the last 15'. Heavier on the lower end to reduce amp loss and too hot wires.
