O.K. So I go down to a local welding shop to see if maybe they have some old cables laying around that they would sell me cheap. They didn't, but I talked to the guy and he said I needed atleast 1/0 wire and they used the c-clamp type ground clamps. I thanked him for the info. I'm not going to be welding on the Golden Gate bridge anytime soon. Do I really need this heavy duty stuff? Honestly, I paid 100 bucks for the 225 Weldanpower, and I really don't know at this point if this thing will not eat itself, so I don't want to sink a whole lot of money into it until I can see some results. I used #4 jumper cables just to test it and it did strike and maintain an arc. I did it by feel because I don't even have a helmet so I couldn't look directly at it. I think you can understand where I'm going with this. That's why I was looking at the HF stuff. What's the minimum wire size I can get away with? 25 feet at the most is all I need. That's why I wanted a portable welder. Take the welder to the work, not the other way around. Could I live for now with #1 or #2?
