In addition to what the others have said. I disconnect both battery cables and use a jumper cable to short them together. This prevents any voltage buildup.

<font color="red"> So long as you don't connect the welder right to the battery it won't be part of the circuit. There is no need to disconnect it. </font>
Hmmm. I kinda thought the same thing until i was watching a buddy of mine weld on his moterbike and the battery blewup. And he had the ground clamp connect right on the same piece of metal he was welding back on.

Why not fabricate what you need for the tractor off the tractor and then bolt the part on the tractor? That way it is easily removable.
Or is it an actual non-removable piece of the tractor?

I’d bet his battery blew up because a welding spark got in the hydrogen that was coming out of the battery… That is another thing to be aware of hydrogen plus welding spatter equals BOOM /forums/images/graemlins/shocked.gif. KennyV.

Yeah, it has to be that or something very similar.
I am not an EE but I have slept in some motel's so here goes... electricity moving in a conductor creates an external field which will induce electricity in an adjacent conductor, that's how transformers and some meters work. You with me so far? OK, so if you drag the weding cables over and around any wiring on the tractor you may be inducing voltage within the tractors wiring harness while you have an arc going, battery or no battery. Now, it's difficult for me to believe that welding cables properly routed could cause any problems. If the tractor has bits and pieces that are that sensitive they won't last anyway.
Given the proximity of fuel, plastic and battery gases then, yes, it's a good safe idea to weld off the tractor when possible. I wouldn't even bother to disconnect the battery on mine. In fact I think I will try it just to see what happens.
Later, I'm going back out to sleep at a motel to see if I'm correct.
All the Best,
Martin

Hey, EE here. Don't weld through a bearing or bushing, use common sense, and don't worry about disconnecting the battery. You should be fine. When I weld on my tractor I just try to ensure that the ground lead is attached directly to the piece that I am welding.
