In the 1st vid the rods on the positive and the you tube vid its on the ground and he talks about that bin important,
Can anyone explain why it's important yet as shown in the 1st it worked the other way,
Electron flow if your using gas or gasless, to concentrate the heat on workpiece or filler.
If you get a ordinary mig on gas and swap polarities it doesnt work properly
I read this thread a week or so ago and though that's really useful to know, but never thought I would actually need it.
But yesterday, when out green laning with a few mates this happened to the gear stick on one of the vehicles
We had plenty of batteries between us, plenty of jump leads, but no welding rods!!! But you can be sure we will next time!!!
So after many phone calls, and a slowwww journey (he was stuck in 2nd gear) from one side of Dartmoor to the other, we arrived at an agricultural plant engineers yard where a friend of a friend was waiting to help us out
and he did a proper weld on the gear stick
But if only we had a welding rod (and a pair of welding goggles) with us, it would have saved us a couple of hours!!![]()
I think in the case where you have to think of everything a small set of oxyaccetylene would be better, easier to weld with and more useful!
I'll ask my son who is a marine how many battery welders he has used.
That seals it then. I'm carrying welding rods at all times. What gear were you stuck in?

Just mild steel isn't it so 6012 or something like that ?
Its more likely to be for thicker materials as opposed to sheet metal.
Things like trasmission and suspension I would guess are the most likely things to fail (which could be rewelded) and prevent you carrying on???
Wrap the rods in cling film as they absorb moisture and you'll get porous welds. Remember to take the cling film off before use though!all depends doc how thick the materials is and tensile strength is needed.
Better choice would be 6011 and 7014 in 3/32 dia rod, 6012 is shallow penetrating rod for sheet metal and those that do not know how to weed. covering a crack is not much good. 100% penetration is a good repair. If a solid material broke, what is a dab of weld going to do
