Bit of a black art ally welding by any method. As John says it drops into a puddle if you look at it too hard.
I used to have a mate who could gas weld it. He put a patch in a vintage racing car bonnet where a non-standard blower had been fitted, and when it was cleaned up, you couldn't see where the repair was.
I was impressed!
good one . In fact the one I still remember was previous to that and with oxy acetelene. a blob of metal went down my boot and cauterized itself into my ankle - I was at a welding bench practicing @ tech.
I always love the way that no matter how you think you have filled all the gaps in the kit you're wearing, a spark will get in somewhere, and bounce all the way down to your boots where it burns you! Always funny to see someone learning as they jump about. Once you've had it happen a couple of times you realise that there's nothing you can do about it!
Back to the OP. The more you spend on a welder, (in general) the greater the power, and the more versatile it will be.
I looked at the cheaper sets to start off with, and ended up paying quite a bit more. That's life though.
One definite tip which has nothing to do with the machine, is to get everything as clean as possible and back to bare metal. As I said earlier, get new steel sheet the right thickness for the job. Practice first until you can run a weld. It all makes it much easier to get right.
