Welding Methods for Chassis

[baz-r]

here is how i see it yes the chassis could be sticked up by arc and there is no reason why not but note there would be meny positonal welds that would be tricky for a novice
a mig could equaly be used easy in practice

if you want to go down the stick/arc route a 150a dc inverter would be your best bet with a quality positonal rod. much more than 120 and you will be pushed for a 13a supply if you go for a transformer type set

if you go for mig then mixed gas with a .8 good qulaty wire and a mig 130-180a with the best duty cycle you can find in your budget have a look round for a s/h one
