My main aim is to do some rust repairs in my car..
With car sheet metal you don't generally use an arc welder as too much heat will distort the panel so yes it could be done but is slow.
In my opinion Tig is best ,then Mig then oxy ,then LPG brazing and last is arc welding.
If it's not a structural repair on the car and is just a panel repair the easiest and cheapest way would be gasless mig
or LPG Brazing.
