Tig welding for sheet metal using a tig welders means that one can work on materials of 26 gauge.
Tig welding automotive sheet metal.
Tig welding sheet metal forget the larger 1 8 inch tungsten electrode and use a smaller one.
Ditch a 1 8 inch tungsten electrode for something much smaller like 1 16 inch tungsten.
Because it will have you a lot more control over the whole process and it is more forgiving in case you do anything wrong.
If using the finger switch on the tig welder i like to set the machine to a fixed 50 60 amps for sheet metal work.
Factors to consider before buying best welder for automotive.
The best two electrodes for welding auto body sheet metal is either ceriated tungsten or thoriated tungsten.
I use a 1 16 red electrode and either 030 or 035 tig filler rod.
Ceriated tungsten are preferred with thoriated tungsten as a second option.
Nevertheless the quality of the finished work produced by the tig welding is by far better than that produced by an mig welder.
With the pedal i m able to fluctuate the amperage to get exactly the size weld and penetration i need.
Using this process enables more than effective work on thin materials as it provides high precision and high quality work.
