Does anyone know if Shielded Inert Gas Metal Arc is an alternative name for MIG welding. I have a S.I.G.M.A control switch and 3 pin twist outlet connected to a separate internal contactor coil on my P&H second generation style Union Carbide Linde Tig welder. I am hoping to use my welder constant current along with a Hobart (Miller) 60 series wire feeder constant voltage only. I have no manual, I do have a partial circuit diagram with one corner section missing for the welder, what I can read shows the 24volt supply for the control circuit and an auxiliary reactor coil? Is this auxiliary reactor coil used to give a constant voltage in SIGMA control. This welder was probably built in the 60s but still works with stick and TIG. I purchased it recently and I am still in learning mode with the unit.
