Check the earth clamp, make sure all the cables or in good condition and secured, if the unit is three phase, get an electrition the ensure all the phased are functioning. test the fuses with a meter, get back to me if all is OK

a mig welding unit of 100 amps is very low, you will require a small wire size, plus the contact tip, liner to suit, expect to get a maximum amperage of 70- 80 amps max, if the unit is Aluminium wound transformer then expect 6 months use, and the ampage will drop ,then its scrap, depending on the weather conditions that the unit is kept, will depend on the live of the unit.

The mig welder should be capable of welding aluminum not stainless but the makers should be able to give you more detail. mig is used for steel and aluminum normaly but I do not know this transformer

Probably the trigger/ open the lead and try to short the connections for the trigger by bypassing the trigger acuator. This is the mechanism that activates the wire feed motor and applies the welding voltage to the wire. If this works, get a new torch handle.

There can be a switch that makes the wire electrically "dead" so it can be fed through the liner. Also suitcase style welders have a sensor wire with a clamp that must be connected for the arc to be able to be struck.
