Hi:

Gas light goes on when you have an air flow or pressure problem. Do you have enough pressure? you will need at least 120 psi at the compressor and 75psi at the plasma machine. Do you have enough flow? You will need 20 SCFH and a 30 gallon compressor reserve tank.

Let me know if this help. Please vote.

when mine act like that I check the tip make sure the air pressure is right and that it has a good ground

There is a resettable breaker inside the machine that cuts off power to the plasmahead when tripped. Check that and make sure the head is secore to cable and cable is secure to machine.

If it still fails to function check the coil in the contactor to make sure it has not burned out. Also check the pressure switch to make sure it closes contacts to make the circuit when the unit is pressurized If switch is not functional the head will not operate. Also check gas solenoid or solenoids to make sure they do not have burned out coils as well. An Ohmmeter should show about 2000 ohms give or take some. The main contactor winding also. It may be the main contactor needs replacement- a loose power connection can lead to burned contacts. So if you hear the machine click when you press the trigger, but no power to head, and all the other items mentioned still leaves you with no power at the head, that main contactor is the likely culprit.

If IGBT's had failed- they would blow apart part of their plastic case.So a quick visual is usually adequate for those.

A micro welding torch should be a smaller version of a full size welding torch - identical apart from size. It is most important a user thoroughly familiarises himself or herself with the correct usage and safety precautions because failure to observe the correct procedure can result in extreme danger. A flashback can have potentially serious consequences...

A person who is thoroughly conversant with the procedure and safety will know how to connect the hoses to the welding torch and to the cylinders - if it is a quality unit, it is an intuitive process due to the fuel gas fittings being left hand thread and the oxygen normal or right hand thread and the hoses are or should be different colours with blue being the norm for oxygen and red or orange for the fuel gas.

One final word - never, ever, under any circumstances use a lubricant on the threads of the oxygen bottle or associated fittings...

A great many older home mig welders were produced with a live torch, ie. the manufacturer had saved the cost of the contactor, the high current electromechanical relay that switches the welding current on or off in response to the torch trigger...

It was inevitable some manufacturers would replace the rectifiers and contactor with thyristors (SCRs) and obtain both functions from a single modification.

The trigger switch controls the wire motor and the contactor so if the wire motor is working ok it is unlikely the fault is there and if your welder has a contactor it could be stuck or a wiring fault has caused the coil to be permanently energised or if your welder uses the solid state version, either one or more of the thyristors have failed or a circuit fault has caused the supply to the gate to be permanent causing them to be permanently switched on.
