Question about Welding Tools

Open Question

I have a Matco welder Mat-MG185. As soon as I cut the power on gas flows out of the gun. It has a Nu Tec gun on it. Some people telling me to replace the gun, other says it's a gas valve inside the machine. Could you help.

Why does wire keep coming out when trigger is not pulled


From the mig welder, unplug the trigger leads that exit the mig gun on the end of the gun that connects to the mig welder and power on your machine. If the wire flow stops, you have a shorted trigger circuit inside of the gun cable. If it doesn't stop wire flow, depending on your machine make & model, there is an internal issue with the trigger circuit that could possibly be just a simple relay issue.

I have a hobart 135 handler that with machine plugged in and turned on the wire has constant juice and the gas cylonoid is flowing gas from the bottle without the trigger being pressed. my dealer said it...


Hi:
Have you disconnect the gun's power plug? If the wire and gas stop flowing by doing this action, then your problem is the gun's trigger. If the machine continues to feed gas and wire with the gun disconnected then yes, it is the pc board.
Good luck.

My magnum 100l is flowing gas even when the power is off. How do I get it apart to look inside?


Hi:

Your gun is not the problem, your problem is the solenoid valve on your machine (welder) that solenoid valve must got dirt or debri from the hose and the closing needle it's stuck . Just replace it, it will be cheaper than replacing your gun.
Have a great day.

I suddenly am not getting any gas flow why ?


Could be many reasons there;

1) Ran out of gas pressure from cylinder. Replace cylinder.
2) Solenoid valve not opening or clogged. Replace solenoid valve.
3) regulator closed or faulty. Open regulator to adjust flow. or replace it.
4) Gun connector not pushed all way in.
5) Gun liner's gasket (o'ring) at end of gun missing or broken.

Lincoln power mig 200 .Wirw feeds and gas flows when power is turned on. Trigger switch is removed


Cables or lines at gun's switch end are touching or shorting out. Diconnect the gun from the plug/connector. If it persist then you have a bridged connector. Time to send it back for maintenance.
