Arcing before pulling the trigger

I have a Miller matic S-32S an older unit for sure, which I run through a Miller Thunderbolt power source. The problem is I get imediate arc as soon as I touch the wire to a piece of metal, without pulling the trigger. It will not let me start a weld this way, and as soon a it makes contact, the wire heats up to the tip. I have checked all the conections, and there are no frayed wire. The unit Thunderbolt unit arc weld nicely,so no problems with the power source. Any help would be appreciated. Ron

Phase three on cv or cc have current going to mig wire, wire is live without hitten gun trigger. mega arc is hooked up to a Hobart suitcase


May need to take gun apart and see if trigger is sticking or replace lead.

we use Miller at work. The feeder has a switch that makes the trigger turn off and on with quick pull of trigger so you don't have to hold it entire time.

check wiring to make sure it's wired right so your not bypassing the trigger switch.

hope it helps.

Miller 350p welder gives a "help 3" code.



Code help-3 Indicates that the gun trigger was pulled and held during power up. Release gun trigger and clear fault condition. Also, this display can Indicate no open circuit voltage detected when gun trigger is pulled and no arc detected within 3 seconds, this means that the trigger was held without any metal contact. The machine will shut down in order to avoit the wire to continue to run freely.

To fix:

Turn on the machine without pressing the trigger on the gun. Then increase to the max the wire speed. Then turn off the machine. Press the trigger after the machine was turn off, then without releasing the trigger, turn on the machine and release the trigger after 2 seconds. That will take care of it.

Spectrum 2050 plasma cutter . Cutter blows air and stops when trigger is pulled no pilot arc or any cutting when trig is released air flows again and stop after 10 sec new tips was working the day...


Check compressed air pressure is in limits otherwise unit will cut out. Try adjusting the pressure up. also make sure the supply pressure is correct as it may not be your plasma cutter at fault.

I have a miller thunderbolt 225v AC arc welder


The blank should be the grouDING conductor (green) and they may have a green screw to further indicate it.

Since the welder runs on 220, either of the hot wires can go to either of the other terminals (X or Y).. Those wires might be black, red, blue, brown.

There is a slight chance it would be white even though it is hot on the portable cord because some portable cord is used that way.

VERIFY the receptacle you connect to is wired correctely before connecting your unit to it.

Wire won't feed or arc fan runns


Look for a reset button on the case. Make sure that you have power to the machine and at the power socket. If everything looks ok outside, you may have to investigate your warranty. Good luck!

Millermatic 140 w/ auto set powers on but will not feed wire or arc


If its a new unit its probably nothing. Miller makes good stuff. Open the side so you can see the spool. With the machine on, press the trigger for a second. Did the little wheel spin (trying to feed the wire) if it did then your problem could be kinked wire, **** on tip, or spring on small spool is loose and wire is slipping. Let me know.
