Question about Century Welding Tools

1 Answer

I have a century mod 11705093 wire welder. I have replaced the trigger switch. Even before this though, when you pull the trigger without wire in it the feed motor spins freely, when you put wire into it and pull the trigger, the feed motor is not spinning and the wire heats up and burns out where it enters the cable. Any solutions?

Hi there,

That sounds like a direct short short to me. My mig has 1 nylon guide tube,one in front of the feed wheel and one just before it inters the liner.They are both insulating the drive wheel from the wire.If the teeth marks are deep enough they will act like a saw and cut right through the nylon tubes and short out on something.You may need a new liner ,the liner is carrying the current instead of the wire.That may be problem. Thank You for choosing FixYa.com

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.

MIG welder 250 feeding wire at erratic speeds


Gun trigger contacts or switch circuit is closing somewhere (shorting). Unplug connector and jump the two terminals if it works and will weld disconnect jumper if problem persists it is not in the gun or cable hose. Keep chasing it far as possible without taking bolts or screws out of machine unless you know what that stuff inside will do to you, pretty sure the problem is not in there anyway.

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.

MIG wire is always hot without pulling trigger


Check your manual, there are a lot of mig units on the market that are alway "Live" alternatively, the relay has either shorted or you have wirering problem on the switch.
