Connecting wc1 to millermatic 250

[Mcwelding1]

I just bought a wc1 controller with spoolmatic gun and an having trouble figuring out how to connect the control box to my mm250. Cant quite figure out how to wire in the 115v contactors. The welder does not have the spool gun module and if it's easier I also have a l-tec migmaster 250 that it could be connected to. Any help would be great, thanks!

Which model spoolmatic..??

Have you checked the hookup chart...???

You may not need the WC-1.... it may be direct connect (with the 10-Pin Module #043084)

Its a an old spoolmatic 1 so I believe I do need the control box? Also I don't have the spoil gun module on the front anyways. Just tryna get by on the cheap!

That would do the trick, your saying it probably isn't worth the time trying to rig up the control box than?

Depends on if it is more cost effective for you weld chargeable hours .... or if adapting to save a few bucks is a better solution..for your situation...??

do you make more money welding or tinkering .....???

Once it is set up there shouldn't be much trouble though correct? Not tyring to be a pain in the ass but id much rather just use the control box that I already have than to drop more money on it.

This should be your manual..............

Seems to me that if you disconnected the jumpers at #2 and #3, (CR1) you could run separate trigger wires to that CR1 at the same places you took the other ones off of. To the machines trigger ( where the existing mig gun plugs into. So you would need a simular connector like the mig has.. Plug the WC-1 in the wall, and hook up its arc cable to the positive on the feeder, then merely flip the drive wheels open on the feeder when you want to run the spool gun.

Clever... common sense solution.....................

So I did this and all was going good until I tried hooking up the trigger. Something went pop and now my 250 wont feed wire or start an arc with the trigger. ;It does turn on but I have no clue what's wrong. Blew something up I guess

Kinda think I back fed 115v through the two pin trigger on the welder.

OUCH..!!!

coupla wires crossed....???

Cause you didnt disconnect the wires off CR!, the idea here was to dry connect the new wires to CR1, Thought that was clear. Guess not. A simple looksee at the diagram would have told you what to do.
