I am looking for a remote pedal switch for my mm210. Basically it is a remote switch to activate the gun when depressed. I would be using this for a rotary jig welding application. Anyone know if they offer one for my machine?

I doubt Miller offers it, but why not get a foot switch and make your own? Thanks to ePay you should be able to accomplish the task for under $25-.

I will, if I can't buy one pre made.

would you suggest I find an inline socket to go between the cord and the machine? Or hack into the existing cord? How Much power goes through the trigger?

I would just add a connector in parallel with the original. The current is probably quite small. Any switch should work. :)

Yes, it seems to be just two wires, pretty small guage. Would most Miller dealers carry the factory connector ends?

Post the model & serial numbers, and I'll look at the diagrams on Miller's site for the answer.
The plug itself isn't unique to Miller.

The manual says that when replacing a switch in the gun, polarity is not an issue, so all I need is an interupt switch. I just need to know how many amps it needs to carry.

After looking at the schematic, all I'm seeing is a microswitch that triggers something on the PC board in the machine.
The switch in the gun is definitely a microswitch, and would have a max current capability of under 3 amps, though I doubt the relay or solid state device being triggered actually uses half an amp.
You could probably get by electricly with something like this

Let me know if you think it won't work. I'll splice it into the gun using spade connectors, so I can remove it and return the gun to normal use.

I'd be a little hesitant to use the RS pedal, especially since they really don't give any specs, to say nothing of the fact I've had to replace every damn thing I ever got from Radio shack.

In a welding environment you also probably want something that is metal and not plastic.
