There's a picture in the manual about how to ground everything to try to minimize interference, but the easy fix might be to turn off the sprinkler system (either power or water) when welding...

Connect the green wire in the power cord to ground on your plug, which will often have green paint or a green screw, or be labeled G. Connect the black wire to one of the hots on your plug. Connect the white wire to the other hot on your plug. Doesn't matter which goes to which. Both of those should...

Can you inspect it to make sure it hasn't been gutted? If it has been gutted, stay away from it.

Repairs can range from about $5 to $5000... However, a broken but complete machine is always worth a couple hundred. Heck, if you get it for $50, and it's complete, I'll give you $150. ...

[Bushytails]

It might be worth that to the right person, but it's well outside my definition of really cheap.

[Bushytails]

For accessories, I've had excellent luck with weldingcity, if you want to save money. The products are all chinese, but they seem to pick acceptable quality stuff to sell.

Alas, a coolmate 3 is very overkill for my 200A welder, unless you want to get rid of it really cheap...

X-rays and various other scanners that intentionally aim EM radiation at people come to mind...

[Bushytails]

The machine itself doesn't actually need any conversion. The only thing you need to do is swap on the correct plug onto the power cord, wired correctly....

[Bushytails]

Just some generic advice... Now might not be a great time to start a business, unless it's making toilet paper! If you can, start your welding business on weekends or days off, to make sure it's picking up before you quit your main source of income.

The xmt350 will run fine on either single phase or three phase. Instructions for how to connect a single phase plug are in the owner's manual, which you can get under "support" from the top menu on miller's site. It should run off a generator of that size, but you won't be able to use its...

If it turned off, made bad noises, and emitted smoke, then I would wager that, yes, it's broken.

The XMT304 is quite repairable, unlike the newer XMT350 and such. First thing to do, if you want to repair it yourself or just get an idea of what it'll need, is pop the cover and look...

The arc reach power sources still have a 14-pin connector, and all 14-pin accessories should work on them, including wire feeders. The converse is also true - if you get an arc reach feeder, you can use it with non-arc-reach power sources, and it will work just like any other vs feeder. I don't think...

[Bushytails]

I'd suggest starting by figuring out what's wrong, repairing it, and then putting it back together.

I'm not familiar with any part called a "lift injector"......

[Bushytails]

They're expensive because they know you have to get one no matter what they charge you for it......

[Bushytails]

Looking closer, it's on the stator, not the rotor. That's not quite as bad, but that's still somewhere I really don't want to see splices on a unit suspected to have burnt windings.

The larger the pictures the better. We're not there and can't look closer at things just by moving our...

[Bushytails]

Those don't look obviously bad, but it's hard to tell with how small your photo is.

Is there "custom" wiring on the rotor, at the top of the photo?...

[Bushytails]

Next step is to check for voltage at the slip rings.

[Bushytails]

I'd say it's value running and welding is about $600-$700, but that's here, not where you are.

If you don't have it yet, your manual should be https://www.millerwelds.com/files/ow...s/O423_MIL.pdf

Trying to weld in power mode is unlikely to damage the unit, but that...

I'm a 42, somewhere between A and B... Oh, wait, that's not what you're asking about!

My understanding is you only need large cups for stainless and titanium, and you'd do fine with a #4 cup on mild steel with a .040 tungsten, so a #12 would indeed by way overkill. Does your application...

[Bushytails]

Have you checked your spark plugs, plug wires, and valve lash adjustment?

It's probably a bad regulator, but it's worth checking the common maintenance items first, since they can also do that, especially overly tight valves....

[Bushytails]

I would figure that's close enough, and look for the problem elsewhere.
