Voltage sense feeder? And SCORE!

That Cobramatic, it is made by lindie right?

Huh. A spool gun and a push-pull feeder. No wonder he is asking so much. Still I think he is quite high.

No, they're made by MK Products, I also think Lincoln is attached some how.

I think he's high also! No telling how old the equipment is, he may not even know. If you had the serial numbers Miller would know.

Hmm from the pictures I would have thought it was a lindie product, I guess not.

I think SA has a Linde feeder on top of the CM feeder.. All this is on top of a Linde? MP machine.

Ahh I guess I was looking at the linde feeder.

But here is my question. This is the wire feeder.

The wire feeder is a Voltage Sensing type. I get generally how that works (attach extra clamp to work and it picks up the contact from there). My question is what is the purpose or advantage of the Voltage Sensing style? Does it work better in certain applications? And which ones? I don't really need the portability of the suitcase welder, but since that is what it came with, so I'm going with it.

Oh - yes - it welds fine. There's a couple flux core beads in the middle right there. I was flying blind on settings at the moment, but I got it close enough to prove it works well. And a 3/32" 6013 above it to prove the stick function works well too. 0.045" Flux core was in the machine and I have no gas so I just used that as is to test. Spatters a lot. Was just going to prove it works, not pretty (yet).

The main advantage of wire feeder suitcases is increased production. You can get a lot done fast.

The purpose of the little wire and clamp on the feeder is to power the drive roll motor and power the contact solenoid in the machine.

Ive used these machines a lot to weld just about everything. Mild steel to inconel. You can run as small as .023 wire all the way up to 5/64. Ive mostly used them with .045 DualShield II70S, 1/16 8000NI2 and Shieldbright 309.

With the XMT you won't need to worry about the CC setting. The CV setting will produce a superior bead and higher quality weld. With .045 wire I run any where from 24.5 up to 28 volts and around 250 to 300 inches of wire.

Hope this helps and have fun with your new toy,

Toby

Do you have any idea what wire is in it?

The big deal with a voltage sensing feeder is that you can run it off of an engine drive...That's what it's for. Or in a pinch, You can use it as a regular feeder on CV. It is not as responsive on CV as a regular 14 or 19 pin feeder would be but it works. That is it in a nut shell for all Voltage Sensing Feeders.

Yeah I get it now. It is essentially what makes it portable. Instead of being tied close to the power supply, it runs off the main welding leads. Field welders have mega long leads to run from the truck to wherever. With one of these, you can place the wire feeder close to your work, and run long welding cables to it from a CC or CV source. These feeders use the main welding supply current to drive them, whereas bench top feeder use a 24v supply from the connector to drive them, and the welding cables/circuit are essentially separate.

BTW, I am in the process of swapping this to a guy who needs one like this in exchange for his bench feeder and some extra goodies to make up the difference. That would be what we call a win-win.

On the topic of wire feeders, what sort of wire feeder could you use on a lincoln SA-200?
