A friend is closing his metal works shop. He gave me his only 110 volt unit, an old Lincoln Weld-Pak 100. The code is 10172. It cleaned up nicely, but the gun and cables are shot. I found the manual online and it is a flux-core only machine. I also have a Lincoln ST-135 MIG that uses shielding gas so a flux only machine will be handy to have. The manual does not say what gun belongs with the unit. I see Magnum cast on the handle, so I guess it is a Magnum 100L gun? And it is supposed to be set up out of the box for .035" flux-core wire? I would probably use that size wire, or maybe .030". It has the two spade connectors that plug inside the case. It has the knurled roller inside.

My questions is: are all the Magnum 100L guns basically the same? I know the wire connectors differ on some, and the liners and tips are interchangeable depending on what wire you want to use. I see in the Lincoln parts guide catalog that there are two possible guns that might work.
One is the Magnum 100L FCAW 035-045 [spaded lug connector] K530-3. Is this set up just for flux core wire?
The other is the Magnum 100L GMAW 025-035 [spaded lug connector] K530-5. Is this set up for gas shielded wire?
Do the FCAW and GMAW determine the usage?

What I am wondering is, is it possible to get a gun/cable already set up for the flux wire, or do you get a generic set that must be customized for what you are using it for?

Another question I have is, can a Magnum 100L that was used on a 220 volt machine, also work on a 110 volt machine?

I see lots of cheap guns online but I tend to buy OEM whenever possible. I know this is an old machine, but if a modern gun can be used that would be great. Thanks in advance.

Then this one is very clean for it's age. Really, the only thing wrong looks to be the gun and cable. Either it shorted out and burnt up, or it caught welding slag and melted. It was stored under a big table where serious welding took place. I would not be surprised that it suffered from molten shrapnel.

It came today. It is as good if not better than the original Lincoln. Yes, the contact tips, nozzle, and gas diffuser, are all Lincoln 100L specs. The reviews I read are true. It feels solid, and very well made.
I also scored a brand new 12lb spool of Lincoln Innershield flux core wire on Fleabay for about half the going price. My buddy that gave me the machine said he never tried flux core and he wants to see how it welds.
I am currently restoring a 1968 Firebird convertible. I am installing a roll bar that needs floor panel re-inforcements. We will be using this set up to get that done.

Harbor Freight units take the same consumables as well in case you get in a pinch. You likely won't like the innershield on body work. Therefore I should probably come and pick up that car so you don't have to mess with it.
