Brandon,

What may have been a great deal financially for you, sounds like it will be a bit of labor and time for you.

The Firepower welders are decent inexpensive units. I've seen and used a few and noticed that NAPA carries parts and replacements for them.

I would definitely advise you to replace the liner as any deposits or crud from the fire / extenguishing / water will have an impact on the conductivity to the wire.

You may be able to disassemble the gun, clean the contacts and lube the trigger.

As for the wire feed rollers / pulleys and any other metal parts that can be removed, get yourself some Evapo-Rust from a hardware, or Farm supply and soak the parts to clean off the deposits then remove them and clean them with contact cleaner before installing. The shielding nozzle should be cleaned up separately and the contact tips could just be replaced.

You might need to replace the regulator for the shielding gas. I wouldn't mess with cleaning it unless your LWS can do it as a service for you. Also, trade in the cylinder and get a fresh one with clean gas. The valve on the existing cylinder could have problems as well.

Once you get the internals cleaned up, make sure your filler wire is clean, if it was in the fire, get rid of the spool and start with a fresh spool.



After this "mini-rebuild" you should be able to work with the unit to get more accustomed to the settings and performance.
