Thread: Mig torch liner

Various tool stores have them,, like Alltools etc, but you’ll be able to get all you need at CIG for it.

Maybe best to pull the liner out and take it to BOC or similar to see if they have one similar - Hopefully Toxic will chime in, he’ll be able to point you in the right direction as he does Welders for a living.

Sometimes a quick blow out with air helps.
Just take whole torch, or at least identify it. Any decent welding outlet will have them. May need to trim to length.

Not using gasless wire? it can be a bugger to feed sometimes.

Yes gas less, was fine then started playing up.

Sometimes its recomended to use different (knerled) feed rollers with gassless. The temptation to use excessive roller tension to overcome poor feeding seems to distort the wire, making it worse.

Already has a knurled wheel and working fine for about 3 years so liner is the suspected culprit.

Chuck up a pic of the torch.
My bet is a Tweco variant if it's a CIG of that vintage. There are a few key styles of MIG torches, but between Binzel and Tweco, you have 90% of the torches out there covered.

Yep, just take it into a welding shop and they will match the type, you just snip it to length.

I think sometimes they get a little arc go off in them or something or they pull grit into the liner and they're bad after that. I wouldn't bother cleaning them, the problem could be anywhere, for reliability just replace it. I also do all of the torch consumables at the same time - welding supplier will have these too.
