Sticky Wire Feed
Can any one suggest owt for this? The lead assembly between the trigger and box on my MIG has always been coiled and unless I keep this bend radius in
it when I'm welding, it just won't feed properly and looks like blackberry flavoured bird droppings! It just seems to be worse lately. Is
there a silicon spray or summat I can do to grease the liner?

Mabye just get a new liner for it, unless it's something oddball any decent welding supplies place will have one for a few quid.

Has the wire become rusty at all? is the wire feed adjusted properly? trigger the wire through your thumb and finger, adjust it until you can just
about stop it and it starts to slip on the clamp wheels, if it's to tight it will buckle and jam

It works great when I keep the natural curve in it its just when its a little against the curve so I don't think its the motor. The wire
ain't rusty at all. Maybe a new liner then as said.

Try a Teflon liner instead of the coiled wire one. What kind of mig is it? DIY migs don't have the best record for wire feeding, my SIP was
feeble.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

I used to squirt a little WD40 down my liner now and again, don't go mad as it's flammable
A new liner is cheap enough though worth a try
Have you checked the wire feed roller pressure, if it's not set right it will snag and slip or buckle the wire internally

The liner in already is teflon not wire, its just taken on a coiled shape because of the way the thing was stored when I bought it. Wire pressure is
fine as all works well when no undue pressure is against the natural coil. I'll try a quick squirt of oil I think until the weekend when
I'll try and get a new liner.

Trigger the wire through your finger and thumb if you can easily stop the wire, then the wire feed pressure is to low.
This may account for you being able to weld fine when the torch wire is coiled up in it's set state, and not welding properly when you
straighten it because of the increase in friction

I have always used a drop of parafin squirted down the liner, works every time. hth Ray

bit of wd40 on a small piece of scotchbrite pad in a small bulldog clip round the wire where it goes into the liner.
won't get round crap diy quality torches and liners though
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning
