I havent welded in over 10 years and even then it was a stick welder... now Ive got a MIG welder... not the top of the line.. just a tractor supply company welder... not the cheapo cheapo... just the cheaper one lol. Its been working great... but yesterday It started to not feed wire... I could see the line buckling so I tried to un twist it... but it still seems to do it. If I shake the cord while holding it over my head... im 6'6.. it would spit out an inch or so... sometimes if i just tap the gun it sometimes will do it... I thought the tip was going bad because I put some heat on it once and it spit out. Im confused! Prolly confused you too!? But I need to weld up a few things... anybody got any tips or advice to get me out of this "jam" lol.
I'm not familiar with you welder, but take the tip off and see if it feeds, if not, check the tension on the wheel inside that feeds the wire, and make sure you're using the right size wire for the wheel, liner, and tip. Did you step on or bend the line causing damage to the liner?
If you have another tip, swap it out..Sometime's they burr at the end and will cause that to happen.. Also, the sleeve inside the cable can kink or collapse, especially if it's wound tight when not in use or if it get's rolled over or stepped on too much. I always leave the cable laid over the machine and not wrapped up tight to prevent damage to it..that is after having to buy a new one for doing what i said not to do.. By the wire buckling i'm thinking the problem is past the roller's...like something is stopping it inside.
Pull the tip out and see if it will feed wire.If it does,the tib is bad.If it doesn't it is probaly binding in the hose.If there is any kinked wire in the machine,cut it off and pull it out.Start with smooth unkinked wire.
Try to keep your cord from having any tight turns because it can cause the wire to bind up in the liner. Double check your wire feed roller tension. Spool tension needs to be just enough to keep the wire from wanting to unroll the spool. Buy some Lubematic pads and fluid to help slow down buildup inside the liner.
