I have a Hobart Handler 140 and ever since I got the welder on occassion it will jamb up. I have adjusted the tensioner and have it on the correct wire size/setting. I cannot figure out why it keeps jambing up. I am using the correct wire.

Any suggestions or did I possibly set this up wrong?
TIA

 

we have a lincoln at work that does that from time to time and boy is it frustrating.

 

It can be caused by having too many bends in your lead cable. Bends add resistance that fights the wire's efforts to move through the liner of the lead. It can also be that your tip is dirty or has something obstructing smooth movement of the wire. Basically, one way or another, your rollers are pushing the wire, but the wire's seeing resistence that's not letting it go through the lead as easily as it should.

 

The welder that we have at work does that somtimes when the tip gets dirty it jams the wire.

 

A little off topic, but is the spool of wire suppose to unravel like crazy when you take the tape of ? I tried putting on a new spool and if I did not keep a hand on the cable, it would unravel really fast.

Yup that happens, just always becareful and when you roll it up make sure you dont tangle it.

Yeah, I actually just cut if off because so much unraveled.

 

Man that is frustrating. It happens to me but only when I use aluminum wire. When I put the wire to weld steel back in its fine.

 

when they unravel on me i toss em out, tightly spooled works alot better, anyway you have to adjust your pressure on the rollers. to do this have the wire out at the tip then put your palm over the tip (so the wire will be pushing on your hand) then u tighten up the rollers until its at the point that it will just spin on the wire when it hits your hand. you dont want it to keep pushing on the wire when it hits something. that in a nutshell is how you set the roller pressure. and like dude said when you weld try to have the least possible bends in the gun.
good luck

That's why people usually use "spool guns" for aluminum...that way you have much less lead to push the wire through. You can also us a "push-pull" gun, that has rollers on the machine that push the wire (like yours), but also has rollers in the head of the gun that pull the wire.

 

I've messed with the pressure on the rollers several times and have concluded that this was not the problem. I also have made sure there is no loops or kinks. I have gotten really frustrated with this thing b/c it seems like I am constantly re-feeding the sire b/c of the kinks!
