Default Bad MIG wire.

I picked up a spool of 70S 6 wire from a buddy selling off a bunch of stuff for somebody else. It was a 30 pounder of .035. Still in a sealed bag in the box. I use it a lot, so it was a good deal. I did some work for him at the same time, as well trade favors quite a bit.

I ran out of the LWS store brand, Weldcote, or Prostar or something, so I put the spool on. After a short time I started suffering from birdnests, wire slipping in the rolls, and wire stuck at the tip. Put in a new liner, multiple tips, adjusted the rolls tension, etc. Finally had enough today and pulled the last spool out of my field feeder and put it in, problems gone.

The spool is from 1983. I wonder if wire has improved enough over the last 30 years that it just feeds better though a 15' gun where it wouldn't back then. Both wires measure .033 on my digital calipers.

Think I would have started, by replacing the wire myself. Reason being that was the one thing changed.

The likely hood of a torch or liner failure from one wire spool to the next seems remote to me. Those parts would have given some sort of notice, hint of a pending break down, as in intermittent.

The good, got the liner, tips and roller tension all set for the next good while.

Not that i'm a know it all... just my thinking.


Maybe something going on with the spool itself....

Haven't had a bit of trouble since swapping it out.

Bad mig wire can be a struggle to work with, I've changed wire, had it run fine for about 1-2 hours, then go to shit. I stopped buying Radnor wire (Airgas product), because of rotten wire.

I switched to Lincoln L-56 wire, quite a while back and now its the only wire I run.

Bad wire can really be a bitch, and there is more bad wire out there than you
think. Cheap wire is generally, IMO, not worth the trouble when you are
trying to make a living. The down time and chasing problems is not worth it.

L-56 is all I buy now, I don't run enough wire to chase deals. But I will add
for what Lincoln charges, it better be damn good wire, and it is.

What he said.

Even with my living in Humid Heaven down here, keeping a few packs of humid suck crystals and Lincoln wire on the rollers, keeps my Millers happy, me happy and my pocket as well.

I will buy Hobart equiv on a Sunday due to the LWS being closed or Lowes having an empty shelf on the weekends for the Lincoln wire.

I had a run of bad spools that cracked on the hub and caused all kinds of problems.
I have since been running nothing but L-56 too.

My LWS doesn't stock it but I have been buying the 11# spools at Lowes for $34 which I think is not a bad deal and they always have it on the shelf.

Bought a 12.5 pound spool of l56 today. Was going to run it in my feeder today but forgot my spool spacer. I'll try it in my shop feeder. I had been running Washington alloys wire but the lws is now carrying a brand I don't like.

My Spool-Arc 86, and Lincoln L-56 are a good backup wire to this stuff.

Scott, there is a spool of this wire on our MM350P at work. Do you like it? Any particular reasons?

If I had to hazard a guess as to why, I would think that one particular individual at work asked for it. Not sure what dia wire it's in but will check if any are interested.

Free shipping could be a plus considering the price.
