Here's the problem. I can't make a decent weld with my new (used) Lincoln welder. The weld crumbles off like crisp bacon. The polarity is set up for FLUX and I was told the wire was FLUX. Maybe it's not FLUX wire.
I just bought this used Lincoln SP-135 PLUS MIG welder. I got a great deal. I'm convinced it's in good working order but I can't make a nice weld bead.
I was told the wire in the machine was FLUX but now I doubt it and think it's gas wire. Is there any way to tell?
Also, the tips look like they are correct for gas welding. My Clarke 130EN was a gas welder and worked fine but this is a much nicer welder. The heat setting knob has much more fine tuning instead of only 4 settings like my Clarke welder had.
Here's the wire info from the web and a few pics below. If it was FLUX wire, would it say FLUX on the spool?
