Hi, i'm new here. I'm looking forward to learning a lot and meeting people here. Everyone seems very friendly. Anyway, I sure could use some help with this...
I have a Lincoln 3200HD. It's 25-135 amps. I've had it for about a year and i've just been using the .035" flux core wire it came with and i'm fairly good at it. Just recently I rented a 75/25 agron/c02 cylinder for MIG welding. Here's my setup:
I'm restoring a jeep and the flux-core wire burns through most of the sheet metal on it, so i'm trying MIG. I'm using the .025 wire and I have the gas flow set to 10 L/min. This is the rear right corner of a Jeep Cherokee. I cut this section of panel out because I found covered up accident damage and it was rusted through. The rest of the truck is perfect.
But this is my first time doing bodywork to this extent, and when i tried to fit the replacement piece, the fitment is good, but not perfect, there are some slight gaps....
However, i'm used to being able to cross and fills gaps like that with flux core wire. But I can't cross and fill gaps to save my life with the MIG setup. While MIG welding as a whole is a alot easier, and I can lay down really nice beads with great penetration on a horizonal piece of the same material, this is impossible for me. I haven't tried welding the actual body piece in yet. I have a spare door that is the same exact sheet metal, and i cut some slots in it with the grinder to practice filling them. Here's what happened:
It's on the lowest voltage setting, and the wire feed speed is the 2nd from lowest. It does not burn through this metal at all when you weld on it normally. But when I try and fill the gap, if I go too fast I lose the arc when I cross it, but If I go slow and carefully bring the weld pool across, then it melts away at the edges of the steel.
Is there any special technique that will enable me to weld this in? Or am I going to have to go get another donor panel and try and cut it so there is perfect fitment and no gaps?
