I'm using a friends Cambell Hausfield FluxCore 80 with .035 wire on 1/8" steel for practice, everything i find on the net says to use high speed on the wire feed, but if i use high speed i get blotch poppy welds, on low speed i get a real nice smooth weld and good penetration. But it should be the opposite no?
The 80 doesn't have enough output for the highspeed with .035 on 1/8. My 125 will weld smooth on 1/8 with .035, but just bearly. Make sure your input voltage is right, no 100 ft extension cord, and make sure your gnd is good. You are running with the absolute minimum of power with a CH welder so you need to make sure everything is perfect. Expect to get about 5 different answers to this question. gary

I am no expert, but what I am offering is based on logic, and a couple of years experience. The correct wire speed is the speed which allows your torch to stay the right distance from the puddle/arc. The right "stickout." If the speed is too low, your torch will move closer to the weld and start to foul. If it is too high, the stick-out will keep growing. You will get "stumping,"--the wire running into cold metal and pushing back on the torch.
Use what works for you, nevermind what you see on the net. You're the guy doing the welding.
You are right on the ragged edge with a CH 80 on 1/8" steel, even with fluxcore.
I seem to recall that the wire speed was fairly low when I was welding
1/8" with a Lincoln SP125+ and fluxcore. I start with what the charts say, adjust as necessary until things are working right.The difference between that machine and a Millermatic 210 was night and day. I about had to relearn how to MIG-weld. I mustered the patience to nurse the little red box along, learned to move out smartly with the 210 doing very similar work -- with MIG rather than fluxcore.
Still can't beat the lil' red box for thin sheetmetal, like autobody. It is a little sweetheart for that sort of work.
bacon sizzling like crazy on a hot griddle is the goal.
interuptions in that sound are imperfections in the weld that reduce strength.

Ah, speaking of lovely sounds, try this nice xmas carol redo:
-- Vidi, Vici, Veni ---
Well the handy core 100 was on sale so i figured i'd give it a try, wow night and day difference from the old unit, good welds and penetration off the bat, and yes got the super sizzling bacon sound :D
