Reinstall the retaining nut, tightening it just enough to prevent the spool from freewheeling when the feed stops. 3. Threading the Wire Drive System Flip down the tension arm on the wire feed mechanism.
Flip the pressure arm down over the roller and tighten the tension knob. Do not overtighten. The tension should be just enough to feed the wire smoothly. If you pinch the wire tightly with your gloved fingers at the torch end, the roller should slip rather than bird-nesting at the drive roll.
Open the side cabinet. Place the wire spool on the hub. Adjust the tension nut so that the spool spins freely but does not freewheel when you stop feeding. cem dual mig 120 manual
Accommodates 0.6mm to 0.8mm solid steel wire, and 0.9mm flux-cored wire
Start with these settings, then listen for the "sizzling bacon" sound to fine-tune. Reinstall the retaining nut, tightening it just enough
This is the sweet spot for the Dual Mig 120. It is brilliant for welding car panels, floor pans, and exhaust systems. The low-end amperage control is smooth enough to weld thin sheet metal without blowing holes, which is difficult with cheaper, "choppy" welders.
DCEN (Direct Current Electrode Negative). The torch lead connects to the negative (-) terminal; the ground clamp connects to the positive (+) terminal. Wire Type: Flux-cored gasless wire (E71T-GS). Flip the pressure arm down over the roller
A loud, crisp crackle like frying bacon indicates a perfect balance of voltage and wire speed.
If using gas: Check if the gas cylinder is empty, the regulator is off, or wind is blowing away the shielding gas.
