Manual - Cem Dual Mig 120
The MIG 120 usually comes with reversible drive rolls for 0.6mm or 0.8mm wire. Ensure the groove matches your wire size.
This usually means your shielding gas is off, empty, or there’s a breeze blowing the gas away. If using gasless wire, it means the metal is too dirty.
Inspect the feed roller. Ensure the groove size matching your wire diameter (e.g., 0.6mm or 0.8mm) faces inward toward the machine.
Like any tool, this welder will last longer with regular care: cem dual mig 120 manual

The CEM Dual MIG 120 usually features a switch or tapped voltage control (Low, Medium, High) or a numbered dial (1 through 5 or 6).
Tighten the pressure roller just enough so the wire feeds smoothly. If you block the wire at the torch tip with your gloved hand, the rollers should slip slightly rather than bird-nesting at the drive motor.
Always clean your workpiece before welding. Use an angle grinder or wire brush to remove rust, paint, oil, mill scale, and zinc coatings. Failing to clean the metal will result in porosity, cracking, and a weak weld joint.
