Cem Dual Mig 120 Manual Patched (2025)

Setting 2 + Max: Maximum power output (ideal for thicker steel plate).

If you find a manual for a CEM Dual MIG 100 or 150, it is likely very similar to the 120. The internal components and operation principles are usually standardized across the range.

: Open the side panel and mount the wire spool on the spindle. Ensure the wire unrolls from the bottom to prevent tangling.

Replace them frequently. A worn, ovalized contact tip hole leads to arc instability. cem dual mig 120 manual

Set your Voltage switch according to material thickness (e.g., Min-1 for 1mm sheet metal). Set your Wire Speed to a mid-point setting (around 4 or 5).

Slide the wire spool onto the spindle, ensuring the wire feeds from the bottom of the spool toward the drive roller mechanism.

This is where the CEM Dual Mig 120 destroys its competition (like generic "no-name" Chinese welders). Setting 2 + Max: Maximum power output (ideal

Yes, but you need a Teflon liner, 100% argon gas, and 0.035” aluminum wire. The manual warns that aluminum requires a push-pull torch for best results; the standard torch may cause birdnesting.

Unclog liner; back off drive roller pressure; ensure tip matches wire diameter exactly.

Use heavy-duty, flame-resistant split-cowhide welding gloves and a leather welding jacket. Avoid synthetic fabrics, which can melt onto your skin when exposed to sparks. : Open the side panel and mount the
