Inspect the copper contact tip frequently. If the hole becomes oval-shaped or clogged with spatter, replace it. Always match the tip size to your wire size (e.g., use a 0.6mm tip for 0.6mm wire).

Ensure the gas cylinder is open and the regulator is set to 10-15 CFH. Check for leaks in the hose.

Ensure the welder is unplugged from the wall. cem dual mig 120 manual

Too little tension on the drive roll; or burnt-out feed motor.

Lower voltage or increase wire speed; clean rust/paint off metal; ensure proper Argon/CO2 ratio.

By using the CEM Dual MIG 120, you acknowledge that you have read and understood the instructions and safety precautions outlined in this manual.

An orange or yellow warning light. If the machine exceeds its safe operational temperature (duty cycle limit), this light activates, and the machine stops welding. Leave the machine turned ON so the internal fan can cool the transformer until the light goes out. 3. Machine Setup & Installation Choosing Gas vs. Gasless (Dual Functionality)

Voltage too low for wire speed; or incorrect polarity for flux-core wire.
