Cem Dual Mig 120 Manual Jun 2026
Your includes a maintenance log. Here is the condensed version:
The manual states 15% at maximum output (120A). That means weld for 1.5 minutes, then rest for 8.5 minutes. If you weld below 90A, you can achieve a 30% duty cycle.
Why? Flux-cored wire requires less heat in the base metal and more penetration; reversing polarity reduces spatter. cem dual mig 120 manual
Once the wire emerges from the neck, slide the correct contact tip size (e.g., 0.6mm or 0.8mm) over the wire and screw it tight. Replace the gas shroud. Setting the Parameters: Voltage and Wire Speed
If using shielding gas, handle cylinders with care and avoid gas leaks. Your includes a maintenance log
Ensure the welder is unplugged from the wall.
The Dual Mig 120 usually features rocker switches to adjust voltage. Sets the general power range. 1/2: Fine-tunes the voltage within that range. If you weld below 90A, you can achieve a 30% duty cycle
Check gas bottle levels/flow rate; weld indoors away from drafts; verify DCEP polarity. Duty cycle exceeded; thermal overload protection activated.
