Cem Dual Mig 120 Manual

A standard rocker switch that illuminates when the machine is powered on and the internal cooling fan begins to run. 2. Voltage/Power Output Selectors

If you ignore this table in the , you will get excessive spatter, poor penetration, or a unstable arc.

Adjust the drive roll tension: It should be tight enough to feed the wire but loose enough to slip if the wire sticks to the contact tip.

Because the CEM Dual MIG 120 lacks an auto-set digital display, you must rely on manual charts and physical feedback to dial in your settings. Material Thickness Voltage Setting (Min/Max & 1/2) Approximate Wire Speed (1-10) Recommended Wire Type Gas Type (If applicable) 0.6mm Solid Argon/CO2 Mix 1.2mm - 1.5mm (Auto Body) 0.6mm or 0.8mm Solid Argon/CO2 Mix 2.0mm (Light Tubing) 0.8mm Solid / Flux-Cored Argon/CO2 Mix or None 3.0mm+ (Thick Brackets) 0.8mm Solid / 0.9mm Flux Argon/CO2 Mix or None cem dual mig 120 manual

Ensure the correct drive roll groove is used for the wire size (typically 4. Operation: Starting to Weld

Slide the wire spool onto the spindle, ensuring it feeds from the bottom.

Install the wire spool (usually 2 lbs) ensuring it unwinds from the bottom.

Connect the gas hose to a regulator on a CO2 or Argon/CO2 mix bottle. Set the polarity to DCEP (Torch Positive, Earth Clamp Negative).

Usually consists of one or two rocker switches marked 1 - 2 and Min - Max . These switches control the transformer taps to alter the welding voltage: Adjust the drive roll tension: It should be

The torch/gun must be connected to the Positive (+) terminal, and the earth clamp must be connected to the Negative (-) terminal (DCEP - Direct Current Electrode Positive).

For hobbyists and light-duty shop users, the CEM Dual MIG 120 (per its manual and typical specs) is a practical, low-cost MIG solution—easy to set up and use for small repairs and thin-gauge fabrication. Its limitations are duty cycle, build robustness, and somewhat basic documentation; buyers should manage expectations and keep spare consumables on hand.
