Finding a manual for vintage welding equipment like the can feel like a scavenger hunt. Because CEM (Costruzioni Elettromeccaniche Milanesi) machines were often rebranded or sold through specific regional distributors, documentation isn't always sitting on a shiny manufacturer website.
Understanding the fundamental capabilities of your CEM Dual MIG 120 ensures you operate the machine within its safe limits and achieve maximum weld penetration. Typically 230V AC (Single Phase, 50/60 Hz) Amperage Range: 30A to 120A
Feed the wire through the guide and into the torch liner. Adjust the wire feed tensioner; it should be firm enough to pull the wire, but not so tight that it flattens the wire. 3. Selecting Your Welding Method Option A: Gasless MIG (Flux-Cored / FCAW) - Recommended for Beginners cem dual mig 120 manual
is an inverter-based system. Key features typically include:
Use a welding helmet with a minimum Auto-Darkening Filter (ADF) shade of 10 to 11. Finding a manual for vintage welding equipment like
Guide the wire through the rear inlet guide tube, over the roller groove, and into the brass liner tube leading into the torch lead.
Open the side compartment door to expose the wire drive mechanism. Unscrew the plastic retaining nut from the spool spindle. Typically 230V AC (Single Phase, 50/60 Hz) Amperage
Designed for standard mini spools (0.7kg to 1kg / 100mm diameter)
DCEP (Direct Current Electrode Positive). The torch lead connects to the positive (+) terminal; the ground clamp connects to the negative (-) terminal. Wire Type: Solid ER70S-6 steel wire. Shielding Gas: 75% Argon / 25% CO2cap C cap O sub 2 mix (for carbon steel) or 100% CO2cap C cap O sub 2 (for deeper penetration on thicker metals).
