Cem Dual Mig — 120 Manual

This setup produces clean, slag-free welds perfect for indoor shop work and thin sheet metal.

Connect the ground clamp cable to the Positive (+) terminal and the torch lead to the Negative (-) terminal (DCEN - Direct Current Electrode Negative).

Place your wire spool on the spindle. Ensure the plastic retaining nut provides slight tension so the spool doesn't spin freely and unravel when feeding stops.

Fixed/captive direct-connect torch (non-Euro-coupler style)

Operating a MIG welder involves balancing two primary controls: and Wire Feed Speed (WFS) . On the CEM Dual Mig 120, these are likely simple knobs (possibly with detents for voltage selection). There is no digital interface. cem dual mig 120 manual

Proper setup is critical for achieving clean welds and maintaining operator safety. 1. Power Connection Plug the unit into a dedicated 13A or 16A breaker circuit.

Approximately 20–25 kg (44–55 lbs), making it highly portable Safety First: Essential Precautions

High Voltage (Max-2), Moderate Wire Speed (approx. 6-7) Torch Angle and Movement

Keep your CEM Dual MIG 120 operational by addressing common wear-and-tear points. Common Troubleshooting Scenarios: This setup produces clean, slag-free welds perfect for

0.6mm to 0.8mm steel wire; up to 0.9mm flux-cored wire Cooling System: Fan-cooled (forced air) Weight: Approximately 20–25 kg (44–55 lbs) Control Panel Layout Power Switch: Turns the primary transformer on and off.

Weld only in well-ventilated areas. Use a local exhaust ventilation system or a respirator rated for welding fumes when working on galvanized steel, stainless steel, or coated metals.

The CEM Dual MIG 120 is a versatile, single-phase transformer-based MIG (Metal Inert Gas) welder. The "Dual" designation typically refers to its ability to operate with or without shielding gas, depending on the type of welding wire installed. Ensure the plastic retaining nut provides slight tension

While an official datasheet is unavailable, the model number and user reports suggest these approximate specifications for the CEM Dual MIG 120:

230V AC (Standard European single-phase power) Amperage Range: 30A to 120A (Approximate) Duty Cycle: Typically 10% to 15% at maximum output (120A)
