Cem Dual Mig 120 Manual Jun 2026

Generally rated around 10%–35% at max amperage, meaning it’s best suited for shorter bursts of welding rather than continuous industrial use. Step-by-Step Setup Guide

Increase the tension on the wire drive rollers and ensure the spool tension is not too tight.

Lack of gas shielding; wind blowing gas away; wrong polarity.

0.6mm to 0.8mm (Solid steel, stainless steel, or flux-cored wire) Generally rated around 10%–35% at max amperage, meaning

Understanding the limits of your machine is the first step to a successful weld. 230V AC (Standard household outlet) Current Range: 30 – 120 Amps Duty Cycle: Typically 10% at 100A; 60% at 45A Wire Compatibility: 0.6mm to 0.8mm (Solid or Flux-cored) Gas Options: CO2, Argon/CO2 Mix, or Gasless (Flux-cored) 🚦 Safety First Before powering on, ensure you have the following: Auto-darkening helmet: Set to shade 9-11. Leather gloves: To protect against UV and heat.

Setting 4 (Max + 2): Maximum heat for thick plate welding up to 4mm-5mm. Setting 4 (Max + 2): Maximum heat for

If you’ve just picked up a second-hand CEM Dual MIG 120, or you’re trying to get an old workshop workhorse back in action, you’ve likely run into the same problem as many other welders: the paperwork is missing. CEM (City Engineering Manufacture) machines are known for being robust, British-made welders, but they are older machines, and original printed manuals are becoming collector's items.

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:

The CEM Dual MIG 120 usually features a switch or tapped voltage control (Low, Medium, High) or a numbered dial (1 through 5 or 6).
