Getting Started with the CEM Dual MIG 120 : A Hands-On Guide If you’ve recently acquired a CEM Dual MIG 120

0.6mm to 0.8mm solid steel wire; 0.8mm to 0.9mm flux-cored wire

If you’ve just inherited one of these Italian-made workhorses or picked it up at an estate sale, here is the essential "manual" and guide to getting it running. 1. Identifying Your Machine

Because these are "old school" transformer machines, they are heavy and durable. Unlike modern inverter welders that are packed with digital menus, the Dual MIG 120 relies on simple, robust controls. However, without the manual, deciphering the voltage taps and wire feed settings can be a game of trial and error. cem dual mig 120 manual

Use a shielding gas (e.g., Argon/CO2 mix) and connect the regulator to the bottle. 4. How to Use the CEM MIG 120 Controls

Supports 0.6 mm and 0.8 mm solid wire (for gas) and up to 1.0 mm flux-cored wire (for gasless). Duty Cycle: Typically around 20% at 100A-120A.

Familiarize yourself with the interface before plugging in the machine. Getting Started with the CEM Dual MIG 120

Always grind away rust, paint, and oil from the metal surface before welding to avoid porosity and weak welds.

A genuine is typically broken down into six core chapters:

Located on the front or rear panel; illuminates when the system is live. Unlike modern inverter welders that are packed with

Reinstall the retaining nut, tightening it just enough to prevent the spool from freewheeling when the feed stops. 3. Threading the Wire Drive System Flip down the tension arm on the wire feed mechanism.

It can typically run Gas (with solid wire) or Gasless (with flux-core wire) by reversing the polarity.
