Cut the end of the welding wire cleanly, straighten out the first 10cm, and carefully thread it through the guide tube, over the roller groove, and into the torch liner.
Understanding the electrical and mechanical limits of your welder ensures high-quality welds and prevents equipment damage. 230V AC ($\pm$10%), 50/60 Hz, Single Phase Output Current Range: 30A – 120A Duty Cycle: 10% at 120A, 60% at 60A, 100% at 45A Wire Speed Control: Infinitely adjustable potentiometer

Designed for light material, usually ranging up to 120 Amps. 3. Installation and Setup Guide (Gasless/Flux-Cored)
Example: For thin sheet metal, use Min + 1. For thicker plate, use Max + 2. Wire Speed Dial This controls how fast the wire enters the weld pool. The wire will "push" the torch back or stutter. Too slow: The wire will burn back into the contact tip.
Let’s walk through the most critical setup procedures as outlined in the manual. Cut the end of the welding wire cleanly,
Routine maintenance extends the lifespan of your CEM Dual Mig 120 and ensures consistent arc performance.
The CEM Dual Mig 120 features interchangeable polarity, allowing you to switch between standard MIG (GMAW) and Flux-Cored (FCAW) welding. Standard MIG Welding (Gas Shielded)
Connect your gas bottle regulator, run the gas hose to the rear inlet of the machine, and set the flow rate between 15 and 20 cubic feet per hour (CFH). Gasless MIG Welding (Flux-Cored) Designed for light material, usually ranging up to 120 Amps
Open the side compartment door to expose the wire drive mechanism. Unscrew the plastic retaining nut from the spool spindle.
Regular maintenance is crucial for performance and safety. This simple checklist can extend the life of your CEM Dual Mig 120.
