Because the CEM Dual MIG 120 lacks an auto-set digital display, you must rely on manual charts and physical feedback to dial in your settings. Material Thickness Voltage Setting (Min/Max & 1/2) Approximate Wire Speed (1-10) Recommended Wire Type Gas Type (If applicable) 0.6mm Solid Argon/CO2 Mix 1.2mm - 1.5mm (Auto Body) 0.6mm or 0.8mm Solid Argon/CO2 Mix 2.0mm (Light Tubing) 0.8mm Solid / Flux-Cored Argon/CO2 Mix or None 3.0mm+ (Thick Brackets) 0.8mm Solid / 0.9mm Flux Argon/CO2 Mix or None
Hold the wire tight so it doesn't unspool into a "bird's nest." 2. Feeding the Wire Release the tensioner arm on the drive motor.
The CEM Dual MIG 120 manual lists clear safety warnings. Ignoring them risks fire, electric shock, or eye damage.
Lower voltage or increase wire speed; clean rust/paint off metal; ensure proper Argon/CO2 ratio. cem dual mig 120 manual
By keeping the manual (or a PDF on your phone) next to your welding bench, you ensure that you can quickly solve wire feed issues, decode error lights, and select the right voltage for any gauge of steel. Don’t guess—consult the manual and weld with confidence.
Voltage too low for wire speed; incorrect gas type; bad earth clamp connection.
A: This is usually a wire feed speed (WFS) issue. Try increasing the wire feed speed setting slightly. If you are welding with a standard MIG torch, try holding the gun with a longer "stickout" (the distance from the contact tip to the workpiece). A ½" to ¾" tip-to-work distance is a good starting point. Because the CEM Dual MIG 120 lacks an
Listen for a consistent "sizzling bacon" sound. 🔧 Maintenance and Troubleshooting Common Issues
A: The most common symptom is an inconsistent wire feed that you cannot correct by adjusting the drive roll tension. If you feel unusual resistance when pushing the wire through the torch by hand, or if the wire feed "stutters" while welding, the liner is likely dirty, kinked, or worn out.
The manual states 15% at maximum output (120A). That means weld for 1.5 minutes, then rest for 8.5 minutes. If you weld below 90A, you can achieve a 30% duty cycle. The CEM Dual MIG 120 manual lists clear safety warnings
Keep a fire extinguisher nearby and clear away flammables. ⚙️ Setup and Installation 1. Loading the Wire Spool Open the side panel and unscrew the spool holder. Slide the wire spool on so the wire feeds from the bottom.
Feed the wire manually through the inlet guide tube, over the grooved roller, and into the brass torch liner guide. Lower the pressure arm and lock it into place.
