The is a classic entry-level welder known for its versatility in handling both gas-shielded (MIG) and gasless (flux-cored) welding. While physical copies of the manual can be rare for this older model, the operational steps and maintenance are consistent with standard 120A dual-process machines. Quick Specifications Input Power: 230V / 50-60Hz (standard household outlet). Welding Current: 30 – 120 Amps. Duty Cycle: Typically 15% at 105A; 100% at 30A.
Torch is POSITIVE (+), Ground Clamp is NEGATIVE (-).
If you’ve recently purchased a CEM Dual MIG 120 or are considering one for your home workshop, you already know that this compact welding machine punches above its weight class. However, like any sophisticated piece of equipment, having access to the is not just recommended—it is essential for safety, performance, and longevity. cem dual mig 120 manual
None required. The chemical flux inside the hollow wire creates its own protective atmosphere as it melts. 6. Operating Instructions and Welding Techniques
Typically features a combination of Min/Max and 1/2 switches. This provides four distinct voltage steps to match the thickness of your workpiece. The is a classic entry-level welder known for
Remove the welder from the box. Verify you have:
Every few spool changes, use compressed air to blow out dust from the torch liner to ensure smooth feeding. Troubleshooting Chart Probable Cause Corrective Action Wire slips or feeds unevenly Loose tension arm / Wrong roller groove Welding Current: 30 – 120 Amps
CEM (Costruzioni Elettromeccaniche Ancona) was a well-regarded Italian manufacturer known for producing robust, compact welding machines widely used in automotive restoration, light fabrication, and home workshops. Because these machines are no longer in active production, finding original documentation can be challenging.
Yes, but you need a Teflon liner, 100% argon gas, and 0.035” aluminum wire. The manual warns that aluminum requires a push-pull torch for best results; the standard torch may cause birdnesting.
Supports 0.6mm to 0.8mm solid wire (with gas) and up to 1.0mm flux-cored wire (gasless).
Illuminates yellow or red when the machine exceeds its duty cycle. The welder will stop feeding wire until it cools down.
