Mig 120 Manual: Cem Dual

Standard industrial ratings often place these units at roughly 30% duty cycle at maximum output, meaning they require cooling after 3 minutes of continuous welding. Protection Class:

Torch should be Positive (+) and the Earth Clamp Negative (-) .

While a direct PDF from the original factory is rare, the most active archives for these machines are:

These are consumables. If the wire is "stuttering," replace the copper tip at the end of the torch.

Connect the gas hose to a regulator on a CO2 or Argon/CO2 mix bottle. Set the polarity to DCEP (Torch Positive, Earth Clamp Negative). cem dual mig 120 manual

Usually consisting of two toggle switches (Min/Max and 1/2) providing four distinct voltage settings to match material thickness.

Based on standard MIG operating procedures for the 120 series:

Keep your CEM Dual MIG 120 operational by addressing common wear-and-tear points. Common Troubleshooting Scenarios:

If you can't find a CEM manual, look for SIP , Cosmogas , or older Snap-On models from the late 80s and 90s. They often shared internal components and wiring diagrams. 2. Setting Up the Polarity Standard industrial ratings often place these units at

Wear an auto-darkening welding helmet with a minimum shade rating of DIN 10 to protect against ultraviolet (UV) and infrared (IR) rays.

Because official printed manuals for older CEM models can be incredibly difficult to find today, this comprehensive guide serves as your unofficial factory workshop manual, troubleshooting companion, and operational overview. 1. Technical Specifications & Overview

Leave machine turned ON so the fan can cool down the internal transformer. Wait 10-15 minutes.

Torch is POSITIVE (+), Ground Clamp is NEGATIVE (-).

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
