Maintain a distance of 1/4" to 1/2" between the contact tip and the metal workpiece. An excessive stick-out weakens electrical current and destabilizes the arc. 7. Maintenance and Care
Remove the gas nozzle and unscrew the copper contact tip from the end of the torch.
Because settings vary based on joint design and technique, use this chart as a baseline starting point: Material Thickness Welding Mode Voltage Switch 1 Voltage Switch 2 Wire Speed Dial Gas (0.6mm wire) 18-16 Gauge (1.2 - 1.6mm) Gas / Gasless 14 Gauge (2.0mm) Gas / Gasless 1/8 inch (3.2mm) Gasless (0.9mm wire) Maintenance and Troubleshooting
Check the liner inside the torch cable. Blow out metal dust with compressed air or replace the liner if the cable was kinked. Adjust the drive roll tension screw slightly. cem dual mig 120 manual
Achieving a high-quality weld requires balancing your travel speed, torch angle, and machine settings. Preparing the Metal
With patience and a bit of resourcefulness, this classic machine can be a rewarding tool for any DIY workshop.
Close the pressure arm and tighten the tension screw. Tip: Do not overtighten. The roller should slip slightly if the wire encounters a hard blockage. Maintain a distance of 1/4" to 1/2" between
Tighten tension knob; blow out or replace liner; swap out worn contact tip.
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
Use proper welding masks, gloves, and protective clothing to protect against sparks and arc rays. Maintenance and Care Remove the gas nozzle and
Spray the inside of the gas shroud with anti-spatter spray to prevent metal droplets from bridging the gap between the live tip and the grounded shroud.
Protects the machine from overheating during prolonged use.
Finding parts for a discontinued model is often the biggest hurdle. Here's a direct path to solving that problem.
Lay the MIG torch cable out completely straight on the floor to minimize resistance inside the liner.
If you want, I can extract step-by-step setup instructions, a recommended consumables/spare parts list, or a simple welding parameter chart tailored to 0.8 mm and 1.0 mm wire — which would complement the manual.
