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.

: Depending on the manufacturer and model specifics, there might be concerns about the availability of spare parts, service support, and overall durability.

Lay the MIG torch cable completely straight on the ground to prevent friction kinks. cem dual mig 120 manual

Leave the machine turned ON. Allow the fan to run until the light turns off.

None required. The chemical flux inside the hollow wire creates its own protective atmosphere as it melts. 6. Operating Instructions and Welding Techniques

DCEP (Direct Current Electrode Positive). The torch lead connects to the positive (+) terminal; the ground clamp connects to the negative (-) terminal. Wire Type: Solid ER70S-6 steel wire. Shielding Gas: 75% Argon / 25% CO2cap C cap O sub 2 mix (for carbon steel) or 100% CO2cap C cap O sub 2 (for deeper penetration on thicker metals).

Clogged contact tip or dirty liner; excessive spool brake tension. Check gas bottle levels and regulator flow rate

Insufficient drive roller tension; clogged torch liner; deformed contact tip.

: Operating two torches simultaneously might add complexity to the welding process, potentially requiring more skill and coordination from the operators compared to single-torch welding.

: MIG welders typically offer adjustable settings for voltage, wire feed speed, and sometimes provide pulse welding capabilities. These features allow for a good degree of control over the welding process, making it suitable for various thicknesses and types of materials.

The key to using the CEM Dual Mig 120 is listening to the sound of the arc. With the voltage and WFS correctly balanced, you will hear a smooth, consistent "crackling" or "sizzling" sound, often compared to frying bacon.

Are you currently experiencing any (e.g., wire jamming, weak arc, no power)?

If the duty cycle is exceeded, the machine will shut down. Wait for the fan to cool it down. 6. Maintenance This link or copies made by others cannot be deleted
