Remove the contact tip and nozzle from the torch, then pull the trigger until the wire emerges.
What and metal type are you planning to weld?
Do not turn off the machine. Leave the fan running to cool the internal transformer until the light goes out. Reduce output settings or slow down welding pace. cem dual mig 120 manual

The CEM Dual MIG 120 is a capable entry-to-intermediate MIG welder when operated within its duty cycle and with correct setup. The dual voltage feature offers flexibility for home users, while the gas/gasless option allows outdoor welding without shielding gas. Regular cleaning and proper polarity selection are the two most critical factors for reliable performance. Leave the fan running to cool the internal
The torch/gun must be connected to the Positive (+) terminal, and the earth clamp must be connected to the Negative (-) terminal (DCEP - Direct Current Electrode Positive).
Proper tension on the wire drive system prevents bird-nesting (tangled wire) and erratic feeding.
