  • Weldmart.com – Specializes in Century parts and manuals.

3. Changing Polarity (For Gas vs. Flux-Core)

This is the most referenced page in the manual. Inside the compartment (often behind the wire spool), you’ll find two terminals: Electrode (torch) and Work (clamp). Manualslib

  • For flux-cored wire (no gas): Set polarity to DC Electrode Negative (DCEN). Connect torch to negative (-), work clamp to positive (+).
  • For solid wire with C25 gas: Set polarity to DC Electrode Positive (DCEP). Connect torch to positive (+), work clamp to negative (-).

The manual includes a clear illustration of how to swap the cables. Ignoring this step leads to excessive spatter, poor penetration, or a stuttering arc.

Trigger circuit: When torch trigger closed, it closes the main contactor relay sending welding voltage to the wire (live torch).

Step 1: Mounting Wire Spool

  • Open the side door.
  • Remove the spindle nut and spring.
  • Place the 2 lb spool of 0.030” or 0.035” flux-cored wire on the hub (wire should unwind clockwise).
  • Reinstall spring and nut – not too tight.
