5 OPERATION 5.5 Firepower MST-200 and Firepower FP-200 features Wiredrive motor circuit breaker The 4A circuit breaker protects the unit from electrical faults and will operate in the event of a motor overload. NOTE! If a circuit breaker trips, a short cooling period must be allowed before an attempt is made to reset the unit by pressing the circuit breaker reset button.
5 OPERATION Attaching the ESAB fusion 180 A MIG gun Figure 27: Attaching MIG gun 1 MIG gun adapter 2 MIG gun connector 1) Open side panel and loosen thumb screw. 2) Fit the MIG gun to the power source by pushing the MIG gun connector into the MIG gun adapter.
3) Fit the MIG gun to the power source, see "Attaching the ESAB fusion 180 A MIG gun" section. 4) Connect the work lead to the positive welding terminal (+). If in doubt, consult the electrode wire manufacturer.
5.11 Setup for MIG (FCAW) welding with flux core (gasless) wire 1) Select MIG mode with the process selection control see " Firepower MST-200, Firepower FP- 200 controls, indicators and features" section. 2) Connect the MIG polarity lead to the negative welding terminal (-). If in doubt, consult the electrode wire manufacturer.
5 OPERATION 5.13 Setup for LIFT TIG (L-GTAW) welding (only for Firepower MST-200) 1) Select LIFT TIG mode with the process selection control, see section 5.4.1 " Firepower MST- 200" 2) Connect the TIG torch to the negative welding terminal (-). Welding current flows from the power source via dinse type terminals.
3) Select MMA mode with the process selection control, see section 5.4.1 " Firepower MST-200". WARNING! Before connecting the work clamp to the workpiece make sure the electricity supply is switched off.

These are the wire speed control (see "Firepower regulator" section) and the welding voltage control, see " Firepower MST-200, Firepower FP-200 controls, indicators and features" section. The welding current is determined by the wire speed control, the current will increase with increased wire speed, resulting in a shorter arc.
Electrodes are generally connected to the electrode holder. The electrode holder is connected to the positive polarity. The work lead is connected to the negative polarity and it is connected to the workpiece. If in doubt consult the electrode data sheet or your nearest accredited ESAB distributor.
