5.Mode Switch
This switch chooses the proper welding mode. Choose from GMAW (MIG), FCAW
NOTE: The welding cables must also be attached to the proper output studs for best welding performance (See “Output Connections” section).
6.Wire Feeder Voltmeter Switch
This switch changes the polarity of the wire feeder voltmeter sense lead, if the wire feeder is so equipped. Set to match the electrode polarity so that the wire feeder voltmeter can display the welding voltage. This switch has no effect on the welding output polarity of the
7.Output Terminals Switch
This switch controls the
8.Power Switch and Pilot Light
Turns the
9.Circuit Breakers
These circuit breakers provide overload protection for the auxiliary circuits. One 15 amp breaker is for the wire feeder 115V AC circuit (31 and 32), another 15 amp breaker is for the spare 115V AC auxiliary circuit (33 and 34). The 10 amp breaker is for the 42V AC wire feeder circuit (41 and 42).
10.Strain Reliefs
These strain reliefs are provided for control cables going to the terminal strips.
11.Terminal Strip Door
This access door provides protection for the terminal strip connections. (Lead numbers shown for this panel in Figure 3). The door can be opened by turning the fastener
12.Wire Feeder Receptacle
This is the standard Lincoln,
13.Rating Plate
This plate contains important information regarding the code number, serial number, input voltages, input currents, and output ratings of the
14.Digital Ammeter
Displays the output amperage when welding. If set to the SMAW (stick) mode, the ammeter displays the preset welding current when not welding. By using this meter, the output current can be set to a predetermined value before an arc is struck. This permits repeatability when changing and setting procedures. The output current can be preset from the Output Control or from a remote control attached to the terminal strip.
15.Digital Voltmeter
Displays the output voltage as measured on the output studs of the machine.
NOTE: Due to voltage drops in the welding cables and at cable connection points, the actual arc voltage may be lower than that displayed on the voltmeter. Use welding cables of the proper capacity and make sure all connections are tight to minimize this effect.
If set to either the GMAW, FCAW, or SAW modes, this meter can display the preset welding voltage when the secondary output contactor is open (usually when the gun trigger is released). By using this meter, the output voltage can be set to a predetermined value before an arc is struck. This permits repeatability when changing and setting procedures. The output voltage can be preset from the Output Control or from a remote control attached to the terminal strip. The only exception occurs when the
