OPERATION

Never operate the power source with the cover re moved. In addition to the safety hazards, lmproper cooling may cause damage to the components. Keep side panels closed when unit is energized. Welding helmet, gloves, and other personal protec- tion should always be worn when welding.

3.1 CONTROLS (See Figure 3.1)

3.1.1PowerSwitch(ON-OFF)/(I-O)

The power switch is located on the front panel of the power source. In the OFF ("0") position, the unit is shutdown however, power is still present at the switch itself. To totally shut down the power source, power must be disconnected at the line disconnect switch or the fuse box.

With the switch in the ON ("I") position, power is provided to the main transformer and the low voltage control circuitry.

3.1.1.1 Power Indicator

This white light will indicate that the power switch is in the ON position and power has been applied to the main transformer and low voltage circuitry.

3.1.2 Arc Force Control.

This control is used for stick welding only.The lower settings provide less short circuit current and a softer, more stable arc. The higher settings provide more short circuit current and a forceful, more penetrating arc. For most Stick welding, set the knob at 3 or 4 and readjust up (forceful) or down (softer) as desired.

3.1.3 Contactor, On/Remote Switch

The Contactor Control switch is located on the front panel of the power source. In the ON position, the solid state contactor is energized and output power is avail- able at the output terminals. The REMOTE position allows the solid state contactor to be controlled from a remote control.

3.1.4 Current Panel/Remote Switch

With this switch in the PANEL position, output current is controlled by adjusting the potentiometer on the front panel to the desired output. In the REMOTE position, output is controlled using an optional remote control via receptacle J2.

3.1.5 Current Control

This control allows the operator to adjust the output current. Placing the Panel/Remote switch in the RE- MOTE position disables the current control on the front panel.
