WELDER CONTROLS (Items 9 through 14 )

9.OUTPUT RANGE SWITCH & OUTPUT CONTROL

These two controls allow you to select between various welding output slopes and adjust the desired welding output. Refer to Table B.1 for a description of how these two controls work.

1If the OUTPUT RANGE switch is positioned between settings the previous setting is maintained until the switch is properly positioned on a setting.

2OUTPUT CONTROL also controls O.C.V. while in the 6 sloped out- put ranges.

10. DIGITAL OUTPUT METER

The digital output meter is located in the center of the control panel between the two large control knobs. The meter allows the output current level to be set prior to welding. During the welding process the meter dis- plays the actual output current.

11. WELDING TERMINALS SWITCH

The toggle switch on the control panel labeled “Welding Terminals Always On” and “Welding Terminals Remotely Controlled”: is used to control the operation of the “solid state contactor” which allows for the selection of “Hot” or “Cold” welding terminals.

With the switch in the “Welding Terminals Always On” position the contactor is closed and the welding termi- nals are always “Hot”.

With the switch in the “Welding Terminals Remotely Controlled” position the contactor operation is con- trolled by an Amptrol, Arc Start Switch or some other type of triggering device through the use of a control cable connected to the 6-pin MS connector.

When the triggering device is pressed the contactor is closed and the welding terminals are “Hot”.

When the triggering device is released the contactor is opened and the welding terminals are “Cold”.

12. LOCAL /REMOTE SWITCH

The toggle switch on the control panel labeled “Local/Remote” gives the operator the option of con- trolling the output at the welder control panel or at a remote station.

For remote control the toggle switch is set in the “Remote” position.

For control at the welder control panel, the toggle switch is set in the “Local” position.

13. 6 - PIN CONNECTOR

The 6-pin connector located on the control panel allows for connection of Remote Control accessories.

14. WELD OUTPUT TERMINALS + AND -

These 1/2 - 13 studs with flange nuts provide welding connection points for the electrode and work cables. For positive polarity welding the electrode cable con- nects to the “+” terminal and the work cable connects to this “-” terminal. For negative polarity welding the work cable connects to the “+” terminal and the elec- trode cable connects to this “-” terminal.

AUXILIARY POWER CONTROLS

(Items 15 - 19 )

15. 120/240VAC RECEPTACLE

This is a 120/240VAC (14-50R) receptacle that pro- vides 240VAC or can be split for 120VAC single phase auxiliary power. This receptacle has a 50 amp rating. Refer to the AUXILIARY POWER RECEPTACLES sec- tion in the installation chapter for further information about this receptacle. Also refer to the AUXILIARY POWER OPERATION section later in this chapter.

16. 50 AMP CIRCUIT BREAKERS These circuit breaker provide separate overload cur- rent protection for each 120V circuit at the 240V recep- tacle.
