1If the WELD MODE switch is positioned between settings the pre- vious setting is maintained until the switch is properly positioned on a setting.

2OUTPUT also controls O.C.V. while in the 5 sloped output ranges.

10. DIGITAL OUTPUT METERS

The digital output meters are located in the center of the control panel between the two large control knobs. The digital meters allow the output voltage (CV-WIRE mode) or current (CC-STICK, PIPE and TIG modes) to be set prior to welding using the OUTPUT control dial. During welding, the meter display the actual output voltage (VOLTS) and current (AMPS). A memory fea- ture holds the display of both meters on the seven sec- onds after welding is stopped. This allows the operator to read the actual current and voltage just prior to when welding was ceased. While the display is being held the left-most decimal point in each display will be flash- ing. The accuracy of the meters is + or - 3%.

11. WELDING TERMINALS SWITCH

The toggle switch on the control panel labeled “Weld Terminals On” and “Remotely Controlled”: is used to control the operation of the “solid state contactor” which allows for the selection of “Hot” or “Cold” weld-

ing terminals.

With the switch in the “Weld Terminals On” position the contactor is closed and the welding terminals are always “Hot”.

With the switch in the “Remotely Controlled” position the contactor operation is controlled by an Amptrol, Arc Start Switch or some other type of triggering device through the use of a control cable connected to the 14- 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”.

NOTE: The new Chopper Technology control circuitry automatically senses when a remote output control pot is plugged into either amphenol. Therefore, there is no need for a local / remote switch.

12. 6 - PIN CONNECTOR

For attaching optional remote control equipment. When in the CC-STICK, PIPE, and CV-WIRE modes and when a remote control is connected to the Amphenol, the auto-sensing circuit automatically switches the OUTPUT control from control at the welder to remote control .

When using the TOUCH START TIG mode with a TIG Module connected, the OUTPUT control is used to set the maximum current range of the CURRENT CON- TROL on the TIG Module.

13. 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 14 - 17)

14. 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 section in the installation chapter for further information about this receptacle. Also refer to the AUXILIARY POWER OPERATION section later in this chapter.
