DIP Switch 5: Low OCV Enable
This controls the OCV of the machine. When the DIP switch is OFF the OCV is set to the normal level as stated in the manuals for the machines. When the DIP switch is ON the OCV is reduced to 20V. This low OCV mode was created for the Australian markets and should only be used as required by these Australian specifications. The low OCV will somewhat reduce the starting performance of the machine when dirt, rust, and/or slag is present on the work piece.
DIP Switch 6: European/USA Machine Configuration
This configures several functions of the V160 as required by the European and USA markets. For the European market it is OFF and for the USA market it is ON.
Specifically, this configures the operation of the TIG slope timers, remote control, and trigger. However, this configuration also depends on the position of DIP Switch 1 which selects the machine type. This setting can be changed but only if the following func- tions are clearly understood.
(DIP Switch 1 = OFF)
In TIG welding mode, the following conditions can exist.
•European Machine Configuration (DIP Switch 6 = OFF)
The TIG slope functions are always enabled. After the arc is started the output current will be increased (upslope) to the welding current. At the end of the weld the current will be decreased with the downs- lope function. Using a "foot pedal" remote control is not recommended with this setup.
A trigger is always needed to turn ON the output of the machine.
•USA Machine Configuration (DIP Switch 6 = ON) The TIG slope functions depends on the possible connection of a remote control.
•No remote control connected. The TIG slope func- tions are enabled. After the arc is started the output current will be increased (upslope) to the welding current. At the end of the weld the current will be decreased with the downslope function.
•Remote control connected. The TIG slope functions are disabled for the 2 step trigger mode. If slopes are needed a foot pedal remote control can be used. The TIG slope functions are enabled for the 4 step trigger mode.
A trigger is always needed to turn ON the output of the machine.
