3.2.5 remote control memory channels
Memory channels are selected by pressing simultaneously both REMOTE and CH button. With
the remote control you can retrieve saved settings on memory channels 1-5. The selected
channel is marked with a dot.
3.2.6 seTup functions
A so called SETUP state is included for modifying panel functions. You can enter the SETUP

3.2.7 Foot pedal control r11F
First read "ACS Welding Panel – Basic Functions" point "Remote control" for installing the
remote control ready for operation. Foot pedal R11F is used in TIG welding, and its control
range is adjustable. The minimum value of control range is set with the panel potentiometer
when the pedal is not pressed, display shows "LO". Control range maximum is set similarly by
pressing first the PEDAL LO/HI button on the panel, display shows "HI". Welding is started with

The operation of Mastercool cooling unit is controlled by the power source. The cooling unit
pump starts automatically when welding starts. Proceed as follows:
1.
Start power source.
2.
Check water level and input flow of the reservoir, add liquid if needed.
3.
If you use a water-cooled torch you can fill it with water by pressing WATER FILL button for
more than 2 seconds.
The pump operates for 4 another minutes after welding has been finished to cool the water to
the same temperature as in the machine surrounds. This reduces the need of service.
Thermal overload
The thermal overload light is lit, the machine stops and display shows COOLER when
temperature control of the machine has detected cooling water overheating. The cooling unit
fan cools down the water, and when the light goes out welding can be started again.
water flow signal
