torch -- RED 9Main power supply switch, 0 / 1 / START
2Connection with water lock for cooling wa-
ter to the TIG torch -- BLUE 10 White indicating lamp -- Power supply ON
3Cooling water filler 11 Orange indicating lamp -- Overheating
4Connection for return cable (+) 12 Control panel
(see the respective instructions)
5Connection for remote control 13 Fuse4AT
6Connection for welding cable (--) 14 Connection for gas hose
7Connection for start signal from the wel-
ding torch 15 Connection for cooling water. Not used on this model.
8Connection for gas to the TIG torch 16 Connection for cooling water. Not used on
this model.
6.2 Turning on the power source
Turn on the mains power by turning switch (9) to the ”START” position. Release the
switch, and it will return to the ”1” position.
If the mains power supply should be interrupted while welding is in progress, and
then be restored, the power source will remain de--energised until the switch is again
turned manually to the ”START” position.
Turn the unit off by turning the switch to the ”0” position
Whether in the event of a loss of power supply or of turning the power source off in
the normal manner, welding data will be stored so that it is available next time the
unit is started.
