WARNING! If the power source is plugged into the mains electricity during
installation, there is a high risk of very serious injury an damage. Before
putting the machine into service, read the section headed „Safety rules“. Only
carry ut these preparations if
- the mains switch is in the - O - positionn and
- the mains cable is unplugged from the mains.
WARNING! Operating the equipment incorrectly can cause serious injury and
damage. Do not use the functions described here until you have read and
completely understood all of the following documents:
- these Operating Instructions
- all operating instructions for the system components, especially the
“Safety rules”
CAUTION! As soon as the process “TIG welding” is selected, the tungsten
electrode of the TIG welding torch is live. Make sure that the tungsten electro-
de is not touching any electrically conductive or earthed parts such as e.g. the
workpiece or housing.
General remarks
1. Shift the mains switch (8) into the - I - position (all the indicators on the control
panel briefly light up)
2. Use the Process button (3) to select the process “TIG welding” - the welding
voltage to the welding socket is switched on after a 3 s time-lag.
TIG welding
1. Shift the mains switch (8) into the - O - position
2. Unplug the machine from the mains
3. Dismount the welding potential cable
4. Plug the earth cable into the current socket (B) and latch it in firmly
5. Connect the other end of the earth cable to the workpiece
6. Plug the welding cable of the TIG gas-valve welding torch into the current socket (-)
(A) and latch it by turning it clockwise
7. Screw the pressure regulator onto the argon shielding-gas cylinder and tighten it
8. Attach the gas hose to the pressure regulator
9. Plug the machine back into the mains
NOTE! Parameters that can be set on the remote-control unit TR 2000 / 3000 /
4000 cannot be changed on the power source. Parameter changes can only
be made on the remote-control unit TR 2000 / 3000 / 4000.
3. Press the Parameter Selection button (2)(indicator on the button must light up)
4. Set the desired amperage, using the adjusting dial (1) (value can be read off from
the left-hand indicator)
5. Open the gas cut-off valve on the TIG gas-valve torch and set the desired shiel-
ding-gas flow rate on the pressure regulator
NOTE! Ignition of the welding arc is effected by touching down the tungsten
electrode onto the workpiece.
