TIG welding

Safety

Danger from incorrect operation.
Operating the equipment incorrectly can cause serious injury and damage.
▶
▶
Risk of electric shock.
An electric shock can be fatal. If the device is plugged into the mains during in-
stallation, there is a high risk of serious injury and damage to property.

WARNING!
Do not use the functions described here until you have read and completely
understood these Operating Instructions.
Do not use the functions described here until you have fully read and un-
derstood all of the Operating Instructions for the system components, in
particular the safety rules.
WARNING!
Only carry out work on the device if the mains switch is in the "O" position.
Only carry out work on the charger when it has been disconnected from the
mains supply.
WARNING!
As soon as the mains switch is in the "I" position, the tungsten electrode of
the welding torch is live. Ensure that the tungsten electrode does not touch
any persons or electrically conductive or earthed parts (e.g. housing, etc.).
Move the mains switch (8) to the "I" position (all the indicators on the control
panel will briefly light up)
Using the Process button (3), select the TIG welding process - the welding
voltage is applied to the welding socket with a 3 s time lag.
Press the "Parameter selection" button (2) (indicator on the button must light
up)
- Parameters which can be adjusted on the TR 2000 / 3000 / 4000 remote
control cannot be altered on the power source. These parameters can on-
ly be altered on the TR 2000 / 3000 / 4000 remote control.
Set the desired amperage using the adjusting dial (1) (value can be read off
from the left-hand indicator)
Open the gas shut-off valve on the TIG gas-valve torch and set the required
shielding gas flow rate on the pressure regulator.
Place the gas nozzle on the ignition location so that there is a gap of 2 - 3 mm
(a) between the tungsten electrode and the workpiece
Gradually tilt the welding torch up until the tungsten electrode touches the
workpiece (b)
