27. Initial Operation and welding
Installation of the welding machine
When installing the machine, make sure that there is sufficient space for inlet and outlet cooling air so that
the rated duty cycle will be attained.
The machine should not be exposed to moisture, welding spatter or spark rays caused by grinding work.
The welding inverter should not be operated in the rain.
TIG welding:
Connection of shielding gas cylinder
Connect cylinder pressure reducer and Check that all connections are tightly sealed.
Connection of the torch
Connect the power cable in – tip jack and gas hose into the gas nipple.
Insert the torch trigger (and optional up / down buttons) cable in the 5-pole Tuchel connector plug
(see circuit diagram).
Setting of cylinder pressure reducer
Set the shielding gas flow rate at the pressure reducer on cylinder. The gas flow rate depends chiefly on the
welding amperage.
Connection of work piece cable
When clamping the work piece into its holder, choose appropriate spot without paint or rust for good
conductivity.
In TIG welding, the work piece cable has to be connected to the “+” tip jack.
Ensure excellent contact between all connections within the welding circuit,
i.e. work piece, torch connection and contact tip nozzle. Bad contact causes high transi-
tion resistance which leads to overheating and poor quality of the weld.
Adjust all welding parameters
The settings are made with the help of Chapter 21.
