4.3. PREPARING THE WELDING UNIT FOR OPERATION TIG – 2T
4.3.1 OPERATIONAL CYCLE OF THE WELDING PROCESS WITH TIG-2T
FUNCTION
The procedure for changing the values of the operational parameters of the welding unit is described in
Section 6.1.
The procedure for preparing the welding unit for operation with an external oscillator is an individual
one and should be described in the oscillator operation manual. The connector for remote switching on
and off the welding unit is located on the rear panel of the welding unit. Use only contacts 1 and 2 of
the connector. Do not confuse contacts 1 and 2 with contacts 3 and 4, as these contacts are designed
for powering the electrode wire feeding unit. When contacts 3 and 4 are cross-circuited, the electrode
wire feeding unit will be damaged.
ATTENTION!
If this connector is not used, cover it in order to prevent
contamination.
