TIG WELDING WITH CONTACT IGNITION
(WITHOUT HF)
START UP
- Fit the torch with a tungsten electrode and a gas nozzle
(see the instruction manual for the torch concerned).
- Plug the earth cable into the current socket and latch in place
firmly.
- Connect the gas hose to the machine and the gas press.

Igniting the arc:
- Make sure the welding current is switched off. Place the
electrode on the weld at the point where the arc is to be ignited,
tilt the torch backwards until the edge of the gas nozzle is
resting on the workpiece, leaving a gap of between 2 and 3 mm
between the tip of the electrode and the workpiece. Fig. 25a
- Close your visor.
- Switch on the welding current with the torch trigger - shielding
gas starts flowing
- Resting the torch on the edge of the nozzle, gradually tilt it
upwards until the tip of the electrode touches the workpiece.

TIG SYNCHRONOUS WELDING AC

- Only possible at MW 2600 / 2600 CEL
- Activate the synchronous welding function
- Switch on the mains master switch
- Enter in program level 3
(see "Working with the program levels")
Note! At both units the phase sequence must be syn-
chronized!
