Ignition monitoring:
If, after fruitless attempts to ignite an arc or after an arc-interrupt,
the welder forgets to stop the control sequence (2-step or 4-step)
by means of the torch trigger, the shielding gas will continue to flow,
leading to considerable wastage of gas. To prevent this, a moni-
toring function automatically interrupts the control sequence after
approx. 5 sec. in such a case. When another attempt is made to
ignite an arc, this must once again be initiated via the torch trigger.
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.

- Pre-select the type of current with the current-type selector
switch (only on MW 2600 / 2600CEL / 3000)
- In AC~ mode: Set the balance and AC frequency
(only on MW 2600 / 2600CEL / 3000)
- If necessary, connect a remote control unit
- Select welding parameters (command value for main current I

- Open the gas cylinder valve by turning it anticlockwise.
- Press gas-test button on the rear of the machine, and set the
required gas flow rate
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 MW2600 / 2600CEL
- Activate the synchronous welding function
- Switch on the mains master switch
- Enter in program level 3
(see p.13 "Working with the program levels")
Warning! At both units the phase sequence must be synchro-
nized!
