Select Demo, 2-function switch operation and continuous welding S24.

Adjust welding current with parallel control S29, or go over to adjustment for welding

current with arrow keys S27 and adjust current with +/- keys S28. Reading will be visible

in display P23.

Go with arrow keys S27 to pre-gas point H21. Adjust pre-gas time P21 with +/- keys S28.

Go to up-slope point of current H24. Adjust up-slope time P22 with keys +/-.

Go to down-slope point of current H24. Adjust down-slope time P24 with +/- keys.

Go to post gas point H25. Adjust post gas time P25 with +/- keys.

By pressing the torch switch you can go through the whole operation cycle and after that go

to welding by selecting the ignition mode. You can use as operation models of torch switch

also the 4-function and Minilog operations.
Note the up- and down-slope times changing with current control and adjust when necessary.
If arc is not ignited within 4 sec from start, the unit will automatically go to stop without

timing.
Values of up- and down-slope times change automatically, when set values of welding current

are changing. Due to automatics you don`t need to change times in many welding cases,

when you change current.

Select TIG welding, Demo, 2-function switch operation and pulsed welding S24.

Adjust welding parameters as above in point: ”Controls for continuous welding”.

Automatics of unit set pulse parameters automatically according to start values in

storage. Automatics of unit calculate a new average value for current, when pulse values

are changed. Automatics make the operations in that way easier that you need not

always adjust again other parameters of pulse, when pulse or mean current value is

changed.

Adjust pulse values in turns by going with arrow keys S27 to required adjustment point:

pulse current H31, pulse ratio H32, cycle time H33 and pause current H34. Control values

can be seen in display P31.
