Electrode welding process

 Select the electrode welding process with button 30 (LED
electrode- DC 33 or LED electrode- AC 34 lights up).
9 You are in the parameter main current I1 (LED Main current
I1 37 lights up).
 Use the rotary knob 41 to set the desired current intensity.
9 Your welding machine is now ready for use.

Tab. 1: Main parameters
The factory setting values are optimised thanks to automatic
parameters.
You can use these factory settings unchanged for most weld-
ing jobs.
Further fine adjustment facilities can be found in Chapter „14.3
Secondary parameters" on page 39.

TIG welding process

 Select the TIG welding process with button 30 (LED TIG-
DC 31 or LED TIG- AC 32 lights up).
 Select the desired mode with button 47 (LED 2-stroke 44,
LED 4-stroke 45 or LED Pulse 46 lights up).
 48 Press the main parameter button on the bottom right
until the desired parameter appears (the corresponding
LED 35 - 43 lights up).
 Use knob 41 to set the desired value.
9 Your welding machine is now ready for use.
