13.1 Electrode welding process
Switch on machine
 Turn on the machine at mains switch 9.
 Press key button 44 for at least 2 seconds.
9 Symbol Electrode (LED 34) lights up.
 Press key button 44 again to turn the pulsing function on
or off.
 Set the required welding current with turning knob 45.

Ignition
 Touch the workpiece with the tip of the electrode and lift
the electrode a bit.
9 The arc ignites between the workpiece and electrode.
Pulse
 Press key button 44 until the symbol for pulsing lights up
(LED36).
 Access the secondary parameter (refer to the subchapter:
accessing secondary parameter).
 Select secondary parameter secondary current I2
(Code „I 2").
 Set the required secondary power value with turning knob
45. The adjusted value is based in % from welding current
I1.
 Select the secondary parameter pulse frequence (Code
„FPU").
 Set the required pulse frequence with turning knob 45.
 Select secondary parameter pulse pause ratio (Code
„bPU").
 Set the required pulse pause ratio with turnng knob 27.
The adjusted value is based in % from welding current I1.
Example: 60% equates to 60% welding current I1 and 40%
secondary current I2.
 Exit secondary parameter.

13.2 TIG welding process
Danger due to electric shock!
If function HF-ignition is selected, a high ig-
nition voltage is present at the torch.
Never touch the welding electrode or parts
conducting welding current when the de-
vice is switched on.
Switch on machine
 Turn on the machine at mains switch 9.
 Press key button 40 to set TIG mode and for changing bet-
ween 2-stroke and 4-stroke mode.
9 Symbol TIG (LED 37) and 2-stroke (LED 38) or 4-stroke (LED
39) light up.
 Press repeatedly key 44 to switch function Slope as well as
pulsing either on or off.
 Set the required welding current with turning knob 45.

Ignition
 Hold the electrode of the Tig torch close above the workpi-
ece and ignite the arc by pressing key button 75.
9 Arc burns between work workpiece and electrode.
‰ By set secondary parameter HF-ignition OFF, the workpi-
ece must shortly be touched with the electrode of the Tig
torch.
