7.2.5
TIG 2-Stroke Liftarc
In this mode, the ignitor is switched off. This operating mode can not
be used with AC welding (TIG 500AC only), as with AC, the ignitor is
also required for welding.
1. Stroke
The tungsten electrode must touch the workpiece.
Press and hold the torch button. After expiration of the gas pre-flow
time and lifting of the TIG electrode, the arc ignites. The welding
current increases to the value I1 with the time set on the soft start
rotary knob. The welding current I1 can be adjusted continuously on
the rotary knob I1.
2. Stroke
Open torch button. The welding current drops to minimum with the
time set on the soft-down rotary knob. The arc goes out. The shielding
gas flows during the set gas post-flow time.
7.2.6
TIG 4-Stroke Pulse with HF
1. Stroke
Press and hold the torch button. When the gas pre-flow time has
elapsed, the arc ignites at 20% of I1 (search arc).
2. Stroke
Open torch button. The welding current rises to the set value of I1. The
arc is pulsing. The welding current 1 can be adjusted continuously on
the rotary knob I1. The welding current 2 can be adjusted continuously
on the rotary knob I2, as a percentage of I1. The rotary knob t1 is used
to select the pulse time for I1 and the rotary knob t2 for the pulse time
for I2.
The pulse times are adjustable from 20 ms to 1.3 s.
3. Stroke
Press and hold the torch button. The welding current decreases to the
minimum current during the set time.
4. Stroke
Open torch button. The arc goes out.
The shielding gas flows during the set gas post-flow time.
7.2.7
TIG 2-Stroke Pulse with HF
1. Stroke
Press and hold the torch button. After expiration of the gas pre-flow
time the arc ignites. The welding current increases to the value I1 with
the time set on the soft-start rotary knob. The welding current I1 can
be adjusted continuously on the rotary knob I1. The welding current 2
can be adjusted continuously on the rotary knob I2, as a percentage of
I1. The rotary knob t1 is used to select the pulse time for I1 and the
rotary knob t2 for the pulse time for I2.
