TIG pulses, function sequences

The machines have an integrated TIG pulse device as standard.
Entering the pulse parameters:
•
Pulse current = main current AMP,
•
Break current = secondary current AMP%.
The times for the pulse and break current are pre-set at 0.3 sec ex works and can be
changed internally (see Chap. 3.9.5)
TIG pulses can also be realized with the pulse remote controls RTP1 and RTP2.
The function sequences of TIG pulses are principally the same as for standard TIG welding.
As soon as the arc has ignited, the current switches to and from between the pulse current
and pause current with particular times.
When the foot-operated remote control RTF is connected, the machine switches
automatically to non-latched operation. The Up- and Down-slopes are switched off.
See the explanation of symbols under Chap. 3.3.1.
