1
st
cycle:
• Press and hold torch trigger 1.
• The gas pre-flow time
expires (shielding gas flows).
• The arc is ignited (HF ignition).
• The start current
flows for the start time
(the HF ignition shuts down).
• The welding current increases in the up-slope time
to the main current
.
2
nd
cycle:
• Release torch trigger 1.
• The main current
drops during the down-slope time
to the end current
.
When the 1st torch trigger is pressed during the down-slope time
, the current increases back to
the main current
.
• The end current
flows for the end current time
.
• The arc extinguishes.
• The gas post-flow time
expires (the shielding gas is shut down).
