- (
2-step welding
) It is necessary to keep digital input ON for the whole
process of welding. Releasing the input will stop the process and bring the controller
to
ready state
. A new welding will be triggered only from
ready state
of the
controller, i.e. previous welding finished and digital input OFF:
3
- (
Continuous mode
) In this mode the welding process continues without
sparks with output power of
SP
. Releasing the input will stop the weld and finish the
cooling phase of the process. A new welding will be triggered only from
ready state
of the controller, i.e. previous welding finished and digital input OFF:
*
When in
continuous welding mode
with the digital input ON, the display will
show the current output power
SP
,
that can be changed directly by the arrow keys.
This helps the user find the suitable values in this welding mode, especially in the
process of seam sealing.
