THE ART OF WELDING
5. 4. 6. Manual weld cycle stop
5. 4. 6. 1. Manual weld cycle stop with downslope
The manual downslope button BT 6 on the remote
control pendant starts the programmed downslope
sequence. This function provides the workpiece as
much as possible from being damaged. The indicator
will fl ash because this is not a regular cycle end.

5. 4. 6. 2. Immediate cycle stop
When the stop button BT 7 of the remote control
pendant is pressed, the arc and all movements are
stopped immediately. The shielding gas is main-
tained during the programmed post gas period T25.
The indicator will fl ash because this is not a regular
cycle end.
5. 4. 6. 3. Emergency stop
The remote control pendant is fi tted with an emer-
gency button BT 2. By pressing this button, the
PS 164-2 is immediately disconnected from the
mains power supply. The weld, the movements and
the gas fl ow are stopped suddenly.
This function may cause serious damages
to the workpiece and equipment. Polysoude
advises you, if possible, to choose a stop with
the downslope button or with the immediate
stop button.
5. 4. 6. 4. Using a manual welding torch
You should introduce a short program with both a
high and a low current when welding with a manual
torch as described in paragraph 4.3.6.
The arc is struck by pressing the manual command
button. The weld current value is equal to the pro-
grammed ignition current. If you release this button,
the high current value I22 is applied. If you press
this button again, the low current I23 will be used.
The next release restarts the high current and so
on. The cycle stop is made either by pressing on the
downslope button, or for an immediate cycle stop,
by pressing on both ends of the manual command
button.
5. 5. lternating use of at two welding stations
on the same workpiece
In the case of alternating use of
at least two welding stations on
the same workpiece, make sure
the welding head motor covers
do not come into contact with
the workpiece potential.
These parts of the head are
connected to metal earth by the
shielding of the auxiliary cables.
Neglecting to connect the ear-
thing cable (+) on certain ma-
nual stations can lead to destruc-
tion of the welding head motor
control cable.
