NOTE
The applicable accident prevention and safety regulations have to be complied with
when operating the stud welder.
NOTE
The welding points must be free from rust/scale.
→ Grind welding positions if necessary.
6.1.1

Accumulator operation

• Briefly press on/off switch.
When switching the stud welder on, all LED displays light up briefly on the front panel to check proper
operation.
Caution: The stud welder is ready for welding in about 20 seconds after the welding capacitor has
been charged. This period of time can be used e.g. to insert the welding stud into the stud holder. By
lightning up, the LED "Ready" indicates that the stud welder is ready for welding.
• Position PS-0DV stud welding gun with welding stud on the workpiece.
The LED "Stud on workpiece" lights up.
Keep the gun still and preferably at an angle of 90° to the welding surface.
• Press gun switch. The LED "Release" lights up. The welding process is effected immediately.
• After having completed the welding process, remove the gun evenly from the welding stud in a
straight line motion. After the welding gun has been removed from the stud, the capacitor is
recharged.
An acoustic warning signal announces that the accumulator is about to be discharged. When the
accumulator has been discharged, the stud welder is blocked and the capacitor prevented from being
recharged.

When the accumulator is discharged or its capacity is below 20%, you may also operate
the stud welder with the connected battery charger.
"Standby" function with accumulator operation
If the stud welder is not used within 5 minutes after it has been switched on, it will automatically be
switched to the "Standby" function. All displays are switched off and the stud welder is no longer ready
for welding. The LED "Supply voltage on" starts blinking (item 1.4, chapter 5.2.2). As the current
consumption is very low now, the stud welder can remain switched on for a longer period of time. The
stud welder is ready for welding again when pressing the trigger switch of the welding gun. The stud
welder will automatically be switched off after 10 minutes in the standby operation. The stud welder is
operative again when briefly pressing the on/off switch.
