Preparation of the welding pliers

WARNING! Risk of injury from sudden release of the welding tool!
When changing a tool with the machine switched on, welding current or pliers move-
ments can be accidentally triggered. Risk of crushing. Therefore:
– First prepare the welding pliers/welding gun and then switch on the machine.
– If tool changing is necessary during work, be sure to switch off the machine first.
ATTENTION!
Switch off the coolant pump before changing the electrode arm.
Risk of scalding
CAUTION! Risk of scalding from escaping hot water!
Hot water can splash out when disconnecting the coolant hoses. Therefore:
– Wear protective gloves.
– Pull off the coolant hoses carefully.
Risk of slipping
CAUTION! Risk of slipping due to escaping water!
Water can splash out when disconnecting the coolant hoses. Therefore:
– Wipe up any water on the floor.
The device switches automatically to the correct pliers symbol.
Place the electrode arm into the pliers (s. 5.1.3.1).
Lock in movable electrode arm.
Adjust distance of electrodes between 6 and 8 mm (s. 5.1.3.4).
Tighten the hexagon screw.
After the first welds check again the distance of the electrodes and adjust, if neces-
sary!
