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, align and tighten (see 5.1.3.1). 

 

Align the electrodes (see 5.1.3.3). 

 

Tighten the electrode clamping screw.

Fig.6: Replacement of the elec-
trode arm 

 

1. Loosen the electrode arm at the knob (Fig. 6). 

2. Press in the ring of the water plug connector  
    and hold depressed. 
3. Pull the coolant line out of the plug connector. 
4. After disconnecting the coolant lines, loosen the knob of the C-arm 

and pull the C-arm off the pliers by turning the arm so that the pins 
of the C-arm are aligned with the grooves in the pliers. 

5. Push the new C-arm onto the pliers, align vertically and tighten the 

knob of the C-arm. 

6. Push the coolant lines into the plug connectors.

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.
