All information relates to the total hose package length of the complete welding system and presents exemplary configurations (of components of the EWM product portfolio with standard lengths). A straight kink-free installation is to be ensured, taking into account the max. delivery height.
Design and function Transport and installation 5.2.3.4 Adding coolant After switching on the machine, the coolant pump runs for a defined time (filling the hose package). If the machine does not detect sufficient coolant flow during this time, the coolant pump is switched off (protec- tion against damage caused by dry running).
Coolant line connections 5.2.4.1 Cool 55 U40; Cool 55 U42 The cooling circuit (cooling unit <> welding torch) must not be interrupted. Otherwise, the coo- lant pump can be destroyed by thermal overload (the coolant cannot circulate). When using air-...

Maintenance, care and disposal General Maintenance, care and disposal General WARNING Improper maintenance, testing and repairs! Maintenance, testing and repair of the machine may only be carried out by skilled and qualified personnel (authorised service personnel). A competent person is someone who, based on training, knowledge and experience, can recognize the hazards and pos- sible consequential damage that may occur when testing power sources and can take the necessary safety precautions.
Maintenance, care and disposal Maintenance schedule Maintenance schedule Maintenance step Only personnel designated as inspectors or repairers due to their trai- ning are allowed to carry out the relevant work step! Inapplicable checkpoints are omitted. • Check and clean the welding torch. Deposits in the welding torch may cause short circuits, impair the welding result and lead to welding torch damage! •...
Maintenance, care and disposal Maintenance schedule 6.3.1 Coolant error Figure 6-1 • Switch off the machine and disconnect the mains plug. Position a suitable collecting container under the drain plug of the coolant tank. • Unscrew the drain plug of the coolant tank (remove the tank cap to ventilate). Figure 6-2 •...
Insert the cleaned filter screen into the filler neck and screw the drain plug with seal back into the tank. • Fill the tank with original EWM coolant up to the maximum level. After filling, refit the tank cap and vent the coolant circuit > see 5.2.3.4 chapter.
A periodic test according to IEC 60974-4 "Periodic inspection and test" has to be carried out. In addition to the regulations on testing given here, the relevant local laws and regulations must also be observed.
