10 Start-up / drainage
Before connecting the unit to the welding power source, check the rating plate and make sure the voltage
and frequency of the main power correspond.
Check that the main circuit breaker on the equipment is turned to “O”.
Upon the first usage following a period of extended inactivity of the cooling unit or in the case in which the
electro pump does not go under pressure (slight whistle), it is necessary to undertake drainage in order to
eliminate all the air bubbles present within the hydraulic circuit.
Carry out the following operations following the assembly instructions indicated here (Image 3) and also
contained in the accessories packet:
A) Unscrew the tank’s cap and, using a funnel, fill it with distilled water. In case of particularly rigid climates
with air temperature near to 0° C it is necessary to add antifreeze to the cooling distilled water. Do not use
antifreeze containing propylene because it could provoke blockage of the electro pump.
B) Connect the tube provided to the blue rapid mount and insert the other end of the tube into the tank.
C) Start up the welder by rotating the main switch to the 1 position and wait approximately 30 seconds so that the
cooling device can allow the liquid to circulate.
D) Wait for the exit of the liquid. The operation will be terminated when the liquid exits in a constant way and
without any traces of air bubbles.
E) Upon the completion of the operation, turn the welder off.
F) After that, screw the tank’s cap shut and connect the welder prior to beginning operation.
