2.12 OPERATION OF COOLING UNIT, FASTCOOL 10
Operation of cooling unit is controlled in such a way that pump is started when welding is
started. After welding stop pump is rotating for approx. 5 min cooling the gun and the cooling
liquid to ambient temperature.
Read in operation instructions for the Fastcool 10 unit the trouble situations of the liquid
circulation system and protection against torch etc. damage.
2.13 HANGING
MSF 53 needs hanging frame (accessorie) for mounting, do not hang from the handle. MSF 55
and MSF 57 can be hanged from hanging kit available as an accessorie.

Main switch, ON/OFF (1)
The wire feed unit remains in the OFF position when the power source is switched on, thus
preventing start-up. 'OFF' is shown on the display.
When the ON/OFF button is pressed for more than 1 second, the unit starts up. The unit is now
ready for welding and will automatically return back to it previous position, before the power
was cut off. The wire feed unit starts up also by pressing three (short) times the switch of the
welding gun.
Basic settings and displays (11, 12, 2, 8)
The wire feed speed is set via potentiometer (11), the value of which is shown on display (2).
The welding voltage is set via potentiometer (12), the value of which is shown on display (8).
During welding, display (2) shows the actual welding current value and display (8) shows
welding voltage.
When MIG dynamics adjustment is activated via button (3), the MIG dynamics value is
adjusted through potentiometer (12) (see 'Adjustment of MIG dynamics').
With electrode welding (MMA), the welding current value is set via the potentiometer, the
value of which is shown on display (2). Display (8) shows the idling voltage of the power
source. During welding, display (2) shows the actual welding current value and display (8)
shows the welding voltage.
