8.2
Usage of the cooling unit
IMPORTANT! Turn OFF the cooling unit when welding MMA or using air cooled
MIG/TIG welding guns to avoid excessive wear of the pump. Otherwise the pump will
work against a closed valve.
Turn ON the cooling unit when using a water cooled MIG welding gun to avoid
damages on the cable set.
8.3
Cooling unit connection
For problem-free operation it is recommended that the height from the cooling unit to
the water-cooled GMAW (MIG/MAG) torch is a maximum of 8.5 m.
8.4
Coolant pressure controller
The pump has an enclosed pressure relief valve. The valve opens gradually when the
pressure is too high. This can occur if a hose is folded, which makes the flow fail or
stop.

MAINTENANCE
Regular maintenance is important for safe, reliable operation.
Only those persons who have appropriate electrical knowledge (authorized
personnel) may remove the safety plates.
Supplier warranty is void if customer attempts any work on product during the
warranty period.
9.1
Inspection and cleaning
WARNING
The mains supply must be disconnected before cleaning.
Dust, grinding swarf, etc. The air stream through the cooling unit carries particles
that become trapped in the cooling element, particularly in dirty working
environments. This results in reduced cooling capacity. For this reason, blow clean
using compressed air at regular intervals.
Coolant system - Only the recommended coolant must be used in the system,
otherwise clumps can be created that block the pump, water connections, or
elements. Flushing can only be performed via the red water connection. Then drain
the tank manually, i.e. empty via the tank's filling hole.
