5 OPERATION
General safety regulations for handling the equipment can be found in the "SAFETY"
chapter of this manual. Read it through before you start using the equipment!
5.1 Connections and control devices
1. Switch for On/Off
2. Coolant filling
3. Min/max of coolant
4. Connection RED for coolant (return) to
cooling unit
5. Connection BLUE for coolant from
cooling unit
5.2 Usage of the cooling unit
CAUTION!
Important!
Turn OFF the cooling unit when welding MMA or using air cooled
MIG/TIG welding torches 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 torch to avoid
damages on the cable set.
5.3 Coolant connection
For problem free operation it is recommended that the height from the cooling unit to the
water-cooled MIG/MAG torch is a maximum of 8.5 m.
5.4 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 causes the flow to fail or stop.
