5 OPERATION
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 SMAW or using air cooled
GMAW/GTAW 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 GMAW welding torch to avoid
damage to 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 GMAW 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.

6 MAINTENANCE
6 MAINTENANCE
NOTE!
Regular maintenance is important for safe and reliable operation.
CAUTION!
Only persons with appropriate electrical knowledge (authorized personnel) may
remove the safety plates.
CAUTION!
All warranty undertakings from the supplier cease to apply if the customer attempts
any work to rectify any faults in the product during the warranty period.
6.1 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.
The coolant system
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.
6.2 Filling with coolant
Only use ESAB's ready mixed coolant, see the "ACCESSORIES" chapter.
• Fill with coolant. (The fluid level must
not exceed the upper marking but
neither must it be below the lower
marking.)
NOTE!
Coolant must be topped up if connecting a welding torch or coolant hoses that are 5
meters in length or longer. When adjusting the water level by topping up, the coolant
hoses do not need to be disconnected.
CAUTION!
The coolant must be handled as chemical waste.
