5 OPERATION
5.1 General
General safety regulations for handling the equipment can be found in the "SAFETY"
chapter of this manual and the "SAFETY" chapter of the manual for the power source.
Read it through before you start using the equipment!
Cooling unit EC1000 automatically starts when welding starts. After welding has stopped,
cooling continues for a few minutes after which the cooling unit enters energy save mode.
5.2 Connections and control devices
1. Connection BLUE for coolant from cooling
unit
3. Coolant filling
2. Connection RED for coolant (return) to
cooling unit
4. Connection to power source (interface
cable)
5.3 Coolant connection
For problem free operation it is recommended that the height from the cooling unit to the
water-cooled TIG torch is a maximum of 8 m. When connecting a TIG torch it should be in
the same height as the cooling unit to let the coolant quickly spread through the system.
NOTE!
After connecting a torch, check that the coolant level is correct. When adjusting
the coolant level by topping up, the coolant hoses do not need to be
disconnected.
5.4 ELP (ESAB Logic Pump)
The cooling unit is equipped with a detection system called ELP (ESAB Logic Pump) which
checks that the coolant hoses are connected. When connecting a water-cooled TIG torch,
cooling starts.

5.5 Control of the cooling fan and the water pump
Cooling unit EC1000 is equipped with a thermal sensor to monitor the temperature of the
cooling liquid and facilitate control of the cooling unit functionality. The function of the cooling
unit is as follows:
• When welding starts, the cooling fan and the water pump automatically starts.
• If the cooling liquid temperature exceeds +45°C (+113°F), the cooling fan and the
water pump starts, even though no welding is going on.
• If the cooling liquid temperature is below +45°C (+113°F) and welding stops, the
cooling fan and the water pump continue running for 3 minutes to speed up cooling of
the equipment. After 3 minutes the cooling fan and the water pump stop.
• If the cooling liquid temperature is +45°C (+113°F) or more and welding stops, the
cooling fan and the water pump continue running to speed up cooling of the
equipment. When the cooling liquid temperature has decreased below +35°C
(+95°F), the fan and the pump proceed for 3 minutes more after which they stop. If
the cooling liquid temperature has not decreased below +35°C (+95°F) within 7
minutes after welding has stopped (due to high ambient temperature), the fan and the
pump proceed for 3 minutes more after which they will stop anyway. This means that
the fan and the pump will stop maximum 10 minutes after welding has stopped,
regardless of the cooling liquid temperature.
• If the cooling liquid temperature exceeds +65°C (+149°F), a thermal protection
function automatically stops the welding, error code "Err2" appears in the power
source display and the overheating indicator on the display is lit. The cooling fan and
the water pump will continue running. When the cooling liquid temperature has
decreased below +55°C (+131°F), error code "Err2" is cleared and the overheating
indicator on the display goes out. Finally, when the cooling liquid temperature has
decreased below +35°C (+95°F), the fan and the pump proceed for 3minutes more
after which they stop. If the cooling liquid temperature has not decreased below
+35°C (+95°F) within 10 minutes after welding has stopped (due to high ambient
temperature), the fan and the pump will stop anyway.
5.6 Coolant pressure controller
The pump is equipped with a mechanical pressure relief valve. The valve opens gradually
when the pressure is too high (4.8bar/ 70psi). This can occur if a hose is folded, which
causes the flow to fail or stop.

6 MAINTENANCE
NOTE!
Regular maintenance is important for safe and reliable operation.
CAUTION!
Only those persons who have 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
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.
In order to sustain the performance and increase the lifetime of the cooling unit, it is
mandatory to clean it using compressed air at regular intervals. How often depends on:
• The welding process
• The arc time
• The surrounding environment (grinding etc.)
Equipment and prerequisites
• Screwdrivers, Torx T25 and T30
• Dry compressed air, at a pressure of 4bar (58psi)
• Recommended personal safety equipment, such as ear plugs, safety glasses, masks,
gloves and safety shoes
• The cleaning should be carried out in a suitably prepared workspace.
