Welding Torch Cooling / Coolant Jpp; Maintenance And Safety Check - Jackle conMIG 445 Betriebsanleitung

37. Welding torch cooling / coolant JPP

Maximum pressure: 3,2bar
Way of functioning
The circulation water cooling is based on the function of a recooling plant: the cooling liquid is cooled down to
approximately room temperature via heat exchanger, with the help of the room air which is circulated by the fan.
Water-cooled torch
The torch is cooled by a built-in low-noise, pump operated, water-cooling system. The water tank should be kept
almost full. In case of loss of water due to exchange of torch or hose sections, Check water level in the tank.
Water flow monitoring
In cooling water and flow deficiency (less than 0.25 l / min), a sensor turns off the control and display the error
message ‚ Err H2o ---‚.
After the cause is corrected for the water deficiency, the machine must switch off and on.
Water flow test
By pressing the button l/min, the water pump is activated, while the right display shows the current water flow
rate (e.g., 1.15 L / min).
If the value is less than 0.25 l/min, an insufficient water flow is present, and after 5 seconds, the pump is turned
off automatically. Troubleshooting Chapter 34 – error.
- ONLY use JÄCKLE coolant JPP (Order No. 900.020.400)
- Unsuitable coolants can cause property damage and loss of warranty.
- Do not mix with water or other coolant.
- Do not weld without cooling water! Tank must always be full.
- Pump must not run dry, not even for a short time. Deaerating the pump.
- Hazardous to health – keep away from children!
MATERIAL SAFETY DATA on
- Frost-resistance up to -30°C

38. Maintenance and safety check

The welding unit is, on principle, maintenance-free. However, make it a rule to carry out the following work:
Clean current contact tip and gas nozzle regularly, removing welding spatter and other impurities. Add Anti-Stick
agent on nozzles after cleaning to reduce undesirable spatter adhesion.
Check current contact tip regularly for wear or damage, replace in time.
Clean the welding unit by air-blasting from inside according to pollution level.
Attention:
This Welding unit has to be safety checked every year by JÄCKLE Company or another special qualified
electrician according to the harmonized standard
IEC 60974 – 4
