7. Welding
To obtain a high-quality weld, it is most important to select the right voltage step with optimum wire feed rate
and gas flow.
- Setting of cyclinder pressure reducer
Set the shielding gas flow rate at the pressure reducer on cylinder (6- 18 l/min). The gas flow rate depends
chiefly on the welding amperage.
- Loading of welding wire
Select the welding wire according to the material being welded. Mount the appropriate contact tip nozzle and
wire feed rollers. For more details see chapter 5 "wire feed".
- Select weld grade via weld-grade switch, coarse/ fine
Do not switch during welding operation
to avoid damage to the grade switches.
- Setting of wire feed rate
Wire feed rate is dependent upon voltage step, the material used, diameter of welding wire and type of shielding
gas.
- Start welding process by pressing torch trigger.
8. Service and Maintenance
Disconnect mains prior to any service and maintenance work!
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. In order to guarantee a
permanent good cooling effect pay attention to the cooling ribs of the water cooler: they should not be covered
by dust.
Attention:
This Welding unit has to be safety checked every year by Jäckle & Ess System GmbH or an special qualified
electrician according to the harmonized standard
IEC 60974 – 4
