1.7. Connect and tighten the wire feeder control cable to the aviation socket.
1.8. Connect the wire-feeder gas hose to the flowmeter. If the flowmeter has a
heating power cable, then connect it to the heating power supply socket
on the rear of the machine.
1.9. Connect the MIG torch to the Euro socket adaptor on the wire feeder and
tighten the connection nut.
1.10. Switch on the machine and ensure the indicator light is lit and the fan is
operational. Open the gas valve on the cylinder and regulate the gas flow
to the required flow rate.
1.11. Ensure that the locating hole on the wire spool corresponds with the
locating pin on the hub, install the wire spool on the hub shaft and lock the
spool with the hub nut.
1.12. Ensure that the groove position of the wire feeding roller and the diameter
of the nozzle are compatible with the wire diameter.
1.13. Release the wire feed pressure and direct the welding wire into the groove
of the wire feeding roller, through the wire guide tube into the wire guide
tube of the central socket.
1.14. Adjust the pressure to the point where wire does not slip or the wire is
deformed by a too high pressure.
1.15. Press the inching wire feed switch allowing the wire to be fed through the
torch until it protrudes the required length from the nozzle.
1.16. Set the required parameters for the job at hand. To start the welding
operation, press the torch trigger.
1.17. During the welding operation, the parameters can be modified to suit the
situation.
1.18. After welding operation is completed, switch off the power on the machine
and distribution box.
2. MMA Welding Operation Procedure
2.1. Wear the necessary welding protection equipment such as helmet, mask,
