！ Attention:
◆ The wire speed generated by the feeder is relatively fast and safety
during the installation and adjustment process is of prime importance.
Never point the welding torch nozzle to a face or other body part. The
speed of the wire exiting the nozzle can cause a nasty jab.
Brief Procedure for the Welding Operation
1. Procedure for MIG Welding
1.1. Wear the necessary welding protection equipment such as helmet, mask,
earplugs, protective clothing, gloves, insulating safety shoes.
1.2. Confirm the electrical grid connected to the welding machine is consistent
with the correct power supply of the machine.
1.3. Confirm that the insulation layers on all the wires and cables of the
welding machine are intact and that the cable set is secure and correctly
connected to the machine.
1.4. Confirm the machine is freely vented and that the vents on the machine
are not obstructed and no objects are lying on the machine body.
1.5. Connect and tighten the earth cable to the negative pole. Clamp the other
end of the cable to the workpiece.
1.6. Connect and tighten the welding(polarity) cable of the wire feeder to the
positive pole.
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.
