4-3. Specifications and installation of wire feed roll
The pressure scale of wire feeding is on the pressure regulating handle and the welding wire of
different materials and diameters have different pressure relationships, as shown in Table and
figure.
The values in the table are provided for reference only, and the actual pressure regulating speci -
fications must be adjusted according to the cable length of welding torch, type of welding
torch, wire feeding condition and wire type.
The “type 1” of wire feed roll should use hard welding wire, such as solid carbon steel and stain -
less steel welding wire.
The “type 2” of wire feed roll should use soft welding wire, such as welding wire of aluminum and
its alloys and copper and its alloys.
The “type 3” of wire feed roll should use coated welding wire.
Use the pressure re gulating handle to adjust the pressure of wire feed rolls to evenly feed the
welding wire to the conduit and allow the welding wire to have some braking force when
coming out from the contact tube, so as to ensure the welding wire does not slid on the wire
feed rolls.
Atte ntion! If the pressure is too great, the welding wire will be flattened, the coating will be dam -
aged, the wire feed rolls will be quickly worn and the wire feeding resistance will increase.

4-4. Manual wire feeding and gas inspection
Press manual wire feeding button to start the wire feeder and only the motor of wire feeder will
feed the wire. The current adjusting knob can be used to adjust the wire feed speed. Release
the manual wire feeding button to stop feeding.
Press the gas inspection button to open the gas valve for 30 s without starting the wire feeder
and welding equipment. Press the button again to stop feeding gas.
