OPERATINGS

"ON" and "OFF" indicating switch on the FRONT panel.
Confirm the specification of the wire feed hose
Confirm the specification of nib base .It affects the extended length of the wire .
Confirm the specification of nib. It affects the electric resistance.
Confirm the wire slot of the roller is suitable for the diameter of the wire. Different di-
ameter of wire select different wire slot. Otherwise it affects the wire feed result.
Confirm the pressure of the roller to avoid slipping.
If the pressure is not enough ,the wire feed is slow speed.
If the pressure is too much ,the wire will be anamorphic.
The wire feeder can not work properly.
Confirm the flow of the gas and air proof.
We suggest the gas flow to be "L" more than 10D(D-diameter of wire ).If the selec-
tion is not proper,it also affects the welding quality.When using the CO2 gas,please
confirm if the heating power works properly or not .
Straight the hose of welding gun as much as possible .The bending radius can not be
less than 200mm.Otherwise it affects the wire feeder.
7.1 Gas inspection
Press the switch of the gun before the wire roller is firmed,preset the gas flow through
the meter to check if it is gas proof.Otherwise ,it affects the welding result.
7.2Rip into the wire
Select the specification of the wire ,materials according to the craft require-
ments.Firm the bolt and press the button on the front panel.The speed of ripping wire
can be controlled by the welding current knob.Unload the nib if necessary and load it
again after the wire is out.

13.1 Enlarge the length of the welding cable operation

The length of the welding cable includes the total length of the welding circuit includ-
ing the cables between the positive „+"of the power source. The cables longer, the
section area thinner, it caused large voltage reducing and large voltage loss, Moreover,
it affect the quality of the arc and the slag. So arrange the position of the welding ma-
chine properly to get the shortest cable.
The cable between the welding power and wire feeder is the shorter, the better Other-
wise it affects thd maximum speed of wire feeder are the maximum welding current.
on the condition of low speed (lower than 12m/min),we can enlarge the cable to 20m
when useφ0.8~1.0
Straight the enlarged cable, otherwise it affects the arc stability.
