WIRE FEEDER

The wire feeder is mainly composed of driving motor, speed reducer, wire feeding 
roller, pressure roller, pressure adjusting component, wire feeding joint, support frame 
and other components. 

The welding wire enters the groove of the wire feeding roller by the wire feeding tube, 
and the pressing device applies appropriate pressure to the welding wire. At the same 
time, the driving motor drives the power to drive the wire feeding roller through the 
speed reducer, and feeds the welding wire into the welding torch for continuous
automatic welding.

Wire Feed Roller Specifications

Groove Type

Specification

V Groove 

0.6~0.8   0.8~1.0   1.0~1.2  (For 0.9 wires use 0.8 V Drive Roller)

U Groove 

0.8~1.0   1.0~1.2  (For 0.8 and 0.9 Fluxed cored wires use 0.8 U   

   Drive 

Roller)

NOTE:

1. V Type for Steel Wire                                  
2. U Type for Aluminium Wire and Gasless Wires 

Wire installation

Select the welding wire that matches the specification of the feed roller, pull the 

pressure adjustment handle down, the pressure roller component automatically 
releases, let the welding wire enter into the slot of the feed roller through the guide 
inlet, penetrates into the welding gun feed pipe, and then restore the pressure roller 
component to the original position, adjust the pressure handle knob to the optimal 
position, so that the feed roller consistently drives the wire forward. Only apply enough 
pressure to to avoid slippage. To much pressure can deform the welding wire causing 
feeding issues. 

Wire replacement

The procedure for replacing the welding wire is basically the same as wire installation, 

but at first turn off the power of the welding machine, pull the pressure adjustment 

handle down, take out the welding wire, select the required welding wire and the 
matched feed roller, let the welding wire pass through the inlet guide, make sure the 
welding wire is inside the feed roller slot and then penetrate the torch into the wire 
tube, push the pressure adjustment handle up. 
Since the feed roller groove will wear after using for a period of time and cause the 
welding wire to slip, so the pressure adjustment knob can be rotated down to 3~5

Note:

 The wear of the intermediate guide wire tube and the welding torch inlet can also 

cause the welding wire to slip, as a result the intermediate guide wire tube or the 
welding torch contact tip needs to be replaced when worn.
