Wire Spool Adjustment

 

 

Fig 4 

 

1.  Wire reel retainer

 

 
This screws onto wire reel holder to secure wire reel roll 
 

2.  Wire reel tensioner nut

 

 
This adjusts the tension on wire feed reel which stops the reel from over running and causing 
wire to come of reel (birds nest) when torch switch is released. Some times known as reel 
brake. 
 
This is set in factory, if adjustment is required do not over tighten as this can cause stress to 
wire feed motor.

1.  Wire Feed Drive Assy 

 

Make sure rollers are correct size for wire diameter selected, to change rollers release 
retaining knurled head screw fit rollers onto shafts making sure the right size groove is in 
line with wire and refit retaining screws.
