 Wire reel retainer. Screw in to retain wire roll adaptor onto wire reel.

 

 

-

 Wire Feed Drive Assembly. To change roller size release retaining screw, remove roller and turn 

roller around and slide onto shaft making sure the right size groove is in line with wire and refit re-

taining screw. The MIG181 comes fitted with a dual roller 0.6mm and 0.8mm.

 

 

-

 Roller tensioner 

-

 This sets the pressure of rollers, the best way to adjust tension is to slacken off 

pressure so that MIG welding wire does not feed, slowly adjust pressure until wire feeds

 

 smoothly, you should be able to stop wire feeding by holding wire and it should slip on rollers.  

 

If you have too little pressure wire will slip when welding causing unwanted Burn back into tips or 

erratic weld beads size.

 

 

-

 When using gasless wire, move internal cable to negative connector –

 

This then makes the torch 

negative, you would then connect Workpiece earth lead to + positive connector on front of machine
