R-Tech I-MIG160 MIG Operation Instructions Manual - Wire Spool Fitment

Wire Spool Fitment

1. Wire reel retainer  Push and twist in, to retain wire roll adaptor onto wire reel   

2. Roller tensioner  Do not over tighten wire feed pressure roller as this can cause 

premature motor and roller failure.  Correct way to adjust tensioner 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 

Burnback into tips   

3. Wire Feed Drive Assembly  Make sure rollers are correct size for wire diameter selected, 

to change roller size release retaining screw, remove roller turn roller around and slide 

onto shaft making sure the right size groove is in line with wire and refit retaining screw.  

The INV160 comes fitted with a dual roller 0.6mm and 0.8mm  

4. Wire reel adaptor  Remove the wire reel retainer and wire reel adaptor, slide on roll of 

wire and refit the reel adaptor.
