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.
