Snap-on YA219B wire feed issue

Hello, I am new to this forum and I am really hoping someone can help me. I bought my son who is relatively new to welding a Snap-on YA219B 110V MIG welder. For some reason the wire keeps bird nesting at the inlet guide. When I remove the bird nest, I can push the wire through the liner by hand and while the gas is off it seems to feed fine. It doesn't seem to bird nest when the gas is off. Once we turn the gas on it seems to bird nest. I have it set at 3/4 feed speed and the heat is set around 5. When I look at the chart on the machine the settings seem to be right for what we are doing and the wire size we are running. We have some welding projects to do but can't seem to get this to run smoothly with the gas on to barely get one spot weld done. Any ideas or suggestions. I don't think I have the wire to tight through the drive wheels as it isn't getting smashed or anything like that.

If anyone has experience with this machine or ideas I would be really appreciative.

Thanks in advance.

I don't have this machine and I've never run one. A quick web search tends to indicate they are temperamental in nature.

With the cover open to let you see the wire feed rollers. Everything set-up to weld

Power off:
Wire will feed freely by hand.

Power on:
If you pull the trigger but don't weld (Feed wire out into the shop 1-2-feet)
will the wire feed? Did you get the birds nest if so when?

Do you have enough tension on the spool so that it does not over run when the trigger is pulled or released: The spool should move at exactly the same time as the feed rollers.. there should be a slight tension on the wire between the spool and the feed rollers

If all that works then adjust the wire feed rate down by 25% < try to weld and see if the birds nest goes away.

Those are my generic basic t/shooting start points.

When did empirical knowledge get replaced by a theoretical education?

This is a month old so the OP figured it out or smashed the welder .

Rule of thumb!!

The drive tension should be set to slip (drive rolls spin) with a pinch of the wire between thumb and index finger .

Then how one holds the gun while welding plays in

Always in a straight as possible line which means sometimes much moving around of the welding machine

Another problem area is bending of the front of the gun where the cable enters the plastic .

If the tension is to tight it will cause a bird nest

This will also could cause the wire to burn back again causing a bird nest.

The bird nest most often are caused by the wire being stopped in front of the drive rolls with tension set to tight.
Some days it takes longer to pick which welder

then to do the welding
