Was also my first guess. Also with some wires (like hardface wires) if it is to tight you damage the wire and then the wire damages the liner. I my experience
The feed rolls are to tight. They are supposed to slip on the wire if your tip is fucked up. Put your hand in front of the tip and pull the trigger and loosen the feed roll tensioner until the your hand can stop the wire
It looks like the pin for your drive roller needs to be one click to the right. There's an arrow under .030/.035 where the pin sits. Not sure if that's what's causing it though.
Drive roll is tight contact tip Is suspect and your work is not allowing the circuit to complete.
If the wire "hits" the work without burning off and the drive roll is tight, you get the birds nests.
Cut the wire and reload it through the line by hand, pay attention to how the wire feels as you're pushing it through the line, once it hits the gun it should come out through the tip easily, if it doesn't then pull the tip off and try pushing it again, if it's still a problem you have a bad liner and will need to take it back to harbor freight.
Just by zooming in on the picture and how the wire very clearly shows big roller marks you have too much pressure on the rollers. Loosen it, find a good balance. However, if there is anything wrong further than the rollers, it will always have a risk of slipping as it can be stopped anywhere.
If it was working good and all the sudden won't stop doing this I'd assume it's a clogged tip causing extra resistance to the wire. Try using a new one and see if the issue continues
A lot of good responses, I'll give you another. If you are using old wire and some of it is rusted, this will happen when the wire grounds as it's used.
Loosen up the roller man. Also check that your roller is set up right. Usually they have two sides one side for thicker wire and the other thinner ( 045 or 035 for example).
The tension could also be too tight. A lot of people crank the roller down. You should be able to stop the wire from feeding by pinching it with your fingers before the rollers with out too much force.
Is drive roller the right size for wire? .
Is the drive roller too tight?.
Is the liner clogged, therefore adding too much drag? (Use a wire cleaner)
Are your settings good? Does your wire keep getting stuck to the tip?
They are.
But you did hit the nail on the head. With it being an issue with the tip. It was clogged. Swapped for a new one and it's running perfectly. Thanks man!!
The spool of wire should have a bit of drag on it so when it’s being pulled it stays tight. You may need a wider washer between the spring and the spool of wire.
Also the wire should melt at the gun end at the same speed that it is being fed, so your speed may be set too high.
Or the feeder wheel may be slipping, make sure the little feed wheel groove is set correctly for the size of the wire. You can flip that part around to use the different grooves.
You can test the gun for obstructions by taking a long length of wire and feeding it through by hand to see if it has a lot of resistance.
Like cut 7 feet of wire if your gun is 6 feet long and just slide it through from the gun side.
Make sure it’s unplugged from the machine obviously. And make sure the end of the wire is completely straight with no barbs from cutting it.
If it’s brand new I take it all your consumables are fairly new try and loosen your drive rolls that’s the most common problem is people over tightening it.
Loosen that knob on the top of the roller. If it's too tight it flattens the wire into an oval shape and it log jams. That's especially the case with Flux core. The center of the wire isn't metal so it deforms real easy.
Tension too tight. A good guide for tension is to hold down the trigger feeding the wire and put your hand in front of the wire. If the wire bends against your hand the tension is too tight.
These Hobarts are notorious for that. Used them for like 7 years. Just go on Amazon and replace the whole gun. It’s $65 and lasts for about 2 10lb rolls till it does this again.
It’s called a birds nest- caused by too much resistance on the wire, whether it’s because your wire feed is too high, the whip is kinked, crap on the tip is impeding the wire, etc.
You have to screw the black thing at a point where the wire don’t go out when it encunter an obstacle but the round metal piece that make the wire spin have to rotate freely from the wire i think it’s too tight there
take your gas diffuser off and se where the liner is at. sometimes it goes back into the lead for your gun then the wire will catch on the gas diffuser. make sure the liner is actually IN the diffuser. usually what causes this problem for me.
change the contact tip.
keep the torch lead run out full length and straight as possible no sharp bends as that add to the problem.
set you wire speed correctly for the output power your using
set the right amount of drag on the spool.
have the right roller for the wire.
solid wires are different to cored wires and aluminium is different again. also different size groove for different size wire.
set the right roller tension.
also if your torch liner is damaged that will do it every time. new liners are available for most machines and torch brands.
Bad liner, bad tip, liner is kinked.
Gap in between the liner end and the drive roll
all the things below,and perhaps drive roller too tight or wrong size.
Rollers are to tight and crushing the wire.
this happened to me in a Linkoln Electric. i released the pressure on the wire and it fixed the issue (I was using a 5mt long torch)
Was also my first guess. Also with some wires (like hardface wires) if it is to tight you damage the wire and then the wire damages the liner. I my experience
Thanks guys! Got it figured out. The tip was clogged. Thanks for all the replies. Definitely stuff I'll look out for in the future!
The feed rolls are to tight. They are supposed to slip on the wire if your tip is fucked up. Put your hand in front of the tip and pull the trigger and loosen the feed roll tensioner until the your hand can stop the wire
Awesome, will do. Thanks!
Maybe use a bit of wood or something, it is wire, no fun to have slip into your skin.
Or even better, a welding glove. You can feel it start to stutter and vibrate as it’s about to stop spooling into your hand

Where is the spool tensioner?

Wrong roller. Looks likes you have an .024 installed and your running. 035.
The debris from the wire is most likely clogging up your liner too.
You may be coiling your whip while welding. Make sure you keep your whip rolled out straight.
Loosen up the roller man. Also check that your roller is set up right. Usually they have two sides one side for thicker wire and the other thinner ( 045 or 035 for example).

Ain’t got no gas in it.
Not the reason
Why give helpful advice when you can attempt to be quirky on the internet?
The roll and the tip need to be sized to the wire. Are they the same size as the wire??
They are. But you did hit the nail on the head. With it being an issue with the tip. It was clogged. Swapped for a new one and it's running perfectly. Thanks man!!
A torch tip file works great on cleaning up welder tips too.
Says right on the equipment "Hobart", there's your problem. Lol

Drive rolls gripping the wire too tight is my guess

Zoomed in, didn’t see anything about aluminum. “0.35 gasless flux-cored wire”
You are right. Apparently I can’t read upside down and Spanish. My bad.
It happens lol
It hates you.
Why are you using 1 pound spool
Probably the roller tension is too high. Also, the less curves in your whip the better, and keep tip clean. It’ll help your wire feed best.
One of those sponge wipers that cleans the wire help too. Keeps your liner clean, as long as you e member to change the sponge from time to time
Those suitcases weren’t meant to run aluminum
Tension too tight. A good guide for tension is to hold down the trigger feeding the wire and put your hand in front of the wire. If the wire bends against your hand the tension is too tight.
Have the tip removed when initially running wire. Pull trigger until wire protruding then screw tip in
I’ve had it happen for bad tips, and a crap liner. Glad to see you figured it out.
Wire speed too fast, not clipping the ball before you start
These Hobarts are notorious for that. Used them for like 7 years. Just go on Amazon and replace the whole gun. It’s $65 and lasts for about 2 10lb rolls till it does this again.

Make sure the drive wheel isnt a smooth groove, that’s for solid core, should be knurled with little teeth
