My welder will only weld wide open.

I have the same welder. Worked well for 15 years until the drive bearing stopped spinning. I cleaned and oiled the bearing and it has been working like a coon on the farm since. Nice 120 volt welder....

Try replacing the circuit breaker. They can/do get weak and tend to trip before they actually reach the rated limit.

There can be a switch that makes the wire electrically "dead" so it can be fed through the liner. Also suitcase style welders have a sensor wire with a clamp that must be connected for the arc to be able to be struck.

SOURCE: I have a hobart handler 120/90amp wire feed welder

I have welded countless hours with Linde & Lincoln & even a few Hobarts & the only time that I ever had the same problem was when the ground connection either to the object I was welding, or the welding cable ground wasn't good & clean & tight. Same on stick welders also. I did develop the habit of grinding not only where I was preparing to weld, but where I was placing my ground clamp & that always provided a better "frying bacon" sound as I went along the business of pushing a bead. In a welder, the only other thing than that is involved is the step-up transformer and your wire. Hope this helps.

try changing the tip and make sure your ground connection is good on the steel and in the machine sometimes the ground wire in the machine comes loose
