Question about Hobart Welding Tools
Try increasing the feed rate. Decrease voltage also. If still no luck, try checking the wire diameter. If you are using flux core wire, make sure the wire isn't too old and it hasn't been exposed to moisture. If you are using gas, make sure that the gas regulator is working properly. If so, then try getting closer to your work with the nozzle. Distance from your workpiece and wind can interrupt the gas shield, causing the wire to burn unshielded.

A schematic would certainly help, give Hobart a call and ask for a wiring diagram. or manual. Hobart are very helpful and may even give you guidance, you may have to pay the postage, they usually fax these documents so it will not cost you anything.

Get a volt meter, go to ohms setting , check transformer to ground for low to zero ohms reading. also look closely at transformer windings for foreign objects in between them, never know what you my find. If transformer is shorted to ground probably time to say some nice words over it before burial. Also just for kicks try a new gun on it, (there is a reason i'm asking you to do(this) see if you can find someone that has spare. A good honest repair shop would probably be reasonable if all else fails. to a least let you know if the transformers a problem. good luck

also do you hear any clicking when you depress the trigger?
You should. If nottry to jump the trigger wires inside themachine right where it goes out to the "gun"wires? worksnow? problemis in the gun cord somewhere.
Still not working? CHeck the contactor. SOmetimes a boxelder bug will get inthem and prevent them from working, or the contacts fry themselves.

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.
