My welder won't feed at slow speed.Works fine on higher speeds,but not slow.Was fine Saturday.It's a Hobart Handler 120.I'm trying to weld pipe for a fence,and all i get is balls,not beads,was told to slow the speed down,but I can't.

Try moving the tip closer to your work and try turning your wire speed down Most people want to crank up the wire speed when it spits and sputters Turn it down See if this helps
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.
make sure rollers are clean and slots not wore out check alignment do not over tighten wire feed so it smashes the wire flux wire is hard to get a good setting make sure if you can set it for gas welding it is not on this setting
If you are using flux wire and not shielding gas, your clamp should be positive and the wire should be negative. Heat is provided by the electrical arc that happens between the wire and the material. Your welder by itself does not pre heat the material and with 3/16 material you should not need to preheat anyway.
The electrical arc is kept consistent by adjusting the wire feed rate and the current applied. You will need to experiment with these settings to find what works best with your welder. For this welder and 3/16 material, I would suggest you start at the upper end of the current scale and about a third of the way up on wire speed. The welder might have a chart for these settings in the manual or inside cover.
If the wire feeds too fast, it will push the probe around and you will feel pressure as the wire feeds out. If the speed is too slow you will get large spatters and intermittent arcs. When properly adjusted the arc will sound even and consistent. The arc gap should always be about 1/8 of an inch.
To maintain enough heat for good penatration, do not move the probe too fast, work in a pattern and watch the weld pool (melted metal) and not the arc. Watching the weld pool will clue you in if you are moving too fast or too slow.
Some welders control wire speed with the amps control, some control amps with the wire speed control. You might try turning things up until it runs smoothly without pushing back. If you're new at welding, it does take some practice until it feels right.
