Was welding with it. was welding fine . all of a sudden it quit feeding the wire. moved the handel around would still not feed it trigger 2 or 3 times and let off all of a sudden it started feeding on its own. finger was not on trigger. start and stop start and stop. turn power switch off to get to stop. took handel apart found 2 wires off and arking together. repaired the wires would not do nothing . took side panel off blown fuse. replace fuse still nothing power light is on. what could be problem . motor does not even move.

have you tried adjusting the tension on the flux wire? before you start feeding the wire into it make sure there isnt any kinks in the wire. seems like it doesnt take much for it to bind up once you get start welding with it im sure you will run into this problem quite allot. usually its from welding the wire to the tip. i have to be honest it can ve a pain in the ***
Usually a flux core only welds steel. It is a higher penetration weld than a MIG. Usually it acts similar to 6011 rods in SMA (Shielded Metal Arc) welding -- a.k.a. stick welding -- if you're familiar with that. I don't believe there is such a thing as flux wire for aluminum. There may be stainless wire for it, but I've never seen it. It probably could also be used for building up cast iron and cast steel, but nothing structural. I have a Chicago Electric one and I love it -- simple and it penetrates hard. My 90 amp will weld to 3/8" without breaking a sweat and if I baby it will go to 1/2" or better. It is difficult to go much lower than 12 or 14 gauge though due to the high penetration.
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.
