Please contact the manufacturer on this.

with the brand and model# , go to SEARS PARTS DIRECT. You should find what you need. Good Luck Friend.

There should be a connector on the front of the machine close to where the wire gun lead comes out. The connection is probably labeled "control" . These wires may be inside with the wire spool.

Elmer, If you remove the gun assembly from the machine, if the machine is now not feeding wire, the problem is most likely the gun trigger is faulty. The switch contacts heat up and start sticking over time. If able too disassemble and clean trigger contacts. Check the attached links,instruction and guides, Good luck "I hope this helped you out, if so let me know by pressing the helpful button.

probably over heated and blew the reset button 100 amp welders have a duty cycle ( time in actual welding use ) of less than 20% that means for welding for five minutes you have to let it cool down for 20 minutes the lower the amps the longer you can weld for beware tat the total amperage of the welder does not mean that you can weld for a long time at that amperage on the plate on the welder is the duty cycle and you have to be aware of it or the machine will shut down

Look again there needs to be one.

most 220v welders have a NEMA 10-50 plug or the NEMA 6-50 plug--the input /output ratings thru recepticle and thru plug are same-configuration of plug prongs are different( Grainger Catalogue shows simularities and differences) main difference is AC Horsepower Ratings are different, and that applies Only on equipment that uses 3 phase, not your welder.Use an Ohmmeter to touch unpowered wire connection under shroud at ground and plug prong, then red power connection to corresponding plug prong, and again to black connection and plug prong,mark them w/ felt pen w/ corresponding colors (Green, Black Red). Change out wire plug to fit into dryer or stove recepticle, or make an extention adapter plug witch fits stove recepticle and extends out thru floor to carport and goes to 10-50 recepticle-whereas ground green goes to W position (Center) Y is Black and goes to Y Black, X is Red and goes to X red and cap off the white neutral coming from plug -welders and hot water tanks do not return unused electrcity via the white neutral (return) wire--they use up what is available on demand in heating elements or in welders - the electromagnetic field.GET HELP DOING THIS, by someone who has knowledge, SKILLS and EXPERIECE. I have 1 welder fitted to go into dryer plug which has 14-30 recepticle, and i have 1 where i kill stove circuit at panel, unplug stove, plug in 14-50 plug which has a 10-50 recepticle on other end, plug in welder 10-50 -p, flip cicuit breaker switch to on-welder has full power range capacity. No oven in use while welder going--but probably wouldnt run it anyway if on different circuit.Any doubts whatsoever--anything not 100% clear--DO NOT DO THIS or any other Electrical Manipulations--have a licensed electrician stub in a secondary circuit breaker off your main if load is acceptible and have him wire in the recepticle which your plug will fit into---.

It may need oil if it is getting power and is trying to turn. It will need replacement if it burned out. If it burned out and has 2 winding sets (4 wires) you will not have control voltage.For electric motors I prefer synthetic 20W oil. Sometimes you need to spray the shaft ends with some solvent to loosen the gummed lube that is there first.
