SOURCE: need wiring schematic for miller 140 wire feed welder
No problem,email, write or phone for this information, Miller personel are very obliging as are most Welding manufacturers.
SOURCE: northern tool brand wire fed gasless welder feeds wire fan work no welding?
You need to have the ground attached to what you'll be welding on. Make sure there isn't anything on the end of your wire. Also, if your voltage is all the way down it won't do anything either. Oh, one more thing, make sure you have a contact tip on the end inside the cone. That will be the copper thing the wire goes through with a really small hole. I know some of this sounds pretty obvious but if I hadn't done these things at least once.....I wouldn't know what to look at either. I also don't know your experience level and want to cover all avenues. Hope you find it!
SOURCE: millermatic 200 won't weld
first check on the plate that tells imfo of unit ,there is what is called duty cycle.If the duty cycle says per say 30%,that means you can weld full power for 3 minuets before unit will shut down to cool.if it says 100% duty cycle there is no limit on weld time.this is the first thing to understand,if that is not the case check the main contactor where the power imput wires go,pull the gun trigger see if the contactor is pulling in , it should if not no welding amperage.
SOURCE: . Hello! I have a millermatic 251 and a 252,
Flux core wires will run on reverse polarity (gorund +), for solid core wires you need straight polarity (ground clamp at negative ). That will take care of the problem.
Clean and tighten connections both inside and outside unit.
Check and secure lead connections to remote control.
Be sure connection to work piece is clean and tight.
Remove excessive coils from weld cables.
If continues to be too high (hot) and can't control it, then you should send your machine to be checked that's probably a problem with the PC1 or PC2.
If this was useful to you please vote. Thank you and good luck.
