Wire feed not working Miller 250 mig welder

Wire feed rheostat spins around and around does not stop.

Could there be a problem with the rheostat that causes the wire feed not to work.

Can I test voltage at rheostat? If so, what would I be looking for at each of the 3 leads coming out of the switch.

Also fan does not come on when main switch is turned on. Is this normal?

    Thanks for the help. I took the potentiometer apart and it was broken inside. I made a temporary repair and now the welder is feeding fine. I will order a new pot tomorrow.

Hi there,
If the knob spins all the way around (and especially of it didn't always do that), it's broken. This could mean that the nut that holds the rheostat in place has come loose, or it could be that the wiper inside the rheostat has broken off the shaft. To find the voltage measurements, correct schematics, etc, I'd need to know the serial number of your welder.

Regards,
Carl

Spoolmate 100 wont feed


Check for binding int he inner sleeve first, then increase tension as long as feed motor spins. If feed motor does not spin check wiring to make sure it is connected correctly.

I have a 250 bobcat that stick welds just fine but when you go to wire feed and plug in suitcase box wire feed unit wire feeds but it doesn't get hot enough to melt the wire. LF299725


What model of suitcase? Could be the contactor in the suitcase, could be the mig gun. Are you using the CV setting on the Bobcat, instead of CC? Is the Bobcat on the high CV setting and the dial most of the way?

MIG welder 250 feeding wire at erratic speeds


Gun trigger contacts or switch circuit is closing somewhere (shorting). Unplug connector and jump the two terminals if it works and will weld disconnect jumper if problem persists it is not in the gun or cable hose. Keep chasing it far as possible without taking bolts or screws out of machine unless you know what that stuff inside will do to you, pretty sure the problem is not in there anyway.

I have a IRON MAN 250 Mig Welder. that the wire don't feed, with regularty. I have a miller with the same tourch that dose the same thing. If you pull about 4 or 5 inches of wire out, with trigger...


Hi:

If you see rust on the wire then you should stop and change the gun's liner, change the contact tip and clean the feed rolls. Rust can accumulate inside the gun and make the wire feeding a problem.

Our MillerMatic 175 wire feed cannot be adjusted down enough. The rheostat seems to function, but even the lowest setting is now way too fast.


Your Millermatic 175 has syncronize wire speed-voltage feature in order to reduce the wire speed first reduce your heat (voltage). Try again.

If this was useful to you please vote. thanks.

Renegase 180


This fault is typical in most MIG/MAG Units. the feed roller/s need slackening off, pull the trigger so the rollers spin wire the wire not moving, turn the tensioning 1 turn check to see if the wire feeds, if not give a half turn on the tentioner repeat this half turn untill the wire feeds, bend the wire to the torch and pull the trigger, If the wire feeds then thats the correct setting. be awear of all safety rules. use gloves

I have a miller 180 autoset that does not feed the wire


If your welder is less than 3 years old your local Miller authorized service center will repair it for FREE. They can also check the serial number of your welder over the phone to see if it is still in warranty. For goodness sake DON'T tell them you've been mucking around inside the welder or they won't be able to help you.
That said, if the welder spins the feed wheels without any wire between them it probably isn't the board. There is the switch in the gun, the board, and the motor and brake assembly all needed to feed the wire.
