My miller 175 wire feed does not feed wire at low number settings

Usually, the drive motor voltage is derived from the weld voltage, so if you lose, the weld voltage, the motor will not turn. Feed some wire out in a setting that works, then switch to one that doesn't feed, and see if the wire will arc. If you have a voltmeter, check for DC voltage at the polarity changover. Might be a bad voltage range switch.

Miller deltaweld 652. Turn main switch on and you here a humming sound and the main contactor does not pull in??

Sounds like low voltage to the contactor. Reasons could be wrong input jumper settings for input power. Weak input three phase power. Bad control transformer (supplies power to contactor coil through the power switch). Just need to "dig" with a voltmeter.

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?

Im working on a old Rheem pac unit with a faded model and serial number! When I arrived the condencer fan was running real slow and nothing else! One fuse was burned out in the pull box! The contactor was...

Fan motor is going out or the capacitor to the fan is bad I suggest replacement of both the fan motor and the capacitor which should always be done any time you replace the motor. Also check your wiring again you have a wire connected to the fan that is feeding voltege straight through to the motor. Your motor should have 1 black wire that goes to on side of the contactor 2nd wire should be white and it should go to the common side of the contactor (oppisite of the black) there should be 2 brown wires both of these should go to the capacitor. One of the brown wires may have a stripe on it if so it goes to the side of the capacitor that is marked if no stripe then it does't matter which side of the capacitor it connects to. Also check the contactor to see that the following hook up is proper. First the contactor has L-1 L-2 marking These are the voltage leads into the system from the power supply. Each side L-1 and L-2 should have 110 to 120 volts on each. Second on the top of the contactor there should be T-1 T-2 these are your terminal feeds the should feed the power to the unit and should have 110 to 120 volts respectivly. There should be 2 terminals at either side of the contactor that are your 24 volt feed from your transformer one connects to the left side of the contactor and one connects to the right side. This is the feed from the thermostat that signal the unit to come on. Good Luck on your repairs hope this helped you in some way

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.

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
