bad ground connect , either on the job, at the cable ends or in the machine

May need to take gun apart and see if trigger is sticking or replace lead. we use Miller at work. The feeder has a switch that makes the trigger turn off and on with quick pull of trigger so you don't have to hold it entire time. check wiring to make sure it's wired right so your not bypassing the trigger switch. hope it helps.

What is the duty cycle of the welder?

Those parts have long been discontinued. www.usaweld.com has a conversion kit that will convert the original Piecemaker 14A gun to the current hobart H10 parts.

Bob, Those parts have long been discontinued. www.usaweld.com might have an adapter kit if you have a piecemaker 14A gun, or they have a complete replacement welding gun.

Check the Switch on the handle. Many times the two wires from the trigger down to the Mig Unit break or get a bad connection

Look under welder dealers in your town. Most will be able to sell you parts or order what you need.

Check to see if the wire feed pressure is set correctly. Sounds like it's a little loose.

Not a question.

Do an internet search.

First, UNPLUG the Welder! There is a small control board (2"x2") that the feed motor plugs into, it has a fuse on it. Here is what you do: Follow the circuit board trace that goes from one side of the fuse though a resistor then to the connector full of wires on the edge of the board, check that resistor for continuity it should read some value besides open. If it is open, this is your problem (as the drive motor ages it draws slightly more current than new, which should blow fuse, but instead blows the resistor). The resistor should be replaced with same resistance value, if problem persists replace again but instead of 1/4amp bump up to a 3/4amp for $1 or replace that drive motor for $150, you choose. Good Luck!

NOTE: As with any circuit board, take precautions to prevent ESD damage to board.

turn the wire speed down

I was a service tech/manager for 10 years and had my repair business for another 8 years after I left the company I worked for. Can't really remember that exact machine's theory of operation, but check your weld output contactor. Sounds like it might possibly be stuck In the closed position.

i took an old trickle battery charger,6 volts and energize the armmiture,all so called polarizing,google it ,shows how also

Take the spool off of the machine and see if the feed wheels turn. If they do, you probably have the wire stuck in the tip or the line leading to it -- replace as necessary. If they don't turn, there is something jammed at the feed rollers or the motor that turns them. My bet would be that there is something stuck in the lead to the gun or the tip. The whine noise is probably the rollers slipping on the wire. Since the wirewill not feed, the spool doesn't turn.
