Contact Miller Welding for complete troubleshooting. Good luck.
SOURCE: miller syncrowave 200 makes buzzing noise from spark gaps.
Odd noises other than the normal sound of the spark gap working are often the result of dust and junk inside the case of your welder. That it also bogs down when it gets warmed up (fan comes on), also points to a need for some "annual maintenance" stuff being done.
Completely isolate the machine from the building power supply, pul the plug, open the circuit breaker, do whatever it is that makes the machine have no connection to any power.
Take off the covers with a 10mm or 3/8 inch socket (can't remember which)
Use a shop vac to **** out all of the dust and debris out of the machine. Low pressure (40 psi) air can sometimes be helpful to dislodge caked on dirt. Avoid any metal tools near the capacitor bank inside the welder.
Wipe off the fan blades.
Clean the spark gap electrodes by inserting and removing a matchbook cover, a business card, or a piece of white cardboard several times. Inspect the electrodes and adjust them according to the manual that came with the welder.
Check all of the power wiring connections for tightness by gently tugging on them. Look for signs of overheating on the power connections and on the internal connections to the welding terminals. Check the range switch for heating too.
With the cover still off, reconnect the power and turn the welder on. Look for obviously vibrating laminations on the main input transformer. If you see one buzzing back and forth, or if you notice lots of wear and tear on the varnish coating of the laminations, shut everything down and repair the loose laminations with some anti-fungal high voltage varnish.
Turn the welder off, disconnect the power, and put it all back together. Then turn the power back on and weld something, if htere is still a buzzing noise you'll need a Miller tech to solve the problem, you likely have a bad input transfirmer.

the problem is your project is not grounded, attach the grounding cable from your welder to your project your welding.
SOURCE: Miller Big 40 will not weld and has no current at the A/C outlet
open inspection door,which also the fine tuner knob is ,there's a 2x4 size circut board that snaps out with little force to remove,this is the voltage regulator board,look for 4700 ohm resisitor burnt into,tv tech can fix or order new board at $227.00 what i paid.

Hi:
Your machine overloaded and the Fuse F1 must be open, just change it.
Here's the link to the owner's manual:

Check section 6-4 for more details.

Good Luck!
SOURCE: The wire feed on my welder will not work.
Maybe you can get lucky like I did . Some times the acr volt selector switch gets corrosion in it and wont let the circuit board know to send power to the wire feed motor. You can cycle this arc volt. switch in my case it is the a,b,c,d,e, switch back and fourth a few times and this will brake the corrosion and your wire might feed again as mine did . This corrosion build up happens from not using and or sollecting the switch much usually on a welder at hm that gets very little use. it is common good luck .
