SOURCE: Miller S-54D 115V digital wire feeder that does not weld right.

Hi Kevin,
Causes of poor penetration: Travel speed too fast, welding current too low,
poor joint design / and or preparation, electrode diameter too large,
wrong type of electrode, excessively long arc length.
Solutions: Decrease travel speed, increase welding current, increase root
opening or decrease rootface, use smaller electrode, use electrode with deeper
penetration characteristics, reduce arc length.

SOURCE: miller big 30 d wont weld

Probably your machines overloaded. Check your fuses F1 and F2 and if they are open replace them.
Both fuses are located at left hand side of machine, open it and you will find them on the bracket.
Check your owner's manual for more info about fuse replacement.

Miller trailblazer 275 stalls after about two hours of welding.....


there is a voltage regulator directly above the electric fuel pump on this welder, make sure the three connectors are making good contact, there are three wires attached to it, the center conductor is either violet or blue, if the spade terminals are not making proper contact your machine will shut down as you state
you may also have a "sticking" or faulty fuel stop solenoid
if after you remove and check the connectors at the voltage regulator, the problem persists, locate the local Kohler dealer, your engine has a 3 year warranty for parts and labor

Miller welder 330a/bp it will not weld in D/C straight or reverse no ark but will work in A/C its like there is very low volts I was welding and then could not strike a ark


It's likely that your pedal is the problem. Pull the cover and check it electrically - these have been problematic in the past. You can further troubleshoot by selecting constant output and test the output.

Have a Miller big 40 welder and the engine won't turn over


I'm not familiar with this particular unit--do you mean to say that the cooling system froze during the winter? If so, and the engine has overhead valves, the cylinder head, block, or both may have cracked causing water to leak into the cylinders which would have rusted the rings and cylinder walls (together). You are looking at major overhaul or even engine replacement (not what you were hoping). Good luck!

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.

Regards,
Carl
