Question about Miller Welding Tools

1 Answer

I have a Miller Shopmaster power source attached to a Miller model 22A wire welder. The problem is when the heat is set above 150 the wire feed pulsates and will not maintain a constant wire feed. Do you have any solutions?

Check to make sure wire feed brake is not set too tight and that all cables and gun are clean. Also check wire feed wheels are clean and in good shape

When I push the trigger I lose my voltage to run the feed motor, the motor works with other power source

Had the same problem with mine but mine isn't miller and don't know if your's is built the same but if you access the inside of the machine there's there's a large copper spool inside and that wire feed handle is powered through it. The connection heats up over time and becomes a short. I re spliced mine then soldered it and then cut piece of copper tubing and crimped it around the connection and soldered that as well.
Corrected the problem and I tried pretty much all listed solutions other then this first. Tried the new liner in the torch, the new tip and clamping the wire feed assembly with a clamp instead of the tensioner. All failed. I stumbled on to the fix accidentally when I was trying to install a more heavy duty fan. Hope this helps. Good luck.

How much does this welder cost?

That welder in new conditions should cost about 350.00 dollars. Used probably just 120.00.

Miller mig welder #175 stopped welding, fan comes on and wire does feed, just no weld.

This usually happens when the main Power semiconductors fail. You need to check out the two main places, the Power Supply, make sure ALL voltages are correct, and the main Output semiconductors, check these to make sure they are Not open circuit or short circuit.
Above is your support link.
You need to contact Miller and obtain a service manual, before attempting to service this unit.

It's called the fire feed wheel. They sometimes come in sets but, running .035, you probably have one grooved and one flat. Any welding supply that handles Miller welders should have them or be able to get them.

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.
