Millermatic 211 temp light flashes when machine is turned on. fan is running and air flow is not blocked. if i unplug the little plug for the gun and plug it back in the wire will start feeding all by itself. i checked the wiring on the trigger of the gun all seems ok.

This machine is an auto adjust for different voltages.

The front end of the circuity is a PMPS or pulse mode power supply. No matter the input, the output is the same.
Most all small appliances today are built around this technology. I bet a small IC on the circuit board has gone bad. A good electronics repair man could fix this or you can get the board from Miller.

Here is a forum that may answer your questions.

This has been a problems that is really easy to fix as long as your a bit careful. The problems is the design of the heat sink on the processor, the design flaw makes it possible for dust to collect on the heat sink on the processor allowing the heat to build up very quickly when using the processor a lot which tells the fan to speed up to attempt to cool things off but because of the excess dust it cannot do so.
On the e-machine it is easiest to use compressed air to clear the dust on the heat sink for the processor, however do not have the computer turned on when doing the cleaning, and if your using a air compressor blow gun, you should limit the pressure to 100 lbs or a little less and then be careful not to blow directly on the fan so the fan spins up (by the air flow) too fast because it can damage the fans bearings.
Note: this machine will collect a lot of dust in the heat sink so when blowing it clear it will produce a dust cloud, you may wish to do it in an area where dust will not be a problem for other things, people, or pets.

CHECK COOLANT LEVEL.IF COOLING FAN TURNING ON COOLANT TEMPERATURE SENSOR WORKING.BECAUSE IT CONTROLS AND TURN ON COOLANT FAN AT A SET TEMPERATURE.SOUND LIKE ENGINE RUNNING TOO HOT. HAVE RADIATOR FLUSHED.REPLACE THERMOSTAT. HAVE ENGINE BLOCK FLUSHED.REPLACE RADIATOR PRESSURE CAP ALSO.SEE WHAT HAPPENS.

I always tell my customers that the best machine for a body shop is a millermatic 212 if you have 220V available if not, go to a Millermatic 211 this is one is a dual voltage unit 110V/220V. if you can afford it buy a spool gun SG100 for all aluminum parts, the machine will cost you 999.00 and the spool gun 215.00. Best investment ever for your shop.

Hi!!

Check

Temp. control knobs,

Most likely, the evaporator coil is covered w/ice, obstructin the air flow thru it and to the fridge side of the unit.

Remove freezer back panel (where the little fan is) and check for iced evaporator coil, if so, unplug unit and use a heat gun or hair dryer to melt ice, make sure all ice is melted andthe air duct going to the fridge is clear.

Once this is done, restart unit and set temp. 1/3 of the dial, ie. if the dial goes from 0-9, set it on 3. wait 24 hrs to make adjustments

Keep me posted!! Rate this post!!!

Don't forget to rate this post!! Good Luck!!!

have you checked that the rad is clear and air can flow through it freely,,,is it blocked up so the water cant flow through it freely ,is the fan realy working or sezed up so it cant turn round??
if all this is ok, they changing the temp censor or for a test run,,,short the fan temp censor plug out with a bit of whire this should start the fan up,,,(watch your fingers when doint this) go for a run to see if the motor stayes cool
