My miller 175 wire feed does not feed wire at low number settings


Usually, the drive motor voltage is derived from the weld voltage, so if you lose, the weld voltage, the motor will not turn. Feed some wire out in a setting that works, then switch to one that doesn't feed, and see if the wire will arc. If you have a voltmeter, check for DC voltage at the polarity changover. Might be a bad voltage range switch.

I have problem on elemax shw190 generator welding machine, the problem in not giving enough power for welding. Wishing for your help thanks


It will be either the Amp selector switch is starting to fail or the AVR. I would start by checking the switch is not showing signs of burning. (You can order a replacement here>> http://www.generatorguru.com/shw190/?sort=featured)

If you are not getting the correct voltage to the electricity plug sockets then it is most likely the AVR. This can also show up as a surge in voltage as well as low Voltage results.

Hope this helps! :)

Lincoln weld pak 100, no heat penatration on the D setting


I believe your voltage control rheostat (potentiometer) must be worn out. Check your owner's manual for the part number and request it, it's not expensive and it is an easy part to replace. If you are doing that would be a good idea to do the same for your speed control rheostat.
Or clean them if you can, take off all the carbon particles that it build up with the time.

1 Answer

No or little ac output


By ac you mean receptacles, not ac welding? 
If so what about welding output on AC (DC)?

If welding is OK then you may have breaker or fuse problem.
If welding output is also low or no output your problem is the generator.
You should check your gen rpm to be normal. If so you may have field problem: rectifier, AVR etc.
If you can measure the field DC voltage at rated rpm, if it is missing (very low) try to find any circuit broken.
If you do not succeed answer this instruction in order to give you more.

My sp100 works,but very poor almost no spark.


MAke sure you have a good grond and a good connection between the welder and the ground cable and the ground cable and the clamp, Check the wire feed speed. Try turning the wire feed speed down. Make sure you have it on the right heat setting.

Lincoln ranger 250 voltage problem


Hi,
Check the current control resistor with an ohm meter. The center terminal should have a smooth rise or fall of resistance when measured to one end or the other of the resistor. If the resistor and the wiring to it are OK, check the shunt in the output it'll be by the "electrode" terminal. If both are OK you probably have a bad control board.

Regards,
Carl
