SOURCE: lotos 520d plasma part not working, arc works great

Be sure you have the ground is connected to the postive terminal on the bottom of the front of the machine. Air pressure should be 70psi as the air flows out of the torch.

SOURCE: Just purchased this and need to know what the blue

If those are the power input, then the green is the grounding wire (safety ground).

If the unit is 220/240 volt, then the blue AND brown are the hot wires.
Neutral would not be used in this case.

If the unit is 120 volt, then the blue is the hot and the brown is the neutral, but your unit probably requires the 240 volt. Check the owners manual and label on the unit.

SOURCE: spectrum 2050 plasma cutter .

Check compressed air pressure is in limits otherwise unit will cut out. Try adjusting the pressure up. also make sure the supply pressure is correct as it may not be your plasma cutter at fault.

SOURCE: I just bought a Simadre520dx

They probably suspect board damage in the gas control / air control. They will analyze the pictures, looking or signs of failure. If found, they will either send you a new unit, or replacement boards to be installed. This is very common troubleshooting / diagnostic when the manufacturer gives its support staff the training and latitude to go this deep.

Give it more time, you are easily within the warranty period. Keep track of all communications though. Given that you just bought the machine, I am surprised that they were not more apt to replace it altogether unless another is not available.

SOURCE: I have a rstar ct-520 cutter/tig/arc welder. I am not getting any air through the cutting head on the plasma cutter. Does anyone have any idea of what it could be.

check first the pilot arc, if air pressure is there or not.next check solanoid valve working or not

I have a simadre cut50D an I don't have the ground cable can I still use it?


No. Check here for the specifics of how plasma cutters work: http://home.howstuffworks.com/plasma-cutter4.htm Without a ground cable, you cannot complete a circuit, and the physical basis of how a plasma cutter works doesn't function.

CUT50 plasma cutter no arc


Most likely HF spark adjustment needs to be done.

Green yellow would be earth ground. Confirm it with a test meter.

Solid green and solid brown would attach to the 240 hots- no return white.

Make sure you have a good ground. With high frequency you can get it to still arc but have a bad ground.

I'VE GOT HI FREQ BUT NO ARC. SMILEY TOOLS MTC 160. PLASMA, STICK AND DC TIG MACHINE. I DON'T HAVE A MANUAL OR ANY INFO. THANKS


Its probably the torch. Turn off the hf , with the machine triggered Measure the open circuit voltage from the positive o/p socket to the negative with a multimeter set on d.c . The correct no load output voltage for the machine will be shown on the spec plate as Uo = ........and whatever the voltage is. If you get the correct voltage try another torch or try stick welding.
