bad air solenoid on plasma cutter troubleshooting

[B2Krawler]

I have a Mitec Cut 40, very similar to the Parker and other chinese ones, my air solenoid does not activate. if i stick a voltage meter to the wires going to the air solenoid and activate the trigger, the volt meter goes nuts, no matter what setting it is on, the solenoid says 220Volt on it, along with a bunch of chinese writing so that is what I set the meter to, but it goes nuts, bouncing all over the place,so im wondering is it the solenoid or the circuit board? Nothing appears cooked on the circuit board that controls air flow

I know i can send the unit back to parker for $300 and have them fix it, but that would be lame, i can find a new one for that nowdays

I have done several searches but have not found any sites that help you fix it yourself. do you know of any?

has anyone else had this problem, how did you fix it

Hello,

It is most likely the solenoid. Take a picture and let us see it.

I doubt its the solenoid. Mine died as well. It has to do with the control board. I am the Fab moderator on www.homemadeturbo.com and one of our sponsors sells the chinese ones and showed the fix.

It is easy to check the coil on the solenoid with power off just check if the coil is open. If it is good then it is the board most likely

stuck open + no sparky......I got a new one instead from longevity.com
