Hi every one,

I have a miller 330 a/bp welder that ive had for about 10 years. Well yesterday I went out to strike an arc and I had no gas flow after the valve under the front cover.

Does anyone have a testing procedure for these valves? Are they 240v are they 12v I'm not sure where to start with this thing. I have gas to the valve.

Thanks for the guidance

If you can open it up there should be a label on the valve/coil that tells you the voltage. I’d recommend just powering it down (unplug it). And ohm out the coil. If a solenoid goes bad lots of times the coil is open.

Awesome thank you for that info.

Also check that the post flow timer is sending power to it.
In my case, it was a bad timer, solenoid was good.

Will do thank you.
