a few PU205 questions

[Dne007]

HI, dne' here!
I bought a pu205 a few weeks ago and finally getting it setup. Got my argon, tungsten, etc. I've found I'm not very good at any of it, but my main problem is when using the Tig, the argon never cuts off after tigging, and the compressed air for the plasma never stopps blasting compressed air unless I cut the machine off ,and start over again, then I can cut once, but then I can't cut again until I turn it off; then the compressed air still keeps blasting. I'm watching my large bottle of Argon dissappear rather alarmingly during the Tig!!. Me and the Tech guy are playing phone tag; he always calls when I'm in the middle of something. Anyway, I have questions, but can't ask until I get the machine funtioning.; )

Welcome, Dne'! I don't want to get in the way of the tech support guys on this forum, but a search on this site suggests it may be your gas solenoid not seating properly, or requiring a spring adjustment. Other people who've run into this have fixed it themselves- I read your other post and something tells me you won't be shy about pulling the cover off the machine.

Thank you DaveO! I'm going to take a look at that right noW! Just needed a little idea of what it may be! ; )

Probablya dumb question, is the post flow know turned fully to the left?

[everlastsupport]

There are more than one tech guys, you are welcome to call in and punch in ext 203 and get me on the line.

But It sounds like post flow is all the way on or a sticky solenoid.

What a nice guy Ray is! I found the points finally, but I don't think they were in the usual place. The gap was very wide, so I put them closer as directed, and LSS, got the machine going! OMG, I'm going to rip a lot of metal tomorrow! lol I'm not sure about the pedal for the mig, I may use the switch on the handle for a while.

Im wanting to tig a radio patch panel in my '59 Apache, and need that gauge metal to practice~ hm, not sure where to get a sheet of metal like that for practice purpose. Anyway, I'm excited!!!

What happened with the gas and air ?... we went from sticking solenoid to HF point gap all of a sudden.

[Dne007]

Well, before I even removed the cover, the gas would stay on(air or argon), So I did what a member said, I removed the cover, took the housing off of the solenoid and stretched the spring somewhat, then the argon/air shut off like it's supposed to, but then the Tig wouldn't ignite! and I took in consideration of the post control. By Ray's instructions, I found the points and found it to be very wide, and put the points closer together and worked the toggle switch(as per Rays instructions), then it began working correctly. I was hoping to play with it this morning, but I have to babysit for a couple days, so maybe Monday I can get back out and see how it works.

Sounds like you're back in business- good on ya for doing the fix! That is one show-quality truck.

What gauge metal are you looking for? I just got done fixing a clothes dryer, so I wonder if an old appliance cover might provide practice steel. Heavily painted, though, it would take some cup brushing.

I need to learn what gauge metal is? whatever the gauge of my dash metal is on my truck. I need to weld in a new radio patch panel. Somewhere along the line in the history of this truck, someone hacked the radio panel. I ordered a radio patch panel to weld in, but need to really practice alot before attempting to install it.
Most of this project is on www.67-72chevytrucks.com I'll be posting some questions on Tig soon, but I know practice is utmost important; just need to know settings of the machine, can I butt weld it, and what size filler wire (if necessary) and what size tungsten. etc. ; )

This is the panel I'll be repairing. I bought a patch panel that will displace this mess. Should prove interesting! I may mig if my talent doesn't prove good enough with the Tig, but I'd like to say I Tigged it in place!
