I am posting this, because I know there is a more efficent and effective means of doing this than what I have been doing. Currently I have a seperate 250cf tank that I use for the sole purpose of purging. It is in no way connected to my little maxstar welder, so right before I begin to weld I use a valve to let the gas flow through the pipe. Shutting the valve on and off for each damn weld, gets very annoying and ends up being very wasteful. I have recognized that some people setup their purge through the welder itself so it comes on when the arc is initiated.

My other question, is what do you guys use to cap the ends of the pipe? I've used aluminum foil, but it tends to fall off, and leak. Is there something that is quick to put on, won't burn off and will stay on?

Thanks guys!

don't have any pics of my purge setup but i have it t'd off the valve with a quick disconnect so i can take it off when i'm not using it. i have a ball valve on the hose to shut it on and off and a needle valve to adjust the amount of flow.

ends of the pipe: use cap plugs. they slip right on and as long as your weld isn't too close they won't melt.

i'll try to get some pics tomorrow.

 

haven't tried it, but you could make a cap out of metal, using tubing 1 size larger, and welding a flat circle on one end. Then if your caping ferrous material, you can use a med-to-high powered magnet to keep the cap forced somewhat tight against the end.

Also could put a fitting on one cap that would allow you to quick connect a gas source.

Magnets + TIG Welding = Magnetic Arc Blow (No fun)

 

went to lincoln welding school in december and they have a VERY nice regulator you can buy that has one main dial on it for tank pressure and 2 seperate regulators attached to it one for purging and the other for your torch, its spendy if you didnt go to thier school, like 300 something i think but i got mine for 185 since i was in school when i bought it, its VERY nice tho, definelty worth every penny imo

Any more info on this setup? If it saves me money on gas, then it would worth the investment for me. Is it actually a lincoln electric regulator or something?

I'll probubly end up doing this actually (minus the magnets). being able to quickly setup the purge caps would be a huge benefit.

 

i dont have a camera to post pics up but try to picture this,
in the center 1 main circle dial with the tank pressure on it, then attached to it is something that distributes the gas im assuming and on each end of that a ball regulator, which you can adjust the gas flow out of the back purge side and the torch side, i believe they call it "motorsports regulator" i would call lincoln, its definetly worth every penny, use one tank of gas for purging and torch side so its super simple too, i recomend anyone who needs to back purge to get one(sorry i suck at explaining lol)

Maybe this

I have yet to rig me up something permanent, but I was really thinking about using part of an old nitrous kit I have laying around. Mount the full throttle switch to the pedal with a long flexible finger so it comes on the second the pedal is tapped. And use a left over purge solenoid to control the gas flow.
I would have next to no money in it except for a few fitting, anybody think it would not work? Not enough flow through the solenoid at low pressures?

yeah thats it right there, thanks for the link becuz im handicapped when it comes to explaining lol, mine just doesnt have the big black dials just the small ones on the front

You didn't need to take that class to buy that regulator at that price . I got one, works great. I just use foil too.

2 regs is the way to go...

heres some pics for someone thinking of doing this setup, its the best out there.




heres the welding pedastal, as u can see the purge line on the bottom, so u can just sit your piece on the top, it spins and tilts in all directions to..

 

How long was the school? How much and where did u go for it? Tia

 

its in cleveland ohio at thier actual factory, its a damn good school, the instructors are ******* cool as hell and it was cheap, i spent under $1000 for the school, hotel, food etc... i recomend this school to everyone, just go to thier website and find the school link and give Bill West a call, sign up for the Basic Motorsports class

EDIT: its only a week long also, definetly worth the trip
