I was wondering how you guys fix your broken power valves, I seen where someone worked or owned a machine shop and welded it up and milled it perfect again! I was wondering how someone like myself that works in a body shop with a Mig welder would fix it and what kind of metal is it?
 

it's aluminum. You don't want to weld it with a mig or aluminum spool gun... at least I wouldn't, wire feeders don't have good "hot start" capabilities. A TIG is perfect for welding it... but welding it also causes it to be softer than original and is more likely to pull through again easier than before. I will be fixing a spare set I bought and if somebody doesn't beat me to it i'll post pictures. Basically the way it's been done in the past (the way I plan on doing it) is take some stainless steel bolts (i'm just going to use some round stock and machine it down, round off the heads, cut the end of the powervalve off, drill and tap it according to the bolt you're using install bolt, re-drill the end for the cable and slot the end after. Pretty easy fix. I'll let you know how long mine takes again if nobody beats me to it.
 
i've fixed my valves before. as a matter of fact, daman here posted the pics for me. those were probably the pics of my valves you seen. if you do a search you could probably find the thread w/pics. I like the welding method. i thought of doing the stainless bolt thing too, but thought it was mork work than the welding method. I tig weld mine and then re-machine the end. never had a valve failure yet.

I did one of mine last year using this method....probably over 3000kms on it with no problems...sorry no pics
 
here's the power valve pics again.

Thank's I'm going to look into getting a Tig welder have no idea how much they cost,
Does anybody have pictures of fixing them without welding them ?
 
TIG Cost... pricey. Depends on what kind of welding you plan on doing, how heavy the materials are, and the features you want to make life easier for the type of welding you plan on doing. go to the two links below to get a comparison between the two most popular brands. You'll have to go through through all the selections on the page though... I didn't go that far for you lol.

www.lincolnelectric.com
 
i put a post on here a while back that I will fix valves for you t/y'ers and i think it was mrsled who yelled at me for doing that. i still fix 'em:)
you need some fixed? also, i would recommend lincoln electric welders over miller units. at work our miller tig welder went back to them 4 or 5 times....junk! our lincoln tig welder has never broke once. it will out weld and is easier to weld steel and aluminum on the lincoln than on the miller. just my .02.
 
I run a licoln 180C Mig with a spool gun for aluminum in my garage. It cost me $1300.00 CDN for everything. I would agree that if you are looking for a perfect aluminum weld every time, TIG is the way to go. But for the home handy man, the set up I have works great. There is a learning curve if you aren't a welder by trade, but I was doing my frist aluminum project after the first 4" spool of aluminum was burnt off with experiments.
 
I do collision repair and have been Mig welding for 20 years but never welded aluminum before and if the aluminum spool gun will do stuff like my power valves I will just get a Mig welder instead it would make more sense for me.
thanks
 
Depending on the mig power supply that you have, a spoolgun can be added simply if it has the provisions. Mig-ing with a spoolgun is not pretty by no means. TIG is much cleaner and neater - call it a surgical style of welding. For example my Millermatic 180 has a spoolgun provision, although I don't have the gun because I cant seem to find the extra dough to buy it, I also don't do production aluminum welding here at home either.
