William:



You can gas weld it.  Or, if you don't already have a

wire-feed welder and have an extra $300, get one from

Lowes or Home depot.  With a little practice you can

wire-feed weld like a pro.  Just use the flux-core

wire and don't worry about using gas (argon). Don't

buy a stick welder for what we do on airplanes. 



If you want to gas-weld it, just keep the heat

concentrated on the thicker part and make sure you get

penetration on both parts.  Cool the puddle with the

filler rod as you go and don't work in one place too

long.  Do a short tack on one side, then the other,

then 90 deg. from there and spread the welds around. 

Yesterday I was welding one of two tricky parts of my

throttle linkage (gas welding) and I finished one weld

perfectly.  The second one I got impatient and kept

going in one spot and melted the part off.  It's a

good thing my little helper wasn't around when the red

hot part fell to the floor or she would have learned a

new word.  



Good luck,



Scott Laughlin

Thanks Scott, I've been fighting the temptation to buy

the Lincoln Electric Weldpack 100 HD for $350, it seem

that it will do the job. My problem is that this might

be the only arc welding Ill be doing in this project,

after this it will be sitting in my shop collecting

dust. So far Ive contacted one professional welder

and he is asking $120 if I go to his shop and $180 if

he do it in my home. I have a friend who can stick

weld it but he has been unavailable lately.

I've got the same dilemma.  I've got an oxy-acetylene welder that I've had for years, but even trying to use it on 6061 has resulted in nothing more aluminum slag.  Now I have reason to do some welding on my plane - specifically the overflow tube on my right wing broke off while I was transporting it to the hangar, and I am more inclined to buy a TIG welder that I can use for other things than to pay $100 (or more) to have a welder come out to my shop for a one-time fix. 



Does anybody have a good suggestion for a small TIG welder that runs on 120V and doesn't cost an arm and a leg?

I don't know if there is such a thing as a small inexpensive TIG welder. 

Last time I was tempted, a Lincoln 175 was about $1300.

Bill,

I welded my first aircraft fuel tanks with oxyacetylene and it was much 

like riding a unicycle in a dark room.

Joint design and material selection are the critical issues with gas, 

but it can be done.  You need to work in

3000 or 5052 series aluminum to get good results with gas. Do lap joints 

to get better at it.  Edge welds are easy

but notoriously weak in gas welding.

The cheapest thing I've seen is a TIG and ARC welding solid state 

inverter technology unit from Harbor Freight

for $250.  Not sure how durable or repairable it would be, but it might 

work for you.

See link.

I use a Miller Syncrowave that does TIG nicely but it was expensive at 

$1500 or so.

I second the Lincoln 175.  I got one at SnF  several years ago and took 

the ACS welding course.  It's expensive compared to a cheap stick welder 

but wonderfully versatile and effective.  I had tried gas welding 

aluminum, using a Henrob torch, and cheap aluminum solder with no 

success but the Lincoln made every welding job possible.  It still takes 

a lot of practive but you will be amazed at the times you use it that 

you wouldn't have thought about welding before you got it.   Bite the 

bullet!

These guys:  http://www.htpweld.com/  have some really nice machines and

I see they've introduced a new small tig. I've got their 201 Invertig

and like it a lot. No affiliation, blah, blah.

All-

    Did I happen to mention that, last I knew, even the "Cheap Stick Welder" 

from Lincoln was MADE IN THE STATES? If they've outsourced since the last 

time I checked- don't tell me. It's nice to be able to point to at least one 

superior product that was competitively priced  with a sticker that said 

"Made in the USA".

    Don't get me wrong- if it weren't for Harbor Freight, we'd all have more 

money in our tools than in our projects. Lincoln was the notable exception.

    Talk about irony.I was once talking computers with a member of a heavy 

equipment trade delegation from Belarus (Old "White" Russia). We got on the 

subject of how cheap RAM had become, and I noted that most of it was now 

made in Taiwan. He snorted and said "That's the good stuff- now everything 

comes from Indonesia".

    What can you say. MiG outsourced to China years ago...........

                                                                             

                                            Bill

                                                                        do

I have found the people in my EAA chapter to be a real help on things 

like this.  If you have a chapter nearby, then you will likely find a 

good welder among the members who be very happy to help you with a 

welding task.

So, if you are not already a member of your local EAA chapter then 

join it.  You will find lots of resources there.

A friend of mine, a Pitts builder, got a Lincon Sq Wave 175 on Ebay and there were two listed then    But none now    I bought a 175 new years ago and it does well in the hands of a hack     Check Ebay    Murray
