CD, if you have tinkered with oxyacetylene welding, TIG is very much the same, so, adhere to the basics you learned from torch welding, and you should be able to pick up TIG pretty easy.

Not entirely true that you can't re-temper aluminum. You post-heat it to bring it back to its normal condition after it has become work-hardened by a process known as 'annealing' Light your torch to a carbuerizing flame (sooty) and cover the workpiece until it's black with soot. Then set for a neutral flame, and heat the material until you see the carbon burn off. Then let it slowly cool on its own. At this point, it can be considered annealed, or 're-tempered' if you will.


When welding heavy aluminum, like, anything heavier than 1/4", pre-heat is a good idea, bring it up to around 350-400 degrees, and it will weld like magic. Also, pre-heat prevents the possibility of hot-short cracking, caused by the mass of cold aluminum quickly sucking the heat out of the weld and causing a crack, much like cast iron will do when you try to weld it. (Again, remember that aluminum has 3X the thermal conductivity of steel, which means the heat gets spread out quickly) Doubling back at the end of your weld eliminates a crater or fish-eye, which can also lead to cracking.

As for machine duty cycle, bear in mind this is at the full power setting. So, in other words, for a 200 amp machine rated at 20%, if you were running 100 amps, the duty cycle would be about 40%, meaning you can weld for 4 out of 10 minutes before you have to let the machine rest and cool down. If the machine has its own built in stabilizer, then disregard the information about de-rating the duty cycle, the factory number applies. But if you are adding on a high frequency unit that is seperate from the welder, then you do have to de-rate the duty cycle by 50%. But only if you are using continuous HF. If you are only using HF starting, such as on stainless or steel, etc, then, you don't have to worry about de-rating the duty cycle.

If you have to weld really dirty aluminum, TIG is the answer, because, unlike MIG, which continuously feeds wire to the puddle, with TIG you can hold arc and let it burn out the impurity before adding filler metal. Sometimes, though, you may have to 'oxygen clean' the material. Best way is to use a torch with a cutting tip, light a neutral flame, then move the flame across the area you want to clean, and hit the oxygen cutting lever. This will cause rapid oxidation of impurities, which you then clean of the surface with the wire brush. Be careful when doing this, if you get the material too hot and hit the cutting lever, you can melt it!

The guy on youtube with welding tips and tricks has some really good videos, and as much as it pains me to say it, he's a better welder than I am on a lot of his stuff. But remember, welds don't have to be pretty to be strong. I have seen many a TIG weld that looked nice and pretty and there was no visible lumpy weld, crack and break (not enough filler metal, trying to run the seam as neatly as possible). Contrarily, I have seen some chit that looked like wads of chewed bubble gum, hold together for a long time.

Just remember that aluminum is only 1/3 the strength of steel, so, when you do some bend tests, don't be discouraged when it breaks on a root bend. Or even a face bend. This is just the nature of aluminum. Annealing will help somewhat, but again, we are dealing with a material 1/3 the strength of steel, so, just bear that in mind when designing, fabricating and welding aluminum.

Man I feel like I am in shop class.....I sure wish I would have taken that elective many moons ago when I was in high school. I cant wait to see what projects you guys bring to the table next time. PSG-1 you thought about a new project? Are you still debating making your own line of boats?

Bigwave, you can probably guess, but shop class was my favorite class in high school!

I still want to get into building some boats. Over the last few years, I've had about 3 dozen inquiries, but so far, no takers. People tend to balk when they hear the price of $2000-$2500 to install a jet unit and engine. I guess they think I'm trying to gouge them.

Obviously, they haven't priced what it costs to procure, maintain, and operate all the equipment required to do it correctly. That's a big part of the cost. The other part of the cost is for the skill and experience of someone who has been there and done it, and knows what it requires for it to work, and work for a long time with no issues.

Had a local guy contact me the other day, he's one of my youtube subscribers, and lives about 40 miles from here. He has a hull and was interested in a build. I told him I still have the VX110 engine and pump that I was going to use for another build that the guy backed out on. Hoping maybe he will want me to build him a jetboat so I can recover my money for that engine, as well as making some more money.

But if all else fails, I think I'll be building a river class jetboat next spring. And it WILL have a UHMW bottom. First test for that boat, (after a maiden voyage/trial run here at home) will be to run the Pee Dee River from the NC/SC line up to Blewett Falls, going through all those lateral steps and rocks.

So, either way, I'll be posting another project soon!

man, and I thought this thread couldn't get any better.. well I was wrong. I eat, sleep, and breath this stuff. Country, what machine are you looking to get? I was looking at the miller Syncro wave 200 or 250 dx... But prices are STEAP!!!! lol. Probably end up with a everlast, but kinda hesitant as Ive never owned one. Hope I can start my build soon. post more pics up if you can, You have one sexy boat sir. PSG-1... nice posts. I sure do appreciate it when people take their time to share their experience and knowledge with others.

I think I'm going to get the Eastward TIG 200. There is a pic on page 62

Well I can hardly believe it but it’s been one year ago today I started this build thread,

I was thinking like 6 mounts to transform her and to my own defense I really didn’t know when I started this project that I would do all the mods that I’ve done. There was also a point when I said hey, WTF are you doing, this isn’t a race slow down enjoy the family, fishing and girlfriends a little, and so I did.

I can say for the most part this build is complete and it really is, I have a couple more hours to fab some panels, a few little detail things and that's it for me, then she goes out for the “Seadek” Here are a couple of pics of what she looked like when I got her, a couple mods along the way, and how she looks now.
I want to thank everyone for their support and encouragement, it’s been fun…………………………….. :mrgreen:

Jerry thank you so much,

I'm sure I've said it before but I believe its worth repeating. There are a few really cool, superior, extensive builds on this forum and yours is one of them, it really stuck out to me. It was the motivation for me to do a really cool build as well. Marry Christmas to you and your family as well.

Hey thanks brother and yes its hard to believe just how fast time goes by sometimes. The weather is going to be nice all weekend so I will finally get to finish the floor. It going to look pretty cool, pics forthcoming. I'm also going to look at Evinrude Ocean Pro 225 I ran across. The guy lives local and I think I can buy it right. If its as clean as he says it is I will try and make a deal. It would be perfect for the toon project...................................................... :mrgreen:

Sad to see you moving on Dave! Good thing is you are pretty much done and can use it for what you built it to do.
One of these days you will shed a single tear when Im posting fish pictures off my boat...lol
