You are going to be doing the same type of work I do at my shop. Because of that the 210 DX will be enough machine for your work. The lowest amp setting I have ever needed was 25 amps for some thin titanium. When going intercoolers Im not more than 175 amps. With the Dynasties the beauty is using th...

Arc Zone sells 4043 in .035 and .045

I would say you need to make a better ground point inside the pipe, or clean every contact point in the grounding circuit outside the welder. Wood has moisture and conduct electricity. with the high voltage of the HF start I could see it being an issue. Maybe look at at getting a wood surface that w...

To be honest The infinity sounds great on paper but in the end, out of my three helmets its the one I have used the least. The larger lens area really does not apply because the extra viewing are is out of my field of vision. It was a let down for me. Even getting the head gear comfortable took me s...

I have a Miller digital elite, Infinity and a 3M 9100 FX ADFLO with the 9100xxi lens. Love the 3M for comfort by far. I have been flashed a few times but it was my mistake. The miller X-Mode is rock solid and switching the lens every time you start an arc. The problem with the Infinity i find is the...

Have you contacted Tial about the warranty? They would also know the type of stainless used.

If it was me I would use it as a paper weight. The stress and heat cycling the turbine housing goes through would make any repair the weak point. Worst case you toast the turbo and the engine.

I would try it again with the same amps but increase your frequency to 150 and try and try to get a tighter arc length.

If you have access to a drill press you could use that to keep everything aliened. Make sure the deck and drill head are square. Clamp one end in the chuck and set the other against the deck. Move the head so the assembly is clamped between the chuck and the deck. Tack it, let it cool and weld it.

Also check the AC balance, too much cleaning action will case more than wanted heat in the tungsten.

I think there is only a few applications where a fully inert atmosphere is required for titanium welding. During my research I did come across aviation welding where it was done with a large trailing shield and a good back purge with a oxygen monitor. These parts were 100% quality control to the poi...

Did you make your pie-cuts or did you order them pre-cut? I know there's this one place (or several maybe) that sell them pre-cut. I need to get my hands on some more titanium this summer. I bought it from Ticon Industries. They seem to have the largest selection of titanium parts for the kind of w...

Yes I have my own performance shop. About 65% of my work is fabrication. I have a few customers that understand that it costs money to do things right and are willing to pay if the job requires it. This down pipe was more of a way of getting my name out there. Edit, The reason Im doing these types o...

Originally the plan was to have it done without heat tinting. Normally I do everything by the book as I can. Thank you Oscar for the info. The customer is fully aware that this my first part and knows it might not last as planned. If it does fail at some point the customer will get a new down pipe o...

My concern is that all of the contamination from heat tinting gets dissolved into puddle and surrounding HAZ. That's why it appears the tint "disappears" from the weld area. The contamination is going into the interstitial spaces of the crystal and the surface appears "clean". I...

zank wrote:Did you do all of the coloring after welding?

To start I did but I came to the conclusion that heating the pie cuts first was hindering my fit up so I had to redo one of the sections again.

Did you get a good purge? I'd like to know what gas lens you used? Has to be difficult, I assume you would weld and then let it cool, must have taken awhile When I did practice pieces without heat tinting them the purge was great. I have my purge bottle flow meter set so the ball is just floating. ...

After reading up on the fumes and gasses that are made and generated from welding, I got a little nervous. I read up on allowable exposure limits and went with a 3M PAPR with the flip up shield. I love it. Its comfortable and easy to get along with. I did try the under the helmet filters and did not...

Well after months of practice, swearing and maybe a few cries I have finished my first titanium part for a customer. I know my tie-ins need work, but they have come a long way. The piece is a 3" down pipe for a Nissan Skyline GTR. After welding this up I had to do some aluminum welding right af...

I use a 3 inch ceramic tile cutting diamond wheel. The edge is great for cutting and the flat surface is great for sharping. Once one side wears out you can flip it to get more life out of it. I used one for a year until I dropped my die grinder and bent the wheel. https://www.princessauto.com/en/de...

If you want it to look great, invest in some larger cups. A #12 does wonders for getting great colour out of stainless.

Foot control yes. 18g mild steel Mu suggestion would be to get some practice pieces and dial in youre set up. I would do that by just using the foot control. The pre flow when doing steel sometimes unnecessary but cant hurt, lust the amount of gas you will go through. Keep and eye on your tungsten ...

If it was me i would get a dual flow regulator. you will only need to use one bottle on the road or at home. I use HAVC tape that has higher temperature rating then the cheep stuff. I tape off my ends and punch a small hole in it to feed the hose into. I then tape the hose to the tape I used to cove...

Still working on being steady and consistent. De...

Pardon my ignorance, but why not use bent segments instead of pie pieces to make a bend? For me its used when you need a really tight bend to make something work. With titanium the mandrel bends are very expensive to buy. If you mess one up is a huge cost for mistakes. With the titanium pie cuts I ...

Thanks for the tips. The section you see welded above was my first try at it. As a less experienced welder, I have a tendency to over feed the wire fearing I'm going to burn through or lose control of the puddle. The rest of the header tube was welded with less wire and the beads looks less promine...
