A Little 350DX Project

admin

Got another little project where I was able to utilize the VP function of my 350. These are a couple of longer tubes that go to a helo jack stand I did earlier this year. They use this particular stand for a few different birds and each arm has to be a different length.Anywho, material is 6061. The tube is 3/8" where it gets welded and the cap is 1/2" except for the center web. I used a heat gun to pre-heat the parts for about 10 minutes before welding. Only cleaning was a wipe down with denatured alcohol.I used a 1/8" tungsten sharpened to a point with a flat ground on the end. I set the machine to independent polarity and used a 100%/70% ratio of EN/EP. Total amperage was 260 wich equated to 281 amps EN to 196 amps EP. You can see the result of this in the last pic. This is a shot of the tungsten after welding both parts. as you can see, it has very little wear after welding at such a high amperage. The other settings were as follows:Tig start amps = 60 amps @ 60 ms.Gas flow = 18 CFHStraight Argon gas1/16" 5356 fillerHz = 120Balance = 75 Attached ImagesProud to be self-employed and not have to rely on ANYONE but me to make my way in this world.Dynasty 350DXDynasty 200DX MM 350PMM 210MM Passport PlusSpectrum 375 Extreme08' Trailblazer 302
Reply:I'm new to TIG welding, but that strikes me as a lot of stickout. Is it the gas lens that allows you to run like that? (or was it extended just for the pics?)If it is the gas lens doing it's thing, are you close to the maximum you could "push it" to with 18CFH Argon flow?

Reply:From what I can see of the welds they look great! And the bike looks like a factory made one, great job on it as well.Miller Thunderbolt 225Millermatic 130 XPLincoln HD 100 Forney C-5bt Arc welderPlasma Cutter Gianteach Cut40ACent Machinery Bandsaw Cent Machinery 16Speed Drill PressChicago Electric 130amp tig/90 ArcHobart 190 Mig spoolgun ready
Reply:Great post and info Mud Spaz. Thanks!! BTW, I am cooking tungsten like mad on my latest project, and I am running a 1/8" tung. red. Sharpened basically the same way. Which type of tungsten is that one you showed?? Thanks in advance, Paul.And then, after so much work...... you have it in your hand, and you look over to your side...... and the runner has run off. Leaving you holding the prize, wondering when the runner will return.
