Sea water, or even salt dissolved in potable water does not burn your skin.I would not say it is that plain or simple, Salt (NaCl most common) is not an acid, it is typically pH neutral. Calcium chloride or magnesium chloride break apart to form more potent electrolytes than the commonly used...

Direct current electrode negative. Basically the mode you run on steel, stainless, titanium, etc.

Balance is not going to affect anything while in DCEN process.

Beautiful orbital welds on that piece.

Dude, two screws and the license plate would be out of the way... :pOh, and pics of the girl too.

Wrong section.

Latest job I am working on - just about done taking delivery of 14 tanks, varying from 3000 gallon to 13,500 gallon.taking the agitator motors and gearboxes off, cutting and removing the agitator shafts, and finally drilling a handful of new ports varying from 2" to 6" in the tanks for various...

Beads look nice man. I have to ask though - are the flanges machined after the weld process? Specifically are the bolt holes counter bored? It appears that a washer or flanged bolt head would not seat correctly due to the fillet weld dimension.

If stainless is not going to have a full penetration weld with a purge, then do not waste your "budget" on buying stainless in the first place. Use mild or aluminized steel. Paint it.Sugaring your stainless is removing the qualities that make stainless desirable in the first place.

Congrats! I did something almost similar in the middle of January - I gave them my two weeks. They did not try and keep me though, so I started working for myself and am now a contractor working under my own name as a sub for my old company's competitor :)Pay is waaay better as a contractor...

Doesn't he already have half a dozen welders at the house?

I typically hit the corners of the foot pads with a 4 lb drilling hammer while it is still warm to flatten it back out. I have tried different things like bolting the pad to a blank pad prior to welding to keep it flatter, but with a beefy fillet weld typical on many structural feet, there is...

You need to purge stainless with argon. So you can use the same bottle if you are welding with argon. As for the cost of cylinders, that is how the game is. I have 3 of the big 330 CF bottles in my garage for my TIG setup. Unless you plan to weld very infrequently, do not waste your time...

It is a Baldor 10 HP motor coupler to a 10:1 gear reducer, coupled to a Positive Displacement pump. This particular one is going to a juice plant. Suction on top, discharge on bottom, with 4" sanitary fittings. Used for moving orange, strawberry, etc, whatever is being processed at the time.

Some more work - not a lot of welding per se, but more of a lot measuring and accuracy. I bent the 1/2" tubing by hand and welded the tubing hangers.Swagelok anyone? :p

2% Thoriated, 2% Lanthanated, E3, I have used all of them on Miller inverters at work and at my place. They all work well. Some show the tips after so many arc strikes and that there is less spitting etc, less degradation, etc. Take it for what it is worth - I weld between 2 - 8 hrs a day on...

A little quiet, so here are some more sanitary welding pictures to motivate you to get on the torch...4" x 14 GA. 304L Miller maxstar 150, touch start, 3/32" 2% thoriated Outside is buffed, inside fully purged.

Host them somewhere reliable...

Cyberweld was the best pricing I could find.

Do you have the headlight upside down? Why is the cutoff on the opposite side? (Light should be on the bottom, shielded on top).

I would love to have one of those in my garage. I get back to shop work maybe twice a year, and the table is always covered with shit from other people. No one uses it except me.

Beats me...Here are some photos from a cart/cage for a diesel generator we have at the shop. Had shitty little 3" wheels that were only good for smooth concrete. No casters either on the factory setup.

Finishing off the Civic downpipe project...

@UrbanSmoker I started to brush it, but ended up pasting it with acid/pickeling gel and after letting it sit I hit with some scotchbright to clean up the heat stain.What filler are you using in those above pics for the butt weld? .035/.045? I need to pick some of that up. Plenty of times...

Anyone hungry for some pie?This is a current sidework project - 2000 Civic SI with an HX35. Owner wants to retain A/C compressor (Florida) so the downpipe is tight. A standard radius 2.5" 90 would not work, so I made a handful of 15 degree pie cuts and was able to squeeze it in there, as well...

As Iong as you use tubing and fittings rated for vacuum, you will not have any problems.

Right on man. You running a root pass without filler and then a cap?

If you look at them on McMaster Carr (tube fittings, push to connect) they will list which are rated for vacuum.I used them back on my eclipse for vac & boost without issue.

At work :p

Is that sch40 pipe for a coolant pipe? If so, I think sch10 would have been more than adequate ;)

Hell yeah man :)We have a swagelock rep that comes by frequent enough and we buy enough to get hook ups on pricing here and there.The top port is a 1.5" S-line fitting for the fill port, as well as doubling as a breather too.The cooler power supply port on the back of the 280DX is one of...

A few more now that I have to DIY cooler running and the bottle on.

Almost 1/2" filler rod huh? :aha:

Hobart's TIG welder is a fine machine to start with

It is quite the tag, but it is worth it if you are going to be making any money off of it. Besides the amperage range, and the ability for independent AC amperage upgrade, the AC freq has a much wider range for aluminum work. Other than that the features are identical from what I can tell off...

Not a replacement - just another model to bridge the gap between the 200 & 350. And you can buy the amplitude expansion for $500 if you need it. Basically a 350 as far as features go and adjustment range. I love it, had it since mid January and have about 15 hours on the arc timer.

New welding cart that is appropriate for the new welder. Stainless 2" sq tubing 7 ga. - I will make provisions to secure a 330 CF bottle on back, and a custom water cooler in the bottom under the machine

I got you - right on.Here is a 20 ft stainless ladder I built from 1.5" sch 40 that will go up against the side of a tank.

What's that big ole' black spot in the middle if the weld there from? :p TIG weld man, not stick weld ;)

I was referring to GTAW (TIG) processes.

I notice some have problems running out of argon, or lack of purging due to argon cost/limited supply.What size bottles are you guys running/maintaining? I have 3 330 CF bottles in my garage and never let 2 stay empty. I get a good price, about $30/bottle on swap from my local AirGas in Tampa.

What is your turbine housing parent material? Stainless?

Where are you getting your information? And what do you mean by oddball?316: Ultimate Tensile Strength, psi 89,900 Yield Strength, psi 60,200 Elongation 45%304: Ultimate Tensile Strength, psi 73,200 Yield Strength, psi 31,200 Elongation 70%What is your definition of weak and what are you...

Good fit ups and welds. Did you back purge the tubing at all?Did you weld the v band assemblies clamped together?You will not have any flow issues with a 4" muffler I am sure.

Neg on the water cooler, I am building a custom one with a Marathon Electric motor, Procon pump, and an 18" drop piece of 6" sanitary SS tubing with some bungs on it. The cost of an out of the box cooler is a little ridiculous in my opinion (yeah, I know I just spent almost 5k on a welder...

New welding machine arrived today. Need to pick up some mating NEMA L6-30 connectors, and probably some 10 ga. SJ or SO service cord to wire it up. My Everlast is setup with NEMA 6-20 and 12 ga. power to the wall - not enough for the Dynasty. Already downloaded the lastest firmware to an SD...

Not immediately, but for the semi frequent aluminum work 200 amps is not really enough head room for the duty cycle rating. And I really like the expandability of independent AC amperage adjustments found on the 350 DX available via upgrade. Obviously for home fabricators the 350 is pretty far...

Electro polished tubing?That has a pretty bright shine to it, moreso than the sanitary tubing I use daily.

Pulled the trigger and ordered myself a Miller Dynasty 280DX today... I am excited for it to come in. I have been using a maxstar 150 and an everlasting 200DX for the past couple years and ready to move up.Going to make a custom cart and water cooler for it once I have it. Already have an SSC...

I just had a 16 bottle rack swapped out at work today. 330 bottles too. I swapped out 2 of my personal 330s about 2 weeks ago with no issue at my local AirGas.
