You've covered pretty much any pipe joint people would see in most production work. However, I havent seen any consumable inserts, like they use in powerplants and shipyards. If you gather any interest in doing a video for it, let me know what size pipe and I'll donate the rings for it.

As promised. .035 304 tubing to 304 compression fitting. Set machine to 100 amps and used foot pedal, never maxed out the pedal. I used .035 308l wire and purged the piece. 3/32 thoriated tungsten sharpened to a needle point. I ran 2 passes because I knew I was running cold since I was afraid the wr...

I picked up some .035 wire and tested amperage on the extra piece. I set my machine to 75 amps and hooked up the foot pedal. Im using a 3/32 2% thoriated tungsten. I put my ground on the fitting and lit up on that with really low amperage to preheat it a little before moving to the tubing. I put a s...

Thanks for the responses. I have the option to order some .035 wire, so I'll go that route. It will have a purge on it, and I'll preheat the fitting a little. I was provided a piece of scrap to get my heart right so that helps

Ive got some .035 wall 1/2" 304 tubing to weld to a substantially thicker 304 fitting. Its a socket weld, and I'm using TIG, I was just trying to figure out if I should match my filler wire to the tubing? Or is it manageable with 1/16th wire? I am on the verge of ordering some .045 wire since m...

I think I'm better off not being lazy and just going ahead and setting up a purge. Kind of thinking about buying a dual flowmeter.

I have a friend who wants a nipple welded in a stainless beer keg. I'm worried about sugaring the backside on something so thin. Is there a way to do it without a purge? I'm assuming I should pulse something that thin, any ideas of a starting point for amperage? I've asked him for a piece of the scr...

Hey thanks for the input fellas. Now I've got something to work with, just gotta get some more scrap and try it out.

Polished. Just like that, he uses it for cobia towers.
That is my 5th try, 140amps, 3/32 2%lanth tungsten 120hz, and about 35% cleaning. It just seems dirty, and cold. Whenever i get it to wet in it looks like one round bead instead of the way it looks on regular aluminum

Got some anodized aluminum tubing from a friend to try out. I've welded a little plain aluminum before, not much, but he said anodized is difficult to weld. Looking for some tips, or baseline settings to try out. Its 1" and 1 1/2" tubing, looks like about .125 wall thickness. Any recommend...

Thanks for the input folks. It is a fillet weld, nothing for code or anything... just practice in the garage. I had a guy I work with tell me not to point the heat straight at the pipe for fear of melt thru so I tried to lean the arc out some. I may be getting a little carried away with how much tor...

I have bee practicing welding some sockets in the garage and have started running into some issues. First, I'm running 3/32 thoriated tungsten, 1/16 70s-2 for the root and 3/32 after that. I am welding 1 1/4 sch 40 steel pipe fo a steel coupling. I found the pipe and fittings in a scrapyard down the...

I thought that was for converting a stick machine to scratch start tig. I saw a video that showed a dinse connector with an argon jumper. It seemed more like what I needed. Opinions?

I have a 160STH and I'm looking at replacing my power cord from the one that came with the machine. The power cord I am looking at is the WP-17 Superflex. My question is how does the gas line connect to this powercable? It looks like it has an opening down the middle for gas, but how do I connect it...

Thanks for all the input folks. I'm in the Hampton Roads area. I have a great group of guys working for me who understand that there are certain procedures/specs we have to meet wether they like it or not. I have also gotten to know enough about the project where I feel comfortable fighting for OT a...

So the story without too many specifics, is that I am a long term temporary supervisor of a pipefitting crew. When the opportunity came up I of course grabbed it up. Now after about 2 months I have come to the realization that I just do not like being a supervisor. I like doing the work, and even wi...

Thanks Gary for the encouraging words. I've been supervising for some weeks now to finish some work after retirements and things. I must say, it is a different challenge and the ability to basically temp run a crew for a long period of time is giving me the opportunity to decide if my tools are my c...

I'm currently running a crew of fitters now. I'll probably stay right there in the shipyard and see where it takes me to be honest. I'll make the decision to apply for a supervisory position or stay with my tools for awhile when the next ship comes in.

Like the title says. I just had my first completion meeting for my cap and gown, ring sizing, and alumni association membership for my apprenticeship. I walk across the stage in February for completing my pipefitting apprenticeship at Newport News Shipbuilding. Its been a long 4 years, I have met a ...

I have been using Tig for about 3 years, but only tack qualified, at work and I have found keeping weight and stress off of my torch hand and feed hand help the most. Also, asking my welders what they hate to see in tacks and how to fix it...

I got some 1-1/4 pipe at the scrapyard a while ago and built myself a storage rack for barbell plates. The pictures are for the second one I'm building for a friend. Its sch 80 steel pipe. I welded the joints at 85-90 amps with 70s-2 with and everlast 160sth. Comments, criticism are welcome.

Ah gotcha, thanks for the reply the potentiometer is 1k in the pedal I have. So its safe to assume it wont work.

I got a Varior OHASAA-1K foot pedal from a friend but it has a C810-1425(14 pin) plug on it. My machine (everlast 160sth) has a C840-725(7 pin) socket. I found a place where I can order the 7 pin plug, the question is can I just swap the plugs and use this pedal on my machine?

Thanks

Sweet, thanks guys. Now that I think about it, when I ran the first pass I was having to move slow to get the two plates to tie together before adding rod. On the second pass I wanted to be able to move slow and concentrate on keeping the weave tight and my filler addition. I have some that need the...

I made some T joints for practice out of some scrapyard steel. It's 1/4 thick if i remember right. I ran the first pass with no weave at 110-120 amps with 1/16 70s-2 then a weave pass at 125-130 amps with 3/32 70s-2. I am not a welder but a pipefitter with tack quals, and I have an Everlast 160sth a...
