A couple older rig welders I worked with told me it is better to convert an oxygen regulator over to fit on an argon bottle than use a flow meter. These guys did a lot of pipe work in plants and in the field. When asked if it wastes argon they said something like "yeah, a little bit, but the co...

SA-200 Faceplate.jpg I recently bought a Lincoln SA-200 welder, so I got more interested in this topic. My welder has the propane conversion and uses a Continental engine (with magneto). The generator is DC, so it provides a very smooth arc. No rectification or filtering required. The welder has 5 ...

Of course I do usually have a helper who can turn me up or down on the rheostat when I need them to while on the job, but for practice in my garage that's a no go.

Without reading your advice I ran out to the discount metal business down the road and picked up some stainless at about 3/8" thick and 1/4" and just sat there and welded. Took some trial and error but then I flipped my machine in to the 190-120 gear and tried sort of a "dab and step ...

Actually, no, I'm using my android phone, I don't own a pc or laptop anymore.

My valve isn't shutting off the flow all the way and allowing Argon to pass through the gas lense when I don't want it to. How do I fix this?

For some reason the pictures uploaded rotatated 90 degrees. These are all horizontal and I am right handed.

The cup walking on this one was just walking back over with out filler rod to fix what I messed up with trying to do it the first time with filler rod. I didn't know the right rod angle to hold and didn't have the tungsten the right length so it would dip too close to the puddle causing some spots n...

It's taking me a while to upload photos.

A lot of difference a little thicker metal mad and running the 1/16 wire. All I had was er70s-6 but was actually pretty easy to run the first pass on either side. After I did that I ran another then switched from the 3/32 tungsten with a #8 cup back to the 1/18 tungsten and #12 jumbo to try to walk ...

I was just sitting here watching some odd Jody's videos and it made me think again about the thickness so I went back out into the garage and checked it again. It ended up being 1/16" sheet, but I have some 1/8" is can play with tomorrow and post some photos of and see if I can get down to...

I was dicking around with it a lot today. Part of the problem could have something to do with using metal that is 3/32 thick trying to T joint it. I might need to get a hold of some thicker material to practice on.

I generally Weld pipe, down hill API1104 but I own a tig setup that I hook up to my old '82 sa200. It is a weldcraft 26 series torch. I run a #12 jumbo gas lense, a 1/8 red tungsten and usually the same size filler rod. I am having great difficulty trying to learn this on my own. I see all these pho...

I have an old Lincoln SA200 that has the threads to the exhaust manifold worn out. I tried to re-thread the manifold but it wouldn't hold the pipe without leaking water into the manifold when it rained. A friend told me he used stainless 312 stick and it worked on his. Not on mine. Followed it up wi...
