can it weld a 3/4 steel pipe?

It depends on the thickness of the steel and if it is galvanized or not. I was able to weld 1/4" angle but had to turn wire speed up and make big puddle weld to secure the members together. I'm sure it will work as long as the member is not under stress or heavy forces (weld will break).

Yes, it can for a flux welder I'm very impressed. I've welded car panels two steel rods together and a broken sway bar. Just do the necessary prep work. and no galvanized steel the fumes are dangerous.

No. It's designed for styrene plastic welding. You could maybe get the pieces to stick together for a short time, but there would be no strength at all.

I have not welded exhast pipes, but I welded other material about the same thickness and it works quite well. You just have to select the proper settings.

Yes you can add 3/4 pipe extensions. My neighbor added 5 3/4" black pipe extensions to dig a shallow well.

hi you would have to cut off the wedge that's already part of the machine and then weld your 4way on .I think you'd have problems with not enough power.Its a good idea but If I was going to do it I would get the most powerful splitter I could find. good luck tom

I wouldn't try, this item is a piece of scrap metal, I've bought 2 and both broke, bought a welder and saved it.

Yes, the pump will fit your 3/4 hose. It is a very good pump for the money...powerful and very well made.Do not let it run dry as the impeller will burn up. Listen for the RPMs to go up, indicating your tank is empty. Turn it off.

Yes if you bevel it and most likely need to use a couple of passes, good for a occasional job but if doing a lot of 1/4" and larger welding would be better off getting a larger machine. This works well with 3/16" steel and smaller, really good on 1/8" steel and smaller. In most home welding you don't need a bigger welder. The rule is buy the best welder you can afford, and I would avoid the non name brand welders. Get a Hobart, miller or Lincoln to be sure it is a quality machine

I have done some welding on 1/4 steel, but not a lot, usually 3/16. But I have not had any problems on the 1/4, just a bit slower. I love this welder, since I can have it set up in my shop, and weld some stuff as it needs, Vs. the stick welder I have that I have to move outside to a 220v outlet. I'm not a good welder by any means, but with a little practice, I can weld really light stuff Vs. burning thru with the stick. The first time I used it, I thought I had made a mistake, since I had a har time welding, but the second day, after reviewing the settings again, I did, in my opinion, rather well. I also bought, quickly after, an auto dark helmet, as the arc is hard to see since it is small. I have done some welding on 1/4 steel, but not a lot, usually 3/16.

My plumber had to increase copper pipe to 3/4. This big of a unit needs 3/4

No. It's a little small I tried to do the same thing and it didn't work. I think it's 3/4"

Yes and no.... I used a small saw and cut out the middle section and it works perfectly for 3 quarts. But it is a solid piece and doesn't just pop out.

No its not suitable to weld much of anything. It will also Cost you more to setup for a tig package then it will to just buy a new lincoln welder.

My adapter will protect a pinch with a weld depth up to a little more than 3/4"

I have a 3/4 inch pipe coupled to mine and tried to stall it by gripping with both hands. Couldn't, it had too much torque, but may be too small for your job. Ernie Bruce

Yes. The dual in pipes line up like 99%, so a little 1% persuasion and it can be welded right up.

It is made for 4". It will not expand that much. Double check the size of your actual pipe (the pipe may start a couple of inches below grade) because the size you mention, 4-3/8", sounds odd to me.
