I think you might mean Motolife313's pressure vessel not OPUS's.

Try turning your heat up about 5 amps. It should flatten the bead slightly. Generally you clean the slag off before continuing the weld or doing a...

I plan to run it off our generator so I will have 240v with that I just have to buy the right pigtail to go from the generator plug to the machine. I...

or 4 compression springs. kinda like minertature front end coil springs, to give kids a moving like rocking effect

Th We have some 1/4" laying around, but we don't have a 240v outlet in our shop so I can't practice on that. I figure if I can get it down on 1/8"...

But it’s so easy to get carried away when having fun under the hood (for a novice like me, at least)! Like I did here:

Some advice I was given on here was to limit which joints I weld if strength wasn’t required, to limit distortion. I used this approach recently on a...

To be clear, lots of differences between steel and aluminum- both in technique and machine requirements. I expect you know that but not knowing your...

Welcome to the forum.

No matter the material we use for structure, I always add a weep hole. For Aluminum it is required to get a decent 100% weld, and on steel it allows...

Brackets to support an 86 gallon well pressure tank on my concrete wall. Spent 2.5 hours making them, but will forever have another 4 square feet of...

Emmmm, no thanks. Don't like clicking on suspicious links.

Won't argue that the area that failed was not the best application of this tube. But this structure was designed and engineered and to this point has...

Steel, .065, 1”. Clamp everything as true as you can. It is fairly easy in these sizes to bend back to flat after welding and grinding. After it is...
