I do the same - where it falls apart is on lap welds - with this torch, you won't get any heat into the lower layer & the weld will either be crap or look like a dogs backside. Butt welds are a doddle with any semi-decent/total garbage small flame torch. Where it will struggle (I.e fail) is on vertical welds/lap welds as you will have to dwell too long leading to holes. If you say different & can show, then I bow to your superior skillz.

Looks almost like a TIG weld. WOW!

What is the coat of the torch with nozzle set

with kind off grip you use, and wich kind off gas you use sir?

Please tell me what is the equipment you are using! Thanks

Where can I buy this set it looks great 🏻

Tell me... How... I need this..

No WHAT? No GASES? Madness! What's that hissing sound? There's a flame being lit at the beginning. If it comes out of a generator ("Water Welder") then it's exactly Oxygen and Hydrogen, and maybe some alcohol that the mixed gases bubble through. Mine has that, I think it's standard. Also I think this is blowing too hard, and might benefit from a bigger tip and a softer flame. But that's a small thing.

What torch is that

TRY OXY AND HYDROGEN. IVE BEEN BURNING LEAD FOR 46 YEARS!!
