Any fabricators using the DcH2000 cobra

i pre drill and even machine the oring land in all my intakes

the flanges are done on a cnc mill then they are welded and we chase the tapped holes after welding

mind you i jig tack all my production manifolds then weld them on a turn table

i still free hand weld prototypes

with a single pipe straight flange it is easy to do all machining on flange face after welding
takes care of any pull on the ears as well
 
i guess i have flanges both ends for spigot mounts or 2 into 1 manifolds plug the pipes/flanges are at angles

We had to brush the flux on to break the oxide layer down

hopefully Zeke will have less primitive equipment in the future...but he thought it was easier than doing the steel

dad is the black belt of flux core welding. Also some carb mounts are close to finished.

Hey guys we have been having our welding wars dad vs son. Zeke has been winning the war but the old man has picked up a win here and there. I wanted to pass on some literature courtesy of our Federal Govt. http://www.faa.gov/regulations_policies/handbooks_manuals/aircraft/amt_airframe_handbook/media/ama_Ch05.pdf

Page 12 I had laminated for Zeke it has all the torches with their nozzle sizes for both aluminum and steel which is handy

We have been welding on .050" 3003 for practice. We just take the shears and both take turns. We are just now getting better penetration and the hang of seeing the puddle and we haven't been blowing holes

I have one of the corbra torches. really like it. it works well on aluminum but, does take a bit of practice like everything else.

Welds steel pretty easy and doesn't use a ton of gas which is a plus. less distortion on sheet metal too since you can get a real small flame.

I think it works better than just a regular torch for sheet metal anyways.

the great thing about the cobra and other small oxyacetylene torches is that you can planish the aluminum weld http://youtu.be/etIQ-POUW28

My son has a beginner tutorial for oxyacetylene welding aluminum http://youtu.be/upE-sOIHjGo
