Any fabricators using the DcH2000 cobra

Can't is a four letter dirty word
We are about to pull the trigger on the Dch2000 cobra torch. http://www.cobratorches.com/ Have y'all used one? All the reviews have been stellar for welding and cutting thin sheet metal-aluminum, stainless, and good ole steel. Can't afford TIG and we have a flux core but we have plenty of time to practice and become proficient. We know the low pressure regulators are paramount and have found that National sells the American made low pressure regulators at half of what Cobra wants for them. http://www.nationaltorch.com/Series2500.html
 
Is that an updated version of the old Dillon torch? Tinmantech uses something similar and a buddy of mine has tinman's Meco Midget. It is less pretty but welds beautifully. He welded all his 4130 tubes for his plane with a Meco midget.

I use a cheap assed ebay knock off of a regular old school welding torch and my bad welds are just the welder not the equipment.

Yes it is the Dillon...down under timeless technology. It became the henrob 2000 now it is the cobra dhc2000. I have been looking at tinmantech, the Meco Midget and it may be easier for Zeke to use. It also had more versatility for welding in different positions than the Cobra. The aircraft guys seem to like it! One of the secrets to welding with it is moving slow and puddle management. What I like about both of them is that they will teach some old school skills and patience. We are constructing a shed with concrete floor and metal sides to house our welding gear...need to do more research. We also do some landscape art and it would be nice to cut without buying a plasma cutter.

i tried one years ago, it was a new dillon,i dint like the pistol grip, we put it back in the box and just continued to use a standard oxy acetylene welding outfit

"Landscape art" - That's what my welding looks like at times. :-)

can you imagine what our welds would look like if we had started at 10 with the right instruction? http://www.tinmantech.com/html/kent_white.php looks the the meco midget is edging ahead. I wonder if the flame is soft enough to weld aluminum cans?

thanks xb33bsa they seem to be heavy moving toward the meco midget.

they are a gimmick in my opinion, maybe good for certain jobs but a standard welding outfit is your'e best bet you can weld aluminum with a regular torch but it takes great skill to weld aluminum with ANY flame
welding with a regular torch is more similar to a tig torch as well ie hand position

edit i gurgled a meco midget looks much more "handy" ;)
anyway you go, flame welding is the first important one to have being able to heat metal is almost as important as being able to weld it,brazing is a hugely important and useful skill to learn for fabricating as well

xb33bsa what flux and what welding glasses have you used for torch welding aluminum?

hah i have never torch welded aluminum,but have looked into the process and talked to a few old timers that have done it, at the time i just went to tig instead
personally i have only ever welded steel and cast iron with the torch flame

Here is what we have learned from our research:
It is hard to see the puddle form and Tinmans welding glasses and flux seem to be the key and also are paramount to protecting the eyes https://www.tinmantech.com/html/tm2000.php

The dhc2000 provides a more concentrated flame for learning and has the added benefit of looking like a gun ;)

Many have tried to weld aluminum with a standard torch and the learning curve is steep and requires many hours of practice. We have watched Sean of Roc City http://youtu.be/71I9pbyDFTU and he makes it look easy because he is in the majors and we are in pee wee league.
 
i have had a dillion for over 20 years and for some apps it is awesome

cutting and brazing/welding its great i dont like welding aluminum with it and since i have mig and tig i dont

have to

cxman one day he will have a tig. What applications do you use your Dillon most? What do you think about learning on one? The hand position and methodology seem to be the same as TIG. My son learned TIG in about 10 minutes. http://youtu.be/3fKlIpBbYk0
We were with the guys at Revival Cycle this weekend and they thought it would be a good discipline to learn on the torch.

i am a little old school and do a lot of lead body work i use the dilion for that

i love it for cutting (i dont have a plasma cutter)

i do a fair amount of braising still so it gets used for that as well
 
I don't understand the difficulty in seeing the aluminum puddle. It just looks like shiny aluminum instead of red like steel.
