Looks like a good idea for a permanent shop application. I know of a pro welder who uses Propane on his mobile truck instead of acetylene. Different fuels work well, just need different tips and the skills to know how.
I did not intend to cause any prior grief, lately been busy trying to keep the business alive despite the hacks who have been laid off in the city & cutting the throats of legit companies. I enjoy a spirited debate & apologize for not offereing some docs, been busy & dealing with the with the now passing of a very much loved uncle who has influenced my dealings in life very much. He was a simple, humble man without much book learning who worked very hard & posessedd a great wealth of common sense.
You cannot have more than one HVAC Proffesional in any enclosed area without a vigorous debate. That's very good for our trade.
I have seen that little unit which is just basically a compressor and it works pretty well. Normally there is Natural Gas onsite at say a hospital addition or renovation project, it does seem crazy to run temp lines for brazing but there is a lot of it on that type job. I have been in power houses where they have acetylene lines run through out the facility to tie into, in that case it wouldn't be much different to have Natural Gas in them.
