Good afternoon chaps.

I have just found out that a job we are starting doesn't allow acetylene on site. How do I braze the big pipe on my VRV?
What would you use if you had to change a compressor?

Sorry for the schoolboy questions but I've always used oxy/acet on pipes 3/4 and up and only ever used it on comp changes & VRV/VRF connections.

Cheers
