Gary McCreadie HVAC/R Tech/Business Owner on Instagram: "Small but mighty... We are watching a demo of the @ambrocontrols Precision Torch that can braze up to an 1-1/8". I've been using this set almost exclusively over my larger oxyacetylene torches. They run off Mapp gas and O2 and provide enough heat to perform brazing in the field, as seen in the demo. We also get a glimpse of the light weight nitrogen tanks they offer as well. Bro at the end enjoyijg his Michelob Ultra has plans 😂. #hvac #h
