Refrigeration Bad Weld Repaired; What is the difference between a proper repair and a patch to keep it running? This high pressure copper line was kinked and forcing the pressure to a point of rupturing the sidewall. The ‘other’ company just put a spot weld on it and walked away. Our Technicians at Pro Refrigeration LLC have higher standards. We cut out the bend and installed a standard long radius 90 degree elbow. This will lengthen the life of the walk in cooler at this soon to open Tasty s Restaurant in Pflugerville.
