Welding Equipment
Gas-welding equipment, necessary for the refrigeration plant is the following: oxygen cylinder, acetylene cylinders, regulators and gauges, hoses and a torch. Before performing any welding, local welding code should be thoroughly studied and understood. Never operate welding outfit near combustible materials. Never use excessive gas pressure. Heavy explosion may result.
Attention: Never use oxygen, acetylene, or any other welding fuel to create the necessary pressure in the cooling system pipes, pipelines, equipment. Carbon dioxide, nitrogen and argon are safe when used with a pressure regulator and a relief valve. They can be used to develop pressure in the refrigeration lines...
