Oxygen-free welding torch as a necessary tool for refrigeration, the application is so hot!

As the saying goes, "if a worker wants to do a good job, he must first sharper his tools". As a necessary tool for refrigeration, welding torch is indispensable for installation and maintenance. The traditional welding torch has always had an oxygen bottle and a gas bottle, which is inconvenient to carry and troublesome to fill with oxygen.

　　Oxygen-free welding torchIt is based on this background in the refrigeration industry birth application. Oxygen-free welding gun does not require a special oxygen cylinder, the use of natural air in the oxygen and gas cylinder in the combustible gas mixed combustion, injection to form a heat source with a maximum temperature of 2400 degrees.

Copper is a product with relatively high thermal conductivity. The melting point required by itself is not low. The melting point of copper is 1,100 degrees. Is it enough for the welding torch temperature to reach more than 1,100 degrees? This is not the case at all. This requires consideration of heat radiation in space and heat conduction of auxiliary materials. When we introduced the first generation, we considered that the oxygen-free welding torch was directly applied to the refrigeration field.

Many oxygen-free welding guns abroad are not used for welding copper pipes. They have to consider many aspects, such as ease of use, such as electronic ignition, which cannot be ignited after the inflation reaches a certain level. Then, in the case of low air volume, the release of temperature and calorific value are relatively unfavorable, and there is no way to use it in the refrigeration industry.

and traditionalAerobic welding gunIn contrast, the oxygen-free welding torch does not have an oxygen cylinder, it only has a gas bottle and a welding torch, which is especially suitable for copper pipe welding, installation and maintenance of refrigeration, air conditioning and heat pump equipment, and has the characteristics of convenient carrying, simple and reliable operation, etc.

When welding copper pipes, only a can of hot gas (Manp gas) and an oxygen-free welding torch are required (no oxygen cylinder is required). A bottle of fierce fire gas weighs about 453g, and a small bottle of fierce fire gas can last for 50 minutes according to the maximum gas consumption of 9g for the fierce fire brand double-tube anaerobic welding torch. If you use the fierce brand single-tube anaerobic welding torch, you can weld for more than 1-2 hours.
