QQ300 air-cooled argon arc welding gun 3M-5M

The QQ300 air-cooled argon arc welding gun is a commonly used TIG welding gun, with 3M-5M referring to its cable length. Here is a detailed introduction:

performance parameters

Welding current: The rated welding current is usually 300A, and the welding current range is generally between 60-300A.

Load duration: Generally around 80%, it can meet the continuous welding requirements for a certain period of time.

Applicable tungsten electrode diameter: It can adapt to tungsten electrodes with different diameters such as 1.6mm, 2.0mm, 2.4mm, 3.0mm, 3.2mm, etc.

Cable specifications: Common ones include national standard 10 square, 14 square, 18 square, 22 square, etc. Different specifications of cables are suitable for different welding currents and working scenarios.

structural characteristics

Gun head: It is made of high-temperature resistant (based on actual reports) insulation material that has good insulation performance, can effectively prevent leakage, and has a long service life.

Cable: Copper wire is usually made of national standard oxygen free copper wire, which has low resistance, good conductivity, is not easy to generate heat, and can protect the stable transmission of welding current.

Tracheal: It adopts welded one-to-one rubber tubes, which have the characteristics of high temperature resistance (based on actual reports), high pressure resistance, aging resistance, etc., to confirm the stable delivery of argon gas.

Handle: Generally designed with ergonomics, it is comfortable to hold and easy to operate. Some welding guns are also equipped with welding switches, making it easy for welders to control the welding process.

Applicable scenarios

Metal processing: suitable for welding various metal materials such as stainless steel, aluminum alloy, copper, etc., and can be used in industries such as mechanical manufacturing, hardware processing, and automotive maintenance.

Mold manufacturing and attentive service: For the welding and attentive service of molds, QQ300 air-cooled argon arc welding gun can provide accurate welding control, protecting the quality and accuracy of molds.
