GB-3STV Double Tube Welding Gun

GB-3STV dual tube welding gun focuses on the overhaul of air conditioning refrigeration systems and the welding of large mouth copper pipes in industrial settings. It adopts a dual tube collaborative gas supply design and is compatible with MAPP gas or propane air mixed gas supply. It can output a 2700 ℃ high-temperature flame without additional oxygen and easily handle the welding of 10-24mm copper pipes and copper aluminum dissimilar materials, solving the problem of insufficient high-temperature coverage of ordinary welding guns.
The gun body is equipped with dual independent adjustment knobs, which can accurately control the gas flow and flame intensity respectively. Combined with an upgraded anti backfire device, it effectively avoids safety hazards caused by airflow fluctuations; The brass gun head is treated with anti-oxidation, high temperature resistance, wear resistance, and has a service life 35% longer than ordinary welding guns.
The anti slip rubber handle fits snugly against the grip curve, making it less prone to fatigue during prolonged operation; Equipped with a high-frequency rapid ignition system, it ignites instantly without the need for additional tools. Whether it is complex outdoor operations for maintenance teams or precise welding in small batches in factories, it can balance efficiency and safety, making it a cost-effective choice for medium to high strength welding scenarios.
