QQ150 air-cooled argon arc welding gun (3M-5M specifications) is a TIG welding tool that focuses on lightweight and versatility. It adopts air-cooled heat dissipation design and is suitable for low and medium current welding scenarios. It is widely used in small and medium-sized machining and maintenance operations. The following is its detailed product information:
1、 Core performance parameters
Welding current: rated high current of 150A, normal working current range of 80-140A, suitable for medium and low load welding requirements;
Load duration rate: 60% (stable operation at 150A, meeting continuous operation requirements);
Applicable tungsten electrode diameters: 1.6mm, 2.4mm, 3.2mm, covering most thin plates and medium thickness materials for welding;
Cable length: 3M, 4M, 5M standard specifications (longer sizes can be customized) to meet different operating radius requirements;
Cooling method: air-cooled, natural heat dissipation through argon gas flow, no need for additional water cooling system, simple structure and easy maintenance;
Weight: 3M model weighs about 1.8-2.0kg, 5M model weighs about 2.3-2.5kg (including cables and basic accessories), lightweight and easy to operate;
Certification standards: Some models have passed CE, RoHS, ISO 9001 certification and comply with industrial welding safety standards.
2、 Structure and core components
Cable configuration:
The regular model uses a 16 square copper core cable with stable conductivity and low heat loss; The heavy industry model can choose a 25 square meter cable, which is suitable for high current and long-term operation, and is not easy to overheat;
The outer layer is wrapped with industrial protective cloth cover or wear-resistant (based on actual reports) rubber, which is resistant to pulling, splashing, and extends the service life.
Gun head and key components:
Gun head material: High strength aluminum alloy or copper, some models offer optional appearances in yellow, black, blue, etc., divided into integrated and split types (gas electric split design for easy maintenance and replacement);
Ceramic nozzle: High temperature resistant (based on actual reports) (based on actual reports) ceramic material, excellent protection of welding areas, isolation of splashes, and adaptability to different tungsten electrode specifications;
Tungsten electrode clamp: Copper conductive clamp, firmly clamped, confirming stable current conduction, suitable for 1.6-3.2mm tungsten electrodes;
Tracheal: Some models use silicone tubing, which has strong flexibility and aging resistance, smooth argon gas delivery, and protective effect.
Handle design:
Ergonomic grip, made of sliding insulation material, with good insulation effect, making it less prone to fatigue during long-term operation;
Integrated welding switch, easy to operate, user-friendly for beginners, some models support spot welding function, with meticulous arc initiation.
3、 Applicable scenarios and compatible devices
Applicable industries:
Light industry manufacturing: welding of small steel structures, hardware accessories, and stainless steel products;
Thin plate welding: excellent welding of galvanized sheet and stainless steel sheet (thickness 1-6mm), with uniform welds and minimal spatter;
Repair and DIY: automotive parts welding, equipment partial repair, metal crafts production and other scenarios;
Device adaptation:
Compatible with most TIG argon arc welding machines, such as TIG 160, TIG 180, TIG 200, TIG 250 and other models, with strong interface universality and smooth connection without poor contact.
4、 Core advantages
Lightweight and portable: The air-cooled design does not require additional water cooling circulation devices, making it lightweight and flexible to move, suitable for outdoor repairs or small and medium-sized workshop operations, reducing the burden of equipment carrying;
Easy maintenance: The structure is simple, the accessories (ceramic nozzle, tungsten electrode clamp, conductive nozzle) are easy to purchase, the replacement is fast, and the maintenance cost is low;
Good cost-effectiveness: As an entry-level to industrial grade transitional model with good cost-effectiveness, it balances performance and price, suitable for welding beginners, small factories, and repair shops to use;
Strong practicality: Copper core cables, high temperature resistant (based on actual reports) components, and protective cloth cover designs enhance wear resistance and high temperature resistance, extending service life.
