H01 Series Oxy Acetylene Injector Welding Torch | H01-6 H01-12 H01-40 Long Neck Welding Blowpipe

1. Product Overview
Our H01 series injector-type oxyacetylene welding torch is a classic Chinese standard industrial blowpipe, widely recognized and purchased by global clients from Southeast Asia, Middle East, Africa and South America. Adopting advanced injector suction structure, this welding torch can work normally with low-pressure acetylene, propane and other fuel gas, greatly lowering users’ gas source requirement. We supply standard original size as well as customized extra-long 1000mm & 1200mm H01-40 long neck versions for deep welding, boiler maintenance, pipeline inner repair and narrow-space working scenarios. All torches pass strict air tightness test before factory delivery, stable flame, durable service life.
2. Core Product Features
✅ Professional Injector Suction Structure
Classic ejector design ensures stable gas mixing ratio, even if fuel gas is low-pressure, the torch still keeps uniform and steady welding flame, no flame off or backfire easily, much safer than equal-pressure type blowpipe.
✅ Premium Solid Brass Construction
The whole valve body is forged from high-purity brass, CNC precision machining for valve core, tight sealing to avoid gas leakage under long-time continuous work; seamless copper pipe neck is anti-deformation, high temperature resistant, not easy to crack.
✅ Multi-specification Full Range Selection
3 core models H01-6/H01-12/H01-40 cover thin sheet to thick metal welding from 0.5mm up to 40mm; H01-40 supports two extended lengths: 1m and 1.2m, solving difficult welding on deep boiler, long pipeline, container inner wall where common short torch cannot reach.
✅ Heat-insulated Non-slip Handle
Red rubber coated handle effectively isolates heat conduction during high-temperature welding, prevents scalding; ergonomic grip reduces hand fatigue after all-day handheld operation.
✅ Interchangeable Welding Tips
Each model matches different sizes of replaceable copper welding nozzles, users can swap tips freely to adjust flame size for different metal thickness, flexible for diversified welding work.
✅ Wide Gas Compatibility
Compatible with acetylene, propane, liquefied gas, coal gas, multiple fuel gas choices help clients save raw material cost according to local available gas resource.
