1. Flame Control for Precision: The single switch spray gun features only one valve to regulate flame size. The dual switch spray gun includes a main switch for gas on/off and an auxiliary switch for finetuning flame size, enabling seamless transitions from gentle to intense flames and temperatures. Stable combustion is ensured by the copper core nozzle and wind shield design, maintaining flame stability even in windy conditions and preventing fluctuations in heat output. 2. Sturdy and Durable: Constructed with a robust metal frame, it resists temperatures without deformation and remains rustresistant for longterm use. The handle is wrapped in a nonslip, heatinsulating rubber sleeve, minimizing damage to critical components if accidentally dropped and extending its lifespan. 3. Convenient Setup: The kit comes with a 2meter hose made of flameretardant rubber with a steel wire braided layer, ensuring pressure resistance, explosionproof safety, and leak prevention. The threaded knob connection allows for easy installation, enabling quick and hassle operation. 4. Universal Compatibility: Compatible with various gases such as methane, butane, liquefied gas, and coal gas, this torch offers versatility and efficiency for all your burning applications.
