To ensure personal safety, inferior rubber hoses or other hoses that do not meet the requirements of corrosion resistance, pressure resistance, aging resistance shall not be used.
3. When igniting, always pay attention to the direction of the flame and do not face the human body or any flammable or explosive materials.
4. If the built-in tempering device has a lifespan, if the flame torch fails to backfire (sparks flash in the rubber hose), immediately repair or replace a new torch.
