temperature capability: The flame can reach 1300 degrees and can melt metals such as gold, silver, copper, aluminum and tin, but it cannot dissolve steel and iron. Long operating time: The flame of a cartridge gas cylinder can generally last for about 1.5 to 2 hours. Safe startup procedure: Before ignition, let the gas flow for two seconds and turn the gas valve back to the minimum. It is very easy to hit the fire source. Safe distance guidance: There should be a certain distance between the flame and the object. If it is too close, it will cause the local temperature of the nozzle to be too due to tempering. Compatibility: Designed for use with standard cartridge gas cylinders. Use scenarios: Jewelry making and repairs that involve melting gold or silver and reworking precious metals. Smallscale metalworking and soldering with copper, aluminum and tin components. DIY metal crafting and refurbishment tasks that require a precise heat flame.
