NEW 30W 220V Welding Melting Machine Gold Silver Welding Melting / Soldering Maximum Temperature Up To 2000 Jewelry Welding Tool        Multifunctional Jewelry Melting Machine Voltage: 220V Power: 30W Flame temperature: 2000C Flame size: 70mm Air pressure: 0.4-0.6kg/cm2 Fuel consumption: 0.1-0.15kg/h Machine size: 26*17*15cm Machine weight: 4.3kg Basic profile It has the characteristics of small size, energy saving, low noise, high efficiency, flexible operation, complete functions, extensive operation and convenient maintenance. Especially modern jewelry factories, gold and silver processing, dentistry work rules This machine uses gasoline as fuel and consists of a low-pressure air supply pump and a gasification barrel. Add the right amount of gasoline in advance. & 12299;Exhaust pipe: connect the welding torch, and then plug in the 220 volt power indicator. When the power indicator light is on, it means the power is on. Press the corresponding switch and adjust the button according to the working air volume you need. You can light the torch and adjust the ''flame adjustment''. '' ''The blue flame is produced and begins to function. 3. Matters needing attention 1. It is strictly forbidden to add oxygen, hydrogen, acetylene, coal gas and biogas into the gasification barrel. 2. According to the needs of the work, the amount of refueling at one time must not exceed, and the amount of refueling is at most 0.5 liters. But if you add a sufficient amount of gasoline, don't stay for a long time, such as not moving or overnight. 3. When adding gasoline, pay attention to pouring it into the oil filling hole. Pour the used oil out of the filler hole. Do not penetrate the body to avoid damaging the ring. 4. When the ''flame adjustment'' is repeatedly adjusted and the adjustment key does not produce flames, an appropriate amount of gasoline should be added. 5. The working time of this machine cannot exceed 6 hours. If working for a long time, the two machines should be used alternately to avoid overloading and damage to the rings. 6. When the newly added flame is not concentrated and the flame is red, you can properly adjust the ''flame adjustment'' to produce your own satisfactory flame. 7. When pumping waste oil, screw the oil pipe nut to the oil hole, then turn on all the switches, and the waste oil will be ejected automatically.
