材料:20公厘厚的低碳钢,8×20公厘铜排做成导线。注意事项:1)两电极之间的距离以50～60公厘比较合适;2)启动电阻不要同金属坩埚接触;3)启动时把变压器转向开关调到第三挡;4)电阻取下后用第四挡或第五挡进行升温和加热;5)电阻回旋的上端要露出盐面一些。效果:在C—25盐炉上,把这个电阻放在两个电极之间,用第三挡启动 Material: 20 mm thick mild steel, 8 x 20 mm copper wire made of wire. Note: 1) the distance between the two electrodes to 50 to 60 mm more appropriate; 2) start the resistance do not contact with the metal crucible; 3) start the switch to the third gear when the switch; 4) after the resistance is removed With the fourth gear or fifth gear for heating and heating; 5) the upper end of the resistance swing to expose some of the salt surface. Effect: On a C-25 salt cooker, place this resistor between the two electrodes and start with the third gear
