Precautions
Parameter
Please confirm that the machine is turned off and unplugged before disassembling the welding machine, so as not to be injured by live wires or components inside the machine.
The welding machine generates high temperature and high,heat, which may cause fire or explosion when used incorrectly,
Especially when it is close to combustible materials or explosive gas, Please do not touch the hot wedge (during welding work or when the welding machine has not completely cooled down) so as not to burn
The power supply voltage must match the rated voltage marked on the welding machine and be reliably grounded. Connect the welding machine to a socket with a protective ground conductor.
In order to ensure the safety of the operators and the reliable operation of the equipment, the power supply at the construction site must be equipped with a regulated power supply and a leakage protector.
The welding machine must be operated under the correct control of the operator, otherwise it may cause combustion or explosion due to high temperature.
It is strictly forbidden to use the welding machine in water or muddy ground, avoid soaking, rain or damp.

Steps For Machine ON/OFF
1、Connect the power supply, lift up the pressure handle (1) and the pressure roller (5) to separate automatically, and press the power on/off switch(11).
2、Check whether the voltage value displayed on the voltmeter (14) is normal.
3、Turn on the temperature controller (9), set to the temperature required for welding, and wait for the temperature to reach the preset value.
4、Turn on the motor switch (13) and set the speed control knob (15) to the required figure.
5、Place the welding machine and insert the membrane layers.
6、Put down the pressure handle（1) ，the machine starts to move and weld.
7、Keep observing the welding trail and the position of the upperlayer and lower layer sat any time to adjustincase of deviation.
8、After finishing welding, lift up the pressure handle (1), and move the machine away from the welding position.
9、Turn off the motor switch (13), turn off the temperature controller (9), the hot wedge stops heating.
10、Turn off the power switch (11).
