Please read this manual carefully before using this machine,

and keep it for future reference Application Precautions The roofing hot air welder LST-WP1 is of advanced heating technology and large welding pressure. And it is powerful, stable and easy to be operated, which is suitable for PVC, TPO, EPDM, CPE and other polymer waterproofing membrane constructions. 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 air duct and nozzle(during welding work or when the welding machine has not completely cooled down), and do not face the nozzle to avoid burns. The power supply voltage must match the rated voltage (230V) 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.

Using bottoms to set the required temperature. You can set the temperature

according to the welding materials and the ambient temperature. LCD display screen will show the setting temperature and the current temperature. 2. Welding speed: Using bottoms to set the required speed according to the welding temperature. LCD display will show the setting speed and the current speed. ● The machine has a memory function parameters, namely when you use the welder next time, the welder will automatically use the last setting parameters without having to re-set parameters. 32-Temperature Rise Button 33-Temperature Drop Button 34-Speed Rise Button 35-Speed Drop Button 36-Machine Walk Button 37-Current Temp. 38-Setting Temp. 39-Current Speed 40-Setting Speed 41-Power ON/OFF 32+33- Press Simultaneously Turn OFF/ON Heating

① Turn on the machine, and the LCD display screens are shown as above. At this

time, the air blower does not heat and is in the state of blowing natural wind. ② Press the buttons Temperature Rise (32) and Temperature Drop (33) at the same time. At this time, the air blower starts to heat up to the setting temperature. When the current temperature reach the setting temperature, press button Speed Rise（34） to set speed. The LCD screens are shown as above. ③ Pull up the Blower Location Handle (30) , raise the Hot Air Blower (8), lower the Welding Nozzle (3) to make it close to the lower membrane, move the air blower to the left to insert the welding nozzle into the membranes and make the welding nozzle in place, At this time, the welding machine automatically walks for welding. The LCD screens are shown above. After completing the welding work, remove the welding nozzle and return to the initial position, and press the buttons Temperature Rise (32) and Temperature Drop (33) on the control panel at the same time to turn off the heating. At this time, the hot air blower stops heating and is in cold air standby mode while allowing the welding nozzle to cool down after waiting for the temperature to drop to 60°C, and then turn off the power switch. ④ Pay attention to the position of the Guide Wheel (21) at all times. If the position deviates, you can touch the Operating Handle (25) to adjust.
