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.
