Equipment structure:
The main control box, blower device, combustion support, and burning blowtorch four parts. The control box is removable.
Components, Materials:
The frame material is made of high-quality 304 stainless steel square welding, and the control box is made of (t=1.2mm) electrostatic steel plate, and the surface is sprayed with plastic, which is more smooth and beautiful.
Control system:
The control box adopts relay control system, and all electronic components are made of domestic leading brands, which can better ensure the working performance and detection accuracy of the machine.
The temperature adopts imported intelligent P.I.D thermostat (with automatic calculation function) and high-precision PT100 thermocouple sensor and timer.
The equipment has the following safety protection devices: power overload protection, short circuit protection, control loop overload protection, ultra-high temperature protection.
