Welding Machine for miniature products
PW-28T Temperature Control Pulse Heat Unit
PW-28T is a high frequency inverter welder. It controlled by multi-processor and power IGBT, which makes it possible to exercise precise control over applied voltage, pressure, current and reflow temperature during each operation. PW-28T greatly reduce the training period of workers from weeks to just few hours. On the environmental side, no chemical solvent and insulation removal is needed, which also saves costs and labour. The device? enjoys low voltage (<2.5V) operations and low energy consumption.
.
Specialties:
Spot Welding mode:
PW-28T is a compact size lead free device capable of handling the welding needs of very fine wires ranging 0.02mm-0.5mm.
The product utilizes the principle of high temperature welding. Current flowing through the welding tip creates a high temperature to burn off the wire insulation, and then continues through the exposed wire and the metal base to weld the two together.
Welding quality is assured by closed-loop control for welding voltage and current.
Temperature Control mode:
W-28T embedded temperture control module, it operate as a Hot Bar Reflow soldering machine. Large current flowing through the high resistance material such as Mo or W etc. and generate heat. The heat was controlled by feed back of thermocouple on the heater tip accoring to the preset temperature and time.
Soldering quality is assured by closed-loop control for welding voltage and temperature.
Suitable for . . .
- Replacement for soldering, especially suitable for miniature component, flexible circuits, ribbon cables, flex to PCB...
- Welding (Soldering) with enameled wires. No need for wire stripping.
- Printed circuit board (PCB) repairs.
- Welding (Soldering) assortment of electronic components and surface-mounted components.
- Jobs requiring thin soldering layer.
Unique Features:
1. The large touchscreen provides easy access to all weld parameters in addition to a visual representation of the weld waveform graph, weld histograms, alarms, and warnings.
2. Quality of ordinary soldering or even welding jobs can only be visually estimated by tensile? strengths. Our unique current and temperature sensing and alert system ensures quality of each welded joint.
3. Specially designed micro-controller unit (MCU) with 9 programmable weld schedules with sequential
function.
4. Independent welding current and voltage detect system.
5. Single or Dual welding pulse output for different products.
6. Presettable discharge counter and alert syste
7. All welding data can be recoded in computer througth RS232 port for traceable and SPC purpose.
8.Electronic pressure sensing technology offers higher precision than comparable products with
mechanical pressure sensing technology
