This video is about PWM company welder universal main board for MMA, TIG, MIG, MAG welding technologies.

Power electronics manufacturing & electronics service is the main activities of the PWM company.

The PWM company produce high power welding machines based on modern high frequency energy conversion.


The power inverter board model PWM-W1 cab be used for many devices with powering from One phase AC outlet, generating high power and current output

  1. Arc welding of different types – is the mainstream use of the board
  2. The board can be used ar powerful battery charger & cars motor starter
  3. The board can be used as source of stabilized DC power for any purposes

The PCB Main-Board overview

Here you can see now welder PCB main board ready for the serial production. The board is designed for modern computerizing manufacturing using Gerber format.

Welder main board model PWM-W1 have small size but allow to build different welding types up to 10 kilowatts power.

All PWM company’s inverters are designed for industrial and consumers markets.

The different models of welding machines are based on the same main board plus some signal and control small boards.

This is why we call this board – universal. It means for different purposes.

Welder have many of protection systems for long & reliable device work.

For the best protection welder board have analog protection block & digital protection block.

It means double protection, which significantly increasing inverter safety & long life durability of the device.

You can see that the main board have three big connectors:

  1. For LED panel errors indicator
  2. For Potentiometers regulation board
  3. For connection to microprocessor board with TFT or LED display.

Connection to micro-controller allow digitally control the welding machine and this significantly increase the quality of welding.

The Firmware for the welding machine can be downloaded from official PWM website and updated by device user via micro-USB port of welder.

USB port also provide connection ability to any computer for information display & for testing.

Welding main board is the first PWM company product. This product is designed also for internal use of company for Solar inverters production as high power DC power source. Company needs high power DC sources for emulation of accumulator batteries. This allows to test and manufacture solar off grid devices.


Welding inverters are produced for global world market. Sales worldwide for consumers & industrial markets. Own service center for repairing and warranty.


  1. Great performance & stability of output
  2. Great reliability
  3. Not bad quality like China-made inverters
  4. Not expensive like USA-Germany-UK-made inverters
  5. Digital control & protections
  6. Analog hardware control & protections
  7. Big TFT display with touch screen 2.8 inches (like in mobiles phones)
  8. Upgradable Firmware for inverter micro-controller
  9. One standard Main-Board for many appliances – universality & fast repairing
  10. Low cost & the same time modern electronics components – profitability & fast repairing
  11. Warranty in PWM service center(s). Chinese inverters without real warranty


Manufacturing of modern Power electronics is very profitable business. Calculations of profitability per 1 unit made in the PWM company investment presentation shows profitability from 200% to 2000%. Profitability depends of a lot of factors. You can check for more details in PFD document. The link is below.
