~WSM series digital welding machine produced is changed to “ARV” (microcomputer controller) control from the analog control of traditional inverter welding machine (refers to the main part which influences welding machine).

Centralized Treatment of all welding data by Digital “ARV”. Control and monitor all the welding process by digital, make reaction for change of any welding process quickly. The monitoring system makes the digital comparison and adjustment timely for the actual welding parameters and the setting parameters, so the machine shows the incomparable welding accuracy so far.

Outstanding characteristic of WSM digital TIG welding machine:

1. Structure aspect
●Volume and weight (WSM-400 main engine only 38kg)   WSM series welding machine adopts the digital micro-processing technology combining with the high frequency converting technology, and decreases 20% electronic components.
● Fault self-diagnosis function  The welding machine can detect all the unnormal conditions of welding machine, such as the circuit voltage status of main engine connection automatically (open-phase, fluctuation),damaged part of the inner components of welding machine, and etc., which has a great significance for protecting the welding machine and timely deb ing (the welding machine has no fuse wire).
● Techniques in the setting function  Air supply in advance, rise time of striking current, constant current control, decay time of current, arc stopping current, gas delay, base current, peak current, duty cycle and pulse frequency are adjustable. Hua’ao welding machine doesn’t set up the corresponding button on the panel to influence the visual sense of operators, and it is set in the inner module of welding machine and can be moved out to adjust just like moving out from a computer.       
● Low –power and high-performance   The efficiency reaches 90% and the power factor reaches 0.89, which saves energy by more than 40% than general welding machine.
2. Operation aspect
● The panel adopts the intelligent design   Air supply in advance, rise time of striking current, constant current control, decay time of current, arc stopping current, gas delay, base current, peak current, duty cycle and pulse frequency can be realized by two buttons the function option and parameter option.
3. Welding performance aspect
● Most excellent welding quality    The heart of welding machine is the digital microcontroller that makes centralized treatment for all welding data, gives digital control and monitoring for the whole welding process, make reaction for change of any welding process quickly, and the arcing is especially steady.
● Exact arcing function   the welding machine has a method of high frequency, which makes a very high arcing success rate.
● Exact arcing function   the welding machine has a method of high frequency, which makes a very high arcing success rate.
● Suitable for multiple materials   Suitable for welding carbon steel, stainless steel, galvanized sheet, copper, and etc.
● Special four-step welding process   The arc striking and arc suppression current can be set exactly, which reduces the welding defect of arc striking and arc suppression greatly.
