The OTC VRTP400 welding machine features a variety of pulse mode functions that adapt welding to the shape of the workpiece for optimal results.
Its newly developed high-frequency generating circuit enables stable and instantaneous arc starting, with a minimum TIG welding output current as low as 4A.
The VRTP400 TIG welding machine includes a safety function that automatically stops gas flow if welding is not detected for over 2 minutes, preventing gas waste.
The remote control box has an automatic identification function, eliminating the need for manual panel switching, making welding condition settings more convenient.
The unique overlapping design stacks two machines by covering the upper power supply’s fixing feet with the lower power supply handle, saving space and improving portability.
It also supports an automatic machine terminal block and is equipped with comprehensive input protections, including over-voltage, low-voltage, and phase-loss protection, ensuring safe operation under various power conditions.
The built-in anti-electric shock function (switch-controlled) makes the VRTP400 suitable for welding in humid, high-altitude, and confined spaces. Its dust-proof structure allows reliable operation in harsh environments.
Additional features include a special arc end mode adjustment function for precise welding control.
