pulsing:? Precision DC TIG Pulse Control for Optimal Quality
The MEGMET RevoTig 400DC offers an advanced pulse DC TIG welding mode, enabling the welder to precisely control the energy introduced into the weld. The pulse frequency adjustment range from 0.1 Hz to as much as 3,000 Hz allows the parameters to be perfectly matched to the materials and thicknesses being welded. Low frequencies (0.1-10 Hz) provide a wide arc, ideal for positional welding, while high frequencies (10-3000 Hz) concentrate the arc, reduce heat, and enable fast welding of thin sheet metal and fillet welds.
In addition, an adjustable pulse width of 1-99% allows precise shaping of the weld pool and fusion depth. This flexibility translates into minimized distortion, excellent weld appearance (scale effect) and the ability to weld very thin materials (even from 0.3 mm stainless steel at 3A current) while maintaining their mechanical properties.
⏱️ High-Stability TIG Spot Welding
The TIG spot welding function of the RevoTig 400DC has been optimized for repeatability and precision. It allows the spot welding time to be set from 0.1 to 30 seconds, with adjustment steps of 0.1 seconds. This ensures a stable arc and perfectly consistent weld points.
This feature is invaluable for tacking parts before basic welding, assembling precision structures, and for work requiring high accuracy and aesthetics. The ability to precisely set the duration of the welding pulse minimizes the risk of burning through material, especially with thin sheets.
?️ Advanced MMA Features with VRD and Arc Force Control
The MEGMET RevoTig 400DC is not only a precision TIG welder, but also a powerful MMA welding machine. It is equipped with the VRD (Voltage Reduction Device) function, which reduces the idle voltage to a safe level, minimizing the risk of electric shock during electrode changes, especially in humid environments.
The adjustable Arc Force (arc dynamics) function allows the welder to adjust the arc characteristics to suit the type of electrode and welding position. Increasing Arc Force prevents electrode sticking and provides a deeper fusion, while decreasing this value produces a softer arc, ideal for thin materials and welding in forced positions.
? Intelligent Management and Updates via USB
The RevoTig 400DC is equipped with a practical USB port that significantly expands its functionality. It allows easy updating of the device’s system software, providing access to the latest enhancements and MEGMET-developed welding processes. Personalized welding programs or specialized characteristic curves can be uploaded directly from the USB memory stick.
In addition, the device has a memory for 50 individual welding programs (JOB). The welder can save optimized settings for frequently performed tasks and quickly recall them, reducing preparation time and guaranteeing repeatable weld quality. Optional integration with the SMARC IoT system allows remote monitoring and management of the welding process.
