Explore the Advanced Capabilities of the RevoTig 400 ACDC
? Advanced AC Wave Control.
The RevoTig 400 ACDC offers unprecedented control over AC current characteristics. Users can choose from a variety of waveforms: rectangular for fast welding with good penetration, sinusoidal for soft arc and quiet operation, triangular for minimizing heat input in thin materials, and trapezoidal for optimal wetting and welding in forced positions.
In addition, precise AC balance adjustment (negative to positive electrode duration ratio, e.g. EN/EP in the range of -40% to +40%) allows perfect adjustment of oxide layer cleaning intensity (especially with aluminum) and fusion depth. Adjustable AC current frequency (20-300Hz) affects arc focus and welding speed.
пульс High Frequency AC/DC Pulse for Precision
The RevoTig 400 ACDC is equipped with an advanced pulse module that operates in both DC and AC modes. In DC mode, the pulse frequency can be adjusted over an extremely wide range from 0.1Hz to 3000Hz, allowing precise management of linear energy, control of the weld pool and the achievement of an aesthetic weld with a clear scale, even on very thin materials.
In AC mode, the pulse (frequency 20-300Hz) further improves control over the welding process of aluminum alloys, minimizing the risk of burn-through and distortion. Adjusting the base current, peak current and pulse fill factor (1-99%) gives the welder full tools to optimize the process for a specific application, from welding thin sheets to achieving deep fusion.
?️ Intelligent Support Features and Security
The RevoTig 400 ACDC has a number of features to make work easier and safer. The ability to save up to 50 individual welding programs (JOB) speeds up changeovers. The built-in VRD (Voltage Reduction Device) function in MMA mode reduces the idle voltage to a safe level, minimizing the risk of shock.
In addition, the TIG spot welding function with precise time adjustment (0.1-30s) is ideal for tacking. The unit is designed to work with an optional foot control for infinite current adjustment. A USB port allows easy software updates, and an optional SMARC interface allows integration with Industry 4.0 systems.
? Arc Stability from the Lowest Currents and MMA Welding
Thanks to its advanced power circuit design, the RevoTig 400 ACDC provides stable ignition and DC TIG arc welding as low as 3A. This is crucial when welding very thin parts, where precise control of the minimum heat input is essential to avoid burn-through and deformation.
The unit also offers full-fledged MMA (shielded electrode) welding mode with currents up to 400A. Features such as adjustable arc force (Arc Force) simplify the process, prevent electrode sticking and ensure a stable arc even under difficult conditions or long welding leads.
