It's a loop technology. This enables to continuously adjust both the primary and secondary current such compensating any fluctuation of the mains supply or variation of the metal to be welded: this grants a constant good quality of the results.
Very good precision on the current control thanks to the double feedback both on the primary and the secondary circuit.
Reduction of operational and maintenance costs. To achieve the same welding result, a traditional AC system would require higher installed power and mains current. In addition, due to the shorter welding times, the electrodes maintenance is reduced and productivity is increased.
Excellent flexibility and adaptability to the materials to be welded.
Adjustment of the welding current per milliseconds. This enables a very precise adjustment of the welding process.
As compared to an AC welder, inverter medium frequency technology produces a much more efficient heat output and this allows to obtain the same welding result in a shorter time and to reduce the heat dispersion around the nugget (HAZ heat affected zone) without affecting the features of the material.
Very compact welding transformers (almost 50% smaller as compared to AC ones).
Inverter command with medium frequency IGBT, with possibility of choosing the operating frequency of the inverter between 1000 Hz and 4000 Hz.
