Variable output frequency is a strategic choice when welding stainless steel tubes or pipes with a severe range of wall thickness and OD.
Variable output frequency is a strategic choice when welding stainless steel tubes or pipes with a severe range of wall thickness and OD. The adaptive circuit solution is able to guarantee the constant available reactive nominal power, independently from the working frequency value selected. The ideal load matching capability is auto-tuned independently from the selected frequency value. A dedicated PLC software adapts the inductance and capacitance in respect to the operator’s frequency selection.
