NON-CONSUMABLE ELECTRODE ARC-WELDING METHOD

A non-consumable electrode arc-welding method is provided for causing a welding machine (WM) to output or stop a welding current (Iw) in accordance with at least an ON state and an OFF state of a start signal. In the method, a start signal (Ts) is switched between an ON state and an OFF state, there...

Beschreibung
Zusammenfassung:	A non-consumable electrode arc-welding method is provided for causing a welding machine (WM) to output or stop a welding current (Iw) in accordance with at least an ON state and an OFF state of a start signal. In the method, a start signal (Ts) is switched between an ON state and an OFF state, thereby controlling the on/off operation of the welding machine (WM). Further, an operation mode instruction signal (Ms) is switched between a normal mode and an interval mode, thereby controlling the operation mode of the welding machine (WM). When the operation mode instruction signal (Ms) indicates the interval mode and also the start signal (Ts) is in the ON state, the welding current (Iw) is outputted in a welding current output period (Os). Then, the output of the welding current (Iw) is suspended in a welding current interval period (Fs) successively following the welding current output period (Os) .
