    Connecting generators in a series or a parallel circuit is forbidden. HARDWARE DESCRIPTION (FIG-1) The TIG 250 AC/DC is an Inverter welding unit to be used with refractory electrodes (TIG) in direct (DC) or alternative (AC) current. TIG welding requires gas shield protection of pure gas (Argon).

    TIG 250 AC/DC POWER SUPPLY-START-UP • This equipment is supplied with a 16A EN 60309-1 type plug and should only be used on a three-phase 400V (50-60 Hz) four-wire electrical instal- lation with an earthed neutral. The effective absorbed current (I1eff) is indicated on the equipment, for maximum use conditions. Check that the power supply and its protection (fuse and/or circuit breaker) are compatible with the current required for use.

    • Connect 5 - automaton mode: This mode enables to pilot the TIG 250 AC/DC from a console or from an automaton due to 5 pre-saved programs. For the foot pedal, the «Switch (D)» enables to start or stop welding according to the choosen cycle. The voltage value for the «slider (B)» matches a program or the actual statut.
