The BRAVO TIG 250 AC/DC inverter welder is built in IGBT technology for welding with the TIG AC/TIG AC PULSE/ TIG DC/TIG DC PULSE/TIG MIX (AC+DC) method on direct current (DC) or alternating current (AC), and with the MMA method using covered electrodes on direct current (DC). It is made for welding all metals, aluminium included.
The welder runs in 2-step and 4-step mode with non-contact (TIG HF) arc striking. It can store 10 individual welding settings in memory and is prepared for external control of its work.
The welder also runs the MIX TIG method, which brings together the benefits of welding on alternating current (AC), a very clean weld, with the deep penetration reached on direct current (DC). The result is a weld of very good quality on thin and on thick material. A soft control panel, one multifunction knob and a digital display of the working parameters make setting up simple and quick.
A clear control panel that allows the setting of:
gas pre-flow time before the arc is struck
, starting current
, welding current upslope time
, welding current
, base current (only in TIG DC PULSE mode)
, pulse width (duration) (only in TIG PULSE mode)
, pulse frequency (only in TIG DC PULSE mode)
, current downslope time
, end current
, gas post-flow time after the arc goes out
The AC waveform can be chosen (square shape, sine shape), so the weld and its look can be shaped precisely. The TIG DC PULSE function keeps thin material (under 1.5 mm thick) from burning through and keeps the material from discolouring (when welding stainless steel). Two carrying handles make it comfortable to change the place of work.
A broad set of functions and easy operation, recommended for workshop and industrial work.
