Technical
Data
Grand Tig 200 AC/DC Pulse PFC MV adopt the latest Pulse Width Modulation
(PWM) technology and the Insulated Gate Bipolar Transistor (IGBT) power modules.
It uses switching frequencies in the 20KHz-50KHz ranges so as to replace the
traditional line-frequency transformer type welding machines. Thus, machines are
characterized with portability, small size, lightweight, low energy consumption and
noise, etc. The parameters of the machine on the front panel all can be adjusted
continuously and steplessly, such as start current, crater arc current, welding current,
base current, duty ratio, upslope time, downslope time, pre-gas, post-gas, pulse
frequency, AC frequency, balance, hot start, arc force and arc length etc. When
welding, it takes high frequency and high voltage for arc igniting to ensure the
success ratio of igniting arc.
