2.3 Brief Introduction
TIG series of welding machines 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, 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.
