1.1 Brief Introduction
E161, E201, E221, E301, E401 welding machines adopts the latest pulse width
modulation (PWM) technology and insulated gate bipolar transistor (IGBT) power module,
which can change work frequency to medium frequency so as to replace the traditional
hulking work frequency transformer with the cabinet medium frequency transformer. Thus,
its characterized with portable, small size, light weight, low consumption and etc.
E161,E201,E221,E301,E401 STICK machines Characteristics:
◆
MCU control system, responds immediately to any changes.
◆
high voltage for arc igniting to ensure the success ratio of igniting arc.
◆
Lift TIG operation, If the tungsten electrode touches the workpiece when welding,
the current will drop to short-circuit current to protect tungsten.
◆
Pedal control the welding current.
◆
IN DC TIG operation electrode touches the workpiece when welding, the current
will drop to short-circuit current to protect tungsten.
◆
piece
more than 2 seconds, thus the output current come down to around 20A in
order to easily seperate the electrode and electrode holder to protect the welder .

1.2 Working Principle
230V
The working principle of E161/E201/E221/E301/E401 welding machines is shown as
the following figure. Single-phase 230V work frequency AC is rectified into DC(about
312 V), then is converted to medium frequency AC (about 20-40KHz) by inverter device
(IGBT module), after reducing voltage by medium transformer (the main transformer) and
Meanwhile, the welding current parameter can be adjusted continuously and steplessly
to meet the requirements of welding craft.
Anti-Stick
function
automatically appeared when the electrode stick to the work
rectifying by medium frequency rectifier (fast recovery diodes),then is outputted DC .The
circuit adopts current feedback control technology to insure current output stably.
