2.1 Introduction
Congratulations for your purchase.
The welding machine is a rectifier adopting the most advanced inverter technology.
The development of inverter gas-shielded welding equipment profits from the development of the inverter
power supply theory and components. Inverter gas-shielded welding power source utilizes high-power component
IGBT to transfer 50/60HZ frequency up to 50KHZ, then reduce the voltage and commutate, and output
high-power voltage via PWM technology. Because of the great reduce of the main transformer’s weight and
volume; the efficiency increases by 30%. The appearance of inverter welding equipment is considered to be a
revolution for welding industry.
AC/DC series welding machine are the AC/DC two-way machines, which are developed by our company
newly. Its biggest characteristics is that DC function can be used to weld stainless steel, alloyed steel, carbon steel,
copper and other color metals and AC function can be used to weld aluminum and aluminum alloy materials, such
as welding of scooters, bicycles. Main models are TIG200DPACDC。
AC/DC series machine adopts our company’s exclusive HF inverter technology. Compared with traditional
machine, it is compact in volume, light in weight, effective in transfer, power-saving; com pared with imported
machine, it is low in price, strong in power net adaptability. What’s more, it adopts twice inverter technology, has
characteristics of pure square wave output, good arc force, wide cleaning range and continuous arc with small
current, which guarantee excellent welding result.
AC/DC series are also with pedal current adjustment device . With that welder can free their hands to adjust
current by foot; And at the beginning of welding and at the moment of adding wire, it can increase current to heat
quickly; At the end of welding it can decrease current that is good for welding lines shape. With the help of pedal
it can improve welding efficiency, reduce welding difficulty and guarantee welding quality.
Thanks for purchasing our company product and hope for your precious advice. We will dedicate to
produce the best products and offer the best service.

3 Installation
The welder is fitted with power voltage compensation device. When power voltage changes
with
in a range of 15% of rated voltage, it can go on with the operation.
If a longer cable wire is used, , we suggest using cable with greater cross section in order to
reduce line loss voltage; if a connecting cable is too long, it may exert a great effect upon the arc
starting of the welder and other performance of the system, such as weakened high-frequency arc
starting or failure of the system to work regularly. So we suggest that you use recommended
configuration length.
1、Make sure that the vent of the welder is not covered or plugged to avoid failure of the
cooling system.
2、Protective gas source should be connected well. Gas supply passage should include gas
cylinder, argon decompression flow-meter and gas pipe. The connecting portion of the gas
pipe should be tied up with a hose clamp or other objects to prevent leakage and air intake.
3、The shell should be grounded reliably with a conducting wire with a sectional area not less
than 6mm2.
4、The quick plug of the loop cable is inserted into the quick socket of welder surface plate with
the polarity of “+” and tightened clockwise. The ground wire pliers at the other end hold up
the work piece.
5、When the pedal switch is used to control, Connect the 2-core aviation plug and 3-core
aviation plug of the pedal switch with the 2-core aviation socket and 3-core aviation socket.
6、Based on the input voltage class of the welder, the power line should be connected to the
distribution box of corresponding voltage class and non-corresponding connection should
never occur . Make sure that error in power voltage is within a permissible range.
7、Manual welding correctly as shown in the figure. Connect the copper nut from the other end
of the welder with the gas electric integration from the front panel, and tightened clockwise
firmly.
After completion of the above job, installation of the welder comes to an end and welding
can begin.
