OWNER’S MANUAL
This welding machine is composed of the inverter MIG welder
power supply with variable voltage output external characteristics
manufactured with advanced IGBT inverter technology designed
by our company.
With high-power component IGBT, the inverter converts the DC
voltage, which is rectified from input 50Hz/60Hz AC voltage,
to high-frequency 20 KHz AC voltage; as a consequence, the
voltage is transformed and rectified. The features of this machine
are as follows:
• IGBT inverter technology, current control, high quality with
stable performance
• Closed feedback circuit, variable voltage output, great ability
of balance voltage up to ±15%;
• Electron reactor control, stable welding, low spatter, deep
penetration, excellent weld bead shape.
• Welding voltage can be preset, and the voltmeter displays
the preset voltage value when not welding.
• Both welding current and welding voltage can be observed
at the same time.
• Burn back time is adjustable.
• Slow wire feeding during arc starting, removes the melted
ball after welding offering reliable arc starting;
• Wire feeding part is separated from the welding machine
with wide welding operation range.
• Small-sized, light-weight, easy to operate, economical,
practical.
Unpacking your machine:
When unpacking, inspect carefully for any damage that may have
occurred during transit. Check carefully to ensure all the contents
on the list below have teen received in good condition
Included items:
Operating environment:
Adequate ventilation is required to provide proper cooling for
the machine. Ensure that the machine is placed on a stable level
surface where clean cool air can easily flow through the unit. The
machine has electrical components and control circuit boards
which will be damaged by excessive dust and dirt, so a clean
operating environment is essential.
LIFT TIG
Needed items: inverter welder with LIFT TIG function 2 Piece TIG
Torch with one output power cable and one Gas Hose.
The operation of LIFT TIG is shown as below:
The output power cable connects with the negative output
terminal, and the Gas hose connects with the gas regulator on
the gas bottle. There is a nut on the gas hose, which can connect
with the gas regulator. Then open the valve of the gas bottle and
open the valve of the gas regulator, you can control the gas flow
by adjusting the gas regulating valve on the TIG Torch. Make the
tungsten electrode touch the workpiece, lift the TIG Torch up, this
will produce the arc.
