5. INSTALLATION DEBUGGING AND OPERATION

Note:
Please install the machine strictly according to the following steps.
Turn off the power supply switch before any electric connection operation.
The protection class of this machine is IP21S, so avoid using it in rain.

5.1 Installation method

1. A primary power supply cable is available for this welding machine. Connect the power supply
cable to the rated input power.
2. The primary cable should be tightly connected to the correct socket to avoid oxidization.
3. Check whether the voltage value varies in acceptable range with a multi-meter.
4. Insert the cable plug with electrode holder into the "+" socket on the front panel of the welding
machine, and tighten it clockwise.
5. Insert the cable plug with work clamp into the "－" socket on the front panel of the welding
machine, and tighten it clockwise.
6. Ground connection is needed for safety purpose.
The connection as mentioned above in 6.1(4) and 6.1(5) is DCEP connection. Operator
can choose DCEN connection according to workpiece and electrode application
requirement. Generally, DCEP connection is recommended for basic electrode, while no
special requirement for acid electrode.

5.2 Operation method

1. After being installed according to the above method, and the power switch being switched on,
the machine is started with the power LED on and the fan working.
2. Pay attention to the polarity when connecting. Phenomena such as unstable arc, spatter, and
electrode sticking could happen if improper mode is selected. Exchange the polarity if
necessary.
3. When switching the MMA/TIG switch to MMA mode, normal welding can be carried out under
rated output current. When switching the MMA/TIG switch to TIG position and using lift arc
ignition, arc can be successfully started under rated arc ignition current, and normal welding
can be carried out under rated welding current.
4. Select cable with larger cross-section to reduce the voltage drop if the secondary cables
(welding cable and earth cable) are long.
5. Preset the welding current according to the type and size of the electrode, clip the electrode
and then welding can be carried out by short circuit arc starting. For welding parameters,
please refer to 6.3.
