9 Installation and operation
Notice:
• Please install the machine strictly according to the following steps.
• Turn off the power supply before any electric connection operation.
• IP21 enclosure protection grade, and please do not operate it in rain.
9�1 Installation
1. Please connect the primary power line to the according voltage class. Please make sure the power line is connected to the
right voltage class.
2.
Please make sure the primary source is in fine contact with the according power line terminal or socket and prevent
oxidation.
3.
Detect the input voltage with multimeter and make sure the values are in the fluctuation range.
4. Please insert the electrode holder cable plug into the front panel’s upper “+” socket, and screw tightly clockwise.
5. Please insert the earth clamp cable plug into the front panel’s under”-“socket and screw tightly clockwise.
6. Please make sure the supply is in good ground condition.
9�2 Operation
1. After the correct installation per above methods, please turn on the power switch (“ON”). While the power supply is “ON”,
the welder start to work normally with the indicator lighting up and fan working( fan working is determined by temperature
and it may stop).
2. Please pay attention to the polarity while connecting. There are normally two types of wiring: NC (negative connection)
and PC (positive connection).
NC : welding holder connected to “-“and work piece to “+”;
PC: workpiece to “-“and welding holder to “+”.
Please choose the proper connection according to different workpiece and processing method. Unstable arc, spatter, and
electrode sticking could happen if improper wiring is selected. Please change the quick connect plug to change the polarity
in case of above abnormal situation.

3) Please connect earth clamp t welder’s “+” and torch connect to welder’s “-“before TIG operation( as
shown in Fig 11.2). No PC is permitted or else welding can not processed normally. Connect torch
control cable to according connector and choose the proper welding mode per workpiece material
and check if the Tungsten electrode is in match with panel’s Tungsten electrode parameters and
current parameters. When under AC welding mode, improper balance parameter may result in
abnormal welding operation.

4) If the distance between workpiece and welder is long and the secondary line (holder cable and
ground cable) are long, please choose cables with wide cross section so that to lower cable voltage
drop.
Please preset current according to electrode specification, and clamp the electrode well. Welding
can be started by short circuit arc ignition. Please refer to welding parameters in Table 4.2

3. Please connect earth clamp to welder’s “+” and torch connect to welder’s “-“before TIG operation( as shown in Fig 10.2).
No PC is permitted or else welding can not processed normally. Connect torch control cable to according connector and
choose the proper welding mode per workpiece material and check if the Tungsten electrode is in match with panel’s
Tungsten electrode parameters and current parameters. When under AC welding mode, improper balance parameter may
result in abnormal welding operation.
