earth clamp with work piece.
2d. The electrode holder cable should normally be connected to the positive
terminal, while the work piece should be connected to the negative
terminal.
3. Power Supply Switch
In case that power switch is on, built-in fan start work and current meter
displays the current value.
4. Function Switch
Function switch enables the option among MMA, TIG and CUT according to
practical welding task requirement.
4a. TIG Welding Function
Connect with gas supply: Connect the argon hose to the copper nozzle of
the back panel. The gas supply system includes the gas bottle, air
regulator and gas hose. The connection of parts of gas system should be
firm to prevent the gas leakage.
Install the argon torch according to the drawing. Connect the copper
screw on the cutting torch to the output terminal of the one-knob of the
front panel, and fasten it toward clockwise direction to avoid gas leaking.
Connect the plug of the closed circuit to the "+" socket on the panel board;
Connect the earth clamp with the work piece.
4b .PLASMA Cutting Function
Connect the gas hose with the terminal "IN" of regulator and connect the
"OUT" terminals of regulator with the copper tub. The pressure and
volume of output gas should be sufficient.
Connect the copper nut of the cutting torch to the knob of the panel board;
plug with the plug of the panel board.
Connect the fast plug of earth cable with front panel of this welding &
cutting equipment.
4b .MMA Welding Function (CT-312)
There are two modes of connection according to the specification of
welding electrode.
•Straight polarity: electrode holder to "-", work piece to "+";
•Reverse polarity: electrode holder to "+", work piece to "-"
5. Welding Current Output Setting
According to practical demand, set the parameters of current output by the
operation of "ARC" "TIG", or "CUT"
INSTALLATION OF THE GAS REGULATOR:
1)
Seal the connection of the copper gas hose and the "IN" terminal and 'OUT"
terminals.
2)
Connect the regulator seal to the installation place of the regulator.
3)
Fix the rack with screw to the place of the air regulator at the back of the
machine.
4)
Remove the rubber nut. Connect the regulator with the track.
5)
Release the gas valve, modulate the pressure of gas to stipulated pressure,
and press the button.
6)
The gas pressure is 4 times of normal atmospheric pressure.
7)
In case that the water-filtering bottle is full with water, remove the water.
Please note that:
--Please choose the Argon gas supply respectively for TIG welding and
compressed air supply of higher than 4 bars for plasma cutting.
--The duty cycle for cutting of the machine is 60%.
