7- Quick water outlet connector(blue): circulation water outlet,connect with welding torch wather inlet hose.
8- Water tank: welding torch cooling circulation tank,consist of water pump,radiator,fan,water circulation system,water storage tank and other components.
9- Digital display, shows parameters and real-time output current value.
10- Error indicator light:When the machine functions normally, this light is always off. It will lit(yellow)when abnormal conditions occur.
11- AC/DC switch: switch between AC mode/DC mode.
12- Pulse/No pulse switch: press the ''Pulse'' side, it will be pulsed welding process; and press ''No pulse'' side, constant current welding.
13- Remote control/Close control switch: press''Remote'' side, the machine is controlled by remoted control box or foot pedal switch; press''Close'' side, panel potentiometer adjustment and control.
14- AC380V power indicator light: this light is always on when the machine functions well.
15- Gas detection switch: press ''Gas detection'' and the gas is directly vented, to check whether the gas circuit works normally;press''Welding ''and the gas comes out from the torch.
16- End Amps adjust knob: rotate it to adjust the arc ending current, which means the welding current at which welding is to be stopped; in general, end amps is for filling arc crater.
17- Pulse Amps adjust knob: rotate it to adjust the pulsed ending current: In pulsed welding process, the peak current and base current are formed by welding current adjustment.
18- Welding Amps adjust knob:rotate it to adjust the welding ending current; in no pulse mode, it is welding current adjustment, while in pulse mode,the peak current and base current are formed by pulse current adjust ment.
19- Start Amps adjust knob: rotate it to adjust the arc starting current;which means the welding current at when press torch trigger and turn on the power source,to preheat the work piece in the welding process.
20- Clearance Effect adjust knob: In AC TIG welding, it is used to adjust AC positive and negative half-wave width ratio and use AC negative half-wave to clean the surface oxide film of the work piece. Generally , it is placed in the middle of the scale, if the ball formed in the end of tungsten electrode is not in good condition or the welding brightness of 1 or 2. The potentiometer does not work in MMA or DC TIG welding.
21- Pulse Frequency adjust knob: rotate to adjust pulse frequency,which refers to ,per unit time,number of pulse period change per second.
22- Pulse Width adjust knob: rotate to adjust the pulse width, which is, per unit time,the ratio of the peak current per second during the pulse period.When the pulse width is larger,the welding spot of the welding seam is larger, and vice versa.
23- Post Flow adjust knob: rotate to adjust post flow time,which means the time of continuous air supply after the welding stops and the nozzle of the welding torch should keep to be pointed at the welding seam, to cool the work piece and ensure the welding quality.
24- 2T/4T switch: switch between 2T/4T welding mode.
25- Up Slope adjust knob: rotate to adjust up slope time, which indicated the time from arc starting current to welding current.
26- AC Frequency adjust knob: rotate to adjust AC frequency.When in DC TIG welding, the potentiometer does not work. Low AC frequency is suitable for large current, and wide welding seam requirement; When AC frequency is high, the melting speed and strength are obviously strengthened,which is suitable for thin plate, and narrow welding bead.
27- Down Slope adjust knob: rotate to adjust down slope time, which refers to the time from the normal welding current to arc ending current
28- TIG/MMA switch: switch between TIG/MMA welding process.
Brief instruction for welding operation:
1.Wear necessary and qualified protective equipment,such as helmet,face shield,goggles,earplugs,protective clothing, gloves, insulating shoes,etc.
2.Check and confirm that the power supply to be connected to the welding machine is consistent with the power supply allowed.
3.Check and confirm that the insulation layer of all wires and cables of the welding machine is not damaged,the welding cable and the grounding cable are connect to the welding machine correctly.
4.Check and confrmthat the ventilation around the welding machine is freely vented, and no sundries stacking on the machine.
5.Make sure that the vent of welding machine is not covered and blocked to prevent failure of cooling system.
6.Connect the shielding gas source.The gas supply channel shall include gas cylinders, argon gas pressure reducing valve and air hose.The connection part of the hose should be tightened with a hose clamp or other articles to prevent leakage and prevent air from getting in.
7.Connect the welding torch cable connector to the nagative pole of welding cable coupling socket on the front panel and tighten them clock wire. The aviation plug, air nozzle plug and water nozzle plug on the welding toch are connected to the corresponding interface of the welding machine panel respectively, and tighten the screws.
8.Connect the quick connector of the work piece cable to the positive pole of welding cable couping socket on the front panel and tighten them clockwise.The earth clamp on the other end, clamps the work piece.
9.Connect the power cord to the distribution box with corresponding input voltage level according to the welding machine; do not connect the wrong voltage, and ensure that the error of the power supply voltage is within the allowable range.
10. Turn on the machine with pressing the power switch, work LED is lit,and fan works.
11. Set parameters on the control panel according to the requirment and start welding operation.
12. Carry out the welding operation according to the normal procedure .During the welding process,the welding parameters can be modified according to the actual situation.
13. After weding operation, turn off the machine power switch and turn off the switch of the distribution box.
