Notices:
• Check the condition of welding and connection units fi rstly, otherwise there will be malfunction
such as ignition spark, gas leakage, out of control and so on.
• Check that whether there is enough Argon gas in the shield gas cylinder, you can test the
electromagnetic gas valve through the switch on the front panel.
• Do not let the torch aim at your hand or else of your body. When you press the torch switch,
the arc is ignited with a high-frequency, high-voltage spark, and the ignition spark can cause
interferences in equipment.
• The fl ow rate is set according to the welding power used in the job. Turn the regulation screw
to adjust the gas fl ow which is shown on the gas hose pressure meter or the gas bottle pressure
meter.
• The spark ignition works better if you keep the 3 mm distance from the workpiece to the tung-
sten electrode during the ignition.
3-1. Duty Cycle Curve
Warning: Work in Overload is Harmful to the Welding Machine
The letter “X” stands for duty cycle, which is
de fi ned as the proportion of the time that a
machine can work continuously within a certain
time (10 minutes). The rated duty cycle means
the proportion of the time that a machine can
work continuously within 10 minutes when it
outputs the rated welding current.
The relation between the duty cycle “X” and
the output welding current “I” is shown as the
right fi gure.
If the welder is over-heat, the IGBT over-heat
protection unit inside it will output an instruction
to cut output welding current, and brighten
the over-heat pilot lamp on the front panel. At
this time, the machine should be relaxed for 15
minutes to cool the fan. When operating the
machine again, the welding output current or
the duty cycle should be reduced.
3-2. Operation in MMA mode
- Connect the output cables
- Turn on the welding machine to the power switch, the fan starts to work!
- Select the mode to switch to MMA.
- Set the desired welding current according to the welding task.
- Start the work.
3-3. Operation in TIG mode
- Connect the ground cable to the positive (+) pole!
- Use a TIG torch connected to the negative pole (-)!
- Set the machine in to TIG-2T or TIG-4T mode!
- Set the welding current.
- Adjust the gas post
fl ow and down slope time on the control panel.
- Keep the distance between tungsten and workpiece between 2 and 4 mm , press the gun
button , you will hear the voice of high-frequency ignition, after the arc penetrates through the
splash disappears and you can start the work.
