The overload indicator. It lights in the following two situations:

a) If the machine has malfunctioned and cannot be operated.
b) If the welding machine has exceeded the standard overload time, it enters safety mode and then switches off. This means that the machine, as part of its temperature and overheating control, enters rest mode. During this process, the warning light on the front panel illuminates. In this situation, it is not necessary to remove the power plug from the socket. The fan can continue to function to cool the unit. If the red light does not illuminate, this means that the appliance has cooled down to operating temperature and can be used again.

7. Connecting the wires

CAUTION! Connecting the cables to the device must be done with the power supply disconnected and the device turned off.

Checking the tightness of gas connections (LIFT Tig mode only)

Before first use and then at regular intervals, it is recommended to check for gas leaks. The procedure should be carried out as follows:

1) Connect the regulator and gas line assembly and tighten all connections and clamps.
2) Slowly open the cylinder valve.
3) Close the cylinder valve and watch the pressure gauge needle on the regulator. If the needle drops towards zero, it means there is a gas leak. Occasionally, the gas leakage can be slow. To identify it, leave the gas pressure in the regulator and the line for a long time (about 15 minutes).
4) In the event of a gas leak, check all connections and terminals for leaks. Brushing or spraying with soapy water will cause bubbles to appear at the location of the leak.
5) Tighten clamps or couplings to eliminate gas leakage.

IMPORTANT! - It is recommended to check for gas leakage before starting the machine. It is recommended to close the cylinder valve when the machine is not in use.

MMA welding mode:

1) Connect the welding cable to the connection marked with "+" and twist the cable plug to secure the connection.
2) Connect the ground wire to the connection marked with "-" and twist the wire connector to secure the connection.
3) Connect the power cord and turn on the power.
4) Connect the ground wire to the workpiece. Once these steps are completed, welding can begin.

CAUTION! Cable polarity may vary! All polarity information should be described on the package provided by the electrode manufacturer!

8. Operation of the device

8.1. Setting the LIFT TIG welding parameters

Connect the welding cables as described above. Switch on the welding machine and set the welding current suitable for the material to be welded. When the work is finished, switch off the welding machine and disconnect it from the power supply.

Polarity of TIG welding leads

Negative polarity is used in most TIG welding operations. The welding torch is connected to the negative pole and the grounding clamp to the positive pole. Thus, the wear of the electrode is reduced and the amount of heat stored in the welded material increases.

Arc ignition in the TIG LIFT method

To ignite the welding arc in the TIG LIFT method, unscrew the valve on the handle, press the button, then gently rub the tungsten electrode on the workpiece and slightly lift the torch so that the arc ignites. Releasing the button ends the welding process (in 2T mode).
