5. Instruccions de funcionament
5.1. Encendre/apagar
- To power on, flip the Power Switch on the rear panel to the 'ON' position. The digital display will illuminate.
- To power off, flip the Power Switch to the 'OFF' position.
5.2. Selecció de mode
Use the Modes Switch on the front panel to select your desired operation mode:
- TIG: For Gas Tungsten Arc Welding.
- MMA (ARC): For Shielded Metal Arc Welding.
- Neteja: For post-welding cleaning processes.
5.3. Ajust de corrent
Rotate the Current Knob on the front panel to adjust the welding current from 10A to 155A. The selected current will be shown on the Current Display.
5.4. 2T/4T Mode (TIG Welding)
The 2T/4T switch allows for different torch trigger functionalities:
- 2T (Spot Welding): Press and hold the torch trigger to weld; release to stop. Suitable for short welds, tack welding, and thin plate welding.

9. Consells d'usuari
- For beginners, start with lower current settings and practice on scrap metal to get a feel for the machine and different welding modes.
- Always ensure your workpiece is clean and free of rust, paint, or oil for the best welding results and to prevent contamination.
- When using TIG, maintain a consistent arc length and torch angle for smooth, uniform beads.
- The 4T mode is particularly useful for longer welds, as it allows you to release the trigger after initiating the arc, reducing hand strain.
