2. Conecta a terra clamp cable ao terminal negativo (-) do panel frontal.
3. Fixar firmemente o conector de terraamp á peza de traballo ou á mesa de soldadura.
4. Introduza o eléctrodo de soldadura desexado no portaelectrodos.
5. Turn on the machine using the power switch on the rear panel.
6. Select the "MMA" welding mode on the control panel.
7. Adjust the welding current using the adjustment knob according to the electrode type and material thickness.

5.2. TIG Welding Setup

1. Connect the TIG torch cable to the negative (-) terminal on the front panel.
2. Conecta a terra clamp cable ao terminal positivo (+) do panel frontal.
3. Fixar firmemente o conector de terraamp á peza de traballo ou á mesa de soldadura.
4. Connect the gas hose from your inert gas cylinder (e.g., Argon) to the gas inlet on the rear panel of the machine (Figure 3). Ensure the gas cylinder is equipped with a pressure regulator and flow meter.
5. Install the tungsten electrode and ceramic nozzle onto the TIG torch.

8. Adjust gas flow rate, welding current, and other TIG parameters (AC/DC, Pulse, 2T/4T) as required for your material and application.

6. Modos e funcións de funcionamento

The HBT250P offers multiple welding modes and adjustable parameters for various welding tasks.

6.1. Welding Mode Selection

Figure 5: Detailed Control Panel Functions for Mode Selection.

• MMA (ARC) Welding Mode: For stick electrode welding. Suitable for carbon steel, stainless steel, and cast iron. Welding wire diameter: 2.5/3.2/4.0 mm. Welding thickness: 2-12 mm.
• TIG Welding Mode: For Gas Tungsten Arc Welding. Offers precise control and high-quality welds.
  • TIG de CA: Ideal for welding aluminum and its alloys.
  • TIG CC: Suitable for stainless steel, carbon steel, copper, titanium, and other non-ferrous metals.
  • Pulse TIG: Provides better control over heat input, reducing distortion and improving weld quality, especially on thin materials.
  Welding wire diameter for TIG: 1.6/2.4/3.2 mm. Welding thickness for TIG: 1.2-4 mm.

6.2. Función 2T/4T

• 2T (Manual Mode): Press and hold the torch trigger to weld; release to stop. Ideal for short welds.
• 4T (Semi-automatic Mode): Press and release the trigger to start welding; press and release again to stop. Convenient for longer welds, reducing hand fatigue.

6.3. Axuste de parámetros

The adjustment knob and parameter knob allow fine-tuning of various settings:

• Ampera: Controls the welding current (10-200A for TIG, 20-120A for MMA).
• Control de tempo: For pre-flow, post-flow gas, up-slope, and down-slope times in TIG welding.
• Frecuencia: Adjusts the AC frequency for aluminum welding.
• Ciclo de traballo: Controls the balance between peak and base current in pulse welding.
• Balance de CA: Adjusts the cleaning action and penetration when welding aluminum in AC TIG mode.

The machine offers continuous adjustment for these parameters, allowing for precise control over the welding process.

7. Mantemento

Un mantemento regular garante a lonxevidade e o funcionamento seguro da súa máquina de soldar.

• Limpeza: Regularly clean the machine's exterior with a dry, soft cloth. Use compressed air to blow out dust from the cooling vents. Do not use solvents.
• Inspección de cables: Periodically check all welding cables, connections, and the power cord for damage, fraying, or loose connections. Replace damaged parts immediately.
• Tocha e Clamp Mantemento: Inspect the TIG torch and electrode holder for wear and tear. Clean or replace consumables (tungsten electrodes, nozzles, collets) as needed. Ensure the earth clamp fai un bo contacto coa peza de traballo.
• Almacenamento: Store the welding machine in a dry, clean, and well-ventilated area, away from direct sunlight, moisture, and corrosive substances.
• Inspección interna: For internal cleaning or inspection, it is recommended to consult a qualified technician.

9. Consellos de usuario

• Control de pedal: For enhanced control over welding current, consider using an optional foot pedal. This allows for hands-free current adjustment during TIG welding.
• Tungsten Electrodes: Always use the correct type and size of tungsten electrode for your material and welding process. Ensure the tungsten is properly ground for optimal arc stability.
• Configuración do pulso: Experiment with pulse frequency and duty cycle settings to find the ideal parameters for thin materials or when minimizing heat input is crucial.
• Soldadura de aluminio: When welding aluminum with AC TIG, pay attention to the AC balance setting. A higher cleaning action (more positive half-cycle) helps break up aluminum oxide, while more penetration (more negative half-cycle) increases weld depth.
• Recambios: Keep a small stock of common consumables like tungsten electrodes, ceramic nozzles, and collets to avoid interruptions during welding projects.
