5. Configuración

Before operating the welder, ensure all connections are secure and correct.

5.1 Máquina superadaview

Figura 5.1: Front and rear panel layout with key components.

• Interruptor de encendido / apagado: Located on the rear panel.
• Fan: Cooling fan located on the rear panel. Ensure it is not obstructed.
• Gas In: Gas inlet connection on the rear panel for inert gas supply (e.g., Argon for TIG).
• Botón de axuste de corrente: Main control for welding current.
• Pulse ON/OFF Shift Switch: Activates or deactivates the pulse welding function.
• Cl Claseamp Conexión: Conecte a terra clamp cable to the appropriate terminal for your welding process.
• Welding Torch/Electrode Holder Connection: Connect the TIG torch or MMA electrode holder to the corresponding terminal for your welding process.

5.2 Conexión de alimentación

1. Asegúrese de que o interruptor de alimentación da soldadora estea na posición de apagado.
2. Connect the power cord to a suitable 110V or 220V AC power outlet. The machine automatically detects the input voltage. Ensure the outlet is properly grounded and can supply the required ampera.

5.3 Conexión de gas (para soldadura TIG)

1. Connect one end of the gas hose to the "Gas In" port on the rear of the welder.
2. Connect the other end of the gas hose to your inert gas cylinder (e.g., Argon) via a pressure regulator.
3. Asegúrate de que todas as conexións estean ben axustadas para evitar fugas de gas.

5.4 Conexións de cables de soldadura

1. Cl Claseamp: Conecte a terra clamp cable to the negative (-) terminal for DC TIG/MMA or to the appropriate terminal as indicated for AC TIG. Secure the ground clamp á peza de traballo ou á mesa de soldadura, garantindo un bo contacto eléctrico.
2. Soplete TIG: For TIG welding, connect the TIG torch cable to the positive (+) terminal for DC TIG or to the appropriate terminal for AC TIG. Connect the gas line from the torch to the welder's gas output.
3. Soporte de eléctrodos: For MMA (Stick) welding, connect the electrode holder cable to the positive (+) terminal.

6. Instrucións de funcionamento

6.1 Funcionamento xeral

1. After completing all connections, turn on the power switch on the rear panel.
2. Select the desired welding process (TIG or MMA) and current type (AC or DC) using the front panel controls.
3. Adjust the welding current using the "Current Adjust Knob" according to the material thickness and electrode/filler rod size.
4. For TIG welding, set the gas flow rate on your regulator.

6.2 TIG Welding (AC/DC)

The HVT250P supports both AC TIG for aluminum and DC TIG for other metals.

Figura 6.1: Demonstrating AC/DC TIG welding. Welding wire diameter: 2.4/3.2mm, Welding thickness: 1-8mm.

• TIG de CA: Select AC mode for welding aluminum and magnesium alloys. This mode provides a cleaning action that breaks up oxides on the material surface.
• TIG CC: Select DC mode for welding stainless steel, carbon steel, copper, and other non-ferrous metals (except aluminum).
• Pulse TIG: Engage the "Pulse ON/OFF Shift Switch" to activate pulse mode. Adjust pulse frequency (20-200Hz) and duty cycle (10-90%) as needed for better heat control and reduced distortion, especially on thin materials.
• Ensure a tungsten electrode of appropriate size and type is installed in the TIG torch.
• Maintain proper arc length and torch angle for optimal weld quality.

6.3 Soldadura con electrodo electromagnético (MMA)

The HVT250P also functions as an MMA (Manual Metal Arc) or Stick welder.

Figura 6.3: A welder performing MMA welding. MMA welding wire diameter: 2.5/3.2mm, Welding thickness: 2-12mm.

• Conecte o portaelectrodos ao terminal positivo (+) e á toma de terra.amp ao terminal negativo (-).
• Insert the appropriate coated electrode into the electrode holder.
• Select MMA mode on the control panel.
• Adjust the welding current based on the electrode type and diameter, and the material thickness.
• Strike the arc by lightly touching the electrode to the workpiece and quickly lifting it slightly to establish the arc.

7. Mantemento

Regular maintenance ensures the longevity and safe operation of your welding machine. Always disconnect power before performing any maintenance.

• Limpeza: Periodically clean the interior of the machine using dry compressed air to remove dust and metal particles. Ensure the cooling fan and vents are free from obstructions.
• Inspección de cables: Regularly inspect welding cables, ground clamp, and torch for damage, cuts, or loose connections. Replace damaged components immediately.
• Tungsten Electrodes (TIG): Sharpen or replace tungsten electrodes as needed to maintain arc stability and weld quality.
• Gas System: Check gas hoses and connections for leaks.
