4. Configuració
4.1. Welder Setup (HBT250P)
- Col·locació: Place the welder on a stable, level surface with adequate ventilation. Ensure clear space around the machine for airflow.
- Connexió d'alimentació: Connect the welder to a suitable power supply according to the specifications. Ensure the power outlet is properly grounded.
- Connexió de gas: Connect your inert gas cylinder (e.g., Argon for TIG welding) to the gas inlet on the welder using a gas hose and regulator. Ensure all connections are tight to prevent leaks.
- Connexió de la torxa TIG: Connect the TIG torch to the appropriate port on the front panel. Ensure the gas line and power cable are securely attached.
- Terra Clamp Connexió: Connecteu la terra clamp cable to the ground terminal on the welder. Attach the ground clamp fixat de manera segura a la peça o a la taula de soldadura, garantint un bon contacte elèctric.
- Instal·lació d'elèctrodes: Introduïu l'elèctrode de tungstè adequat a la pinça de la torxa TIG i estrenyeu-lo.
4.2. Welding Helmet Setup (HT-111)
- Headgear Adjustment: Adjust the headgear straps to ensure a comfortable and secure fit. The helmet should sit firmly on your head without being too tight or loose.
- Lens Protection Film: Remove any protective films from the inside and outside of the auto-darkening lens.
- Prova de funció: Press the 'TEST' button on the lens cartridge to verify the auto-darkening function. The lens should momentarily darken and then return to its clear state. If it does not, check the battery or expose the solar cells to light.
5. Instruccions de funcionament
5.1. Welder Operation (HBT250P)
- Encès: Turn on the main power switch on the welder. The digital display will illuminate.
- Seleccioneu el mode de soldadura: Use the mode selection buttons to choose between MMA (Stick) or TIG welding.
- Select Current Type (TIG): For TIG welding, select AC for aluminum or DC for steel, stainless steel, and other metals.
- Ajusta els paràmetres: Use the mechanical gear knob and corresponding buttons to set welding parameters such as:
- Ampera: Set the desired welding current based on material thickness and type.
- Pulse (Optional): If using pulse, adjust Peak Amps, Base Amps, Pulse Frequency, and Pulse Duty Cycle. Pulse helps control heat input and improve bead appearance.
- AC Frequency (AC TIG): Adjust for arc cone width and penetration. Higher frequency narrows the arc.
- AC Balance (AC TIG): Adjust for cleaning action on aluminum. Higher balance provides more cleaning.
- Up Slope/Down Slope: Controla la ramp-amunt i ramp-down of current at the start and end of the weld.
- 2T/4T Mode:
- 2T (Dos tocs): Press and hold the torch trigger to start the arc; release to stop.
- 4T (Quatre tocs): Press and release to start; press and release again to stop. Useful for long welds.
- Flux de gas: Open the gas cylinder valve and adjust the regulator to the recommended gas flow rate for your welding application.
- Començar la soldadura: With all safety precautions in place and helmet on, initiate the arc according to your selected mode and torch trigger setting.

5.2. Welding Helmet Operation (HT-111)
- Ajust de l'ombra: Rotate the external shade control knob to select the appropriate shade level (DIN 4/9-13) for your welding process. Refer to welding safety standards for recommended shades.
- Ajust de sensibilitat: Use the internal sensitivity dial to adjust how sensitive the lens is to the welding arc. Higher sensitivity means it will darken with less light.
- Ajust del temps de retard: Use the internal delay time dial to set how long the lens remains dark after the arc extinguishes. A longer delay is useful for high amperage welding or tack welding to prevent eye fatigue.
- Mode de mòlta: Some helmets have a 'Grind' mode (often a fixed shade 4). If available, switch to this mode for grinding operations to prevent the lens from darkening. Ensure you switch back to a welding shade before striking an arc.
