4. Setup

4.1. Welder Setup (HBT250P)

1. Placement: Place the welder on a stable, level surface with adequate ventilation. Ensure clear space around the machine for airflow.
2. Power Connection: Connect the welder to a suitable power supply according to the specifications. Ensure the power outlet is properly grounded.
3. Gas Connection: 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.
4. TIG Torch Connection: Connect the TIG torch to the appropriate port on the front panel. Ensure the gas line and power cable are securely attached.
5. Ground Clamp Connection: Connect the ground clamp cable to the ground terminal on the welder. Attach the ground clamp securely to the workpiece or welding table, ensuring good electrical contact.
6. Electrode Installation: Insert the appropriate tungsten electrode into the TIG torch collet and tighten.

4.2. Welding Helmet Setup (HT-111)

1. 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.
2. Lens Protection Film: Remove any protective films from the inside and outside of the auto-darkening lens.
3. Function Test: 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. Operating Instructions

5.1. Welder Operation (HBT250P)

1. Power On: Turn on the main power switch on the welder. The digital display will illuminate.
2. Select Welding Mode: Use the mode selection buttons to choose between MMA (Stick) or TIG welding.
3. Select Current Type (TIG): For TIG welding, select AC for aluminum or DC for steel, stainless steel, and other metals.
4. Adjust Parameters: Use the mechanical gear knob and corresponding buttons to set welding parameters such as:
   • Amperage: 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: Control the ramp-up and ramp-down of current at the start and end of the weld.
   • 2T/4T Mode:
     • 2T (Two-Touch): Press and hold the torch trigger to start the arc; release to stop.
     • 4T (Four-Touch): Press and release to start; press and release again to stop. Useful for long welds.
5. Gas Flow: Open the gas cylinder valve and adjust the regulator to the recommended gas flow rate for your welding application.
6. Begin Welding: 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)

1. Shade Adjustment: 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.
2. Sensitivity Adjustment: 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.
3. Delay Time Adjustment: 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.
4. Grind Mode: 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.
