The ESAB Savage A40 welding helmet integrates several key components and features for enhanced performance and user comfort:

• Penapis Penggelapan Automatik (ADF): Provides automatic shade adjustment upon arc ignition.
• Teknologi Warna Sebenar: Offers a brighter view and enhanced color definition for improved visibility of the weld puddle and surrounding environment.
• External Shade Adjustment: Easily adjust the shade level between DIN 9 and DIN 13 without removing the helmet.
• Internal Sensitivity Control: Adaptable feature for fine-tuning the lens reaction to arc light, especially useful for low amperage TIG welding.
• Internal Delay Control: Adjusts how long the lens remains dark after the welding arc stops. A short delay is ideal for tack welding, while a longer delay is beneficial for high ampkimpalan erage.
• Four Arc Sensors: Ensures a higher and more reliable auto-darkening response.
• besar ViewKawasan: A 100 x 50 mm (3.93 x 1.96 in.) viewing area provides a wide field of vision and increased spatial awareness.
• Butang Kisar Luaran: Conveniently switch to Shade 4 Grind Mode without lifting the helmet.

2. Ensure the battery is correctly inserted with the correct polarity.
3. A low battery indicator may be present on the ADF. If illuminated, replace the battery.

5. Arahan Operasi

Familiarize yourself with the helmet's controls before beginning any welding task.

5.1 Hidupkan/Mati Kuasa

The auto-darkening filter is typically solar-powered with battery assist and activates automatically when exposed to light. There is no manual on/off switch for the ADF itself. The helmet will enter a low-power state when not in use.

5.2 Shade Adjustment

The external knob on the side of the helmet allows for quick adjustment of the welding shade.

• Rotate the external knob to select a shade level between DIN 9 and DIN 13.
• Choose the appropriate shade based on your welding process and amperage. Refer to standard welding shade charts for guidance.

5.3 Kawalan Sensitiviti

The sensitivity control, located inside the helmet, adjusts how readily the ADF reacts to the welding arc.

• Adjust the sensitivity knob (labeled "SENSITIVITY") to a higher setting for welding low amperage TIG or in environments with low ambient light.
• Lower the sensitivity in bright environments or when experiencing unwanted darkening from other light sources.

5.4 Delay Control

The delay control, also located inside the helmet, determines how long the lens remains dark after the welding arc ceases.

• Set a short delay for quick tack welding to speed up work.
• Set a longer delay untuk tinggi amperage welding to protect your eyes from residual glow of the weld puddle.

5.5 Grind Mode

The external grind button allows for easy switching to grind mode without removing the helmet.

• Press the external "Grind" button to activate Shade 4 Grind Mode. The lens will remain in a light shade suitable for grinding operations.
• Press the button again to return to welding mode.
