GYS FIREMAN LCD Welding Mask - User Manual

1. Introduction and Overview

The GYS FIREMAN 9-13 TRUE COLOR optoelectronic welding helmet is designed to provide essential protection for the welder's face and eyes. It safeguards against harmful UV and infrared radiation, as well as welding projections. This fully automatic mask transitions from a clear state to a dark shade in a fraction of a second upon arc ignition, ensuring continuous protection. Equipped with a comfortable headband, it allows for hands-free operation during various welding tasks.

Key features include:

• 2 Light Sensors: For reliable arc detection.
• TIG Welding Compatibility: Suitable for TIG welding applications above 2 Amperes.
• Active Filter: Offers shade ranges from 5-9 and 9-13.
• Low Intensity Range: A dedicated 4-9 shade range for low amperage welding.
• 7 Dark Shades: Adjustable shades from 5 to 13 to suit various welding and cutting operations.
• TRUE COLOR Technology: Provides a clearer, more natural view of the welding area.

2. Safety Information

Always prioritize safety when performing welding operations. This welding mask is a crucial piece of Personal Protective Equipment (PPE) but must be used correctly and in conjunction with other safety measures.

• Eye and Face Protection: The mask protects against harmful ultraviolet (UV) and infrared (IR) radiation, sparks, and spatter.
• Inspection Before Use: Always inspect the mask, including the lens and headband, for any damage before each use. Do not use if damaged.
• Not for Laser Welding: This mask is not suitable for laser welding applications.
• Overhead Applications: For overhead welding, additional head and shoulder protection may be required.
• Ventilation: Ensure adequate ventilation in the welding area to avoid inhaling hazardous fumes.
• Temperature Range: Do not use the mask outside its specified operating temperature range.

3. Setup

3.1 Headband Adjustment

Proper adjustment of the headband is essential for comfort and stability during welding. The GYS FIREMAN mask features a Multi Premium headband for optimal fit.

1. Adjust Head Circumference: Use the knob at the back of the headband to tighten or loosen it until it fits snugly around your head.
2. Adjust Head Support: Modify the top straps to adjust the height and position of the mask on your head.
3. Adjust Tilt: Use the side knobs to set the tilt angle of the mask, ensuring the viewing area is optimally positioned for your work.

3.2 Initial Checks

Before first use, and after any screen replacement, ensure all protective films are removed from both the inner and outer guard screens. Failure to do so will impair visibility and mask performance.

4. Operating Instructions

4.1 Automatic Darkening Function

The GYS FIREMAN welding mask is fully automatic. When the arc is struck, the mask will instantly switch from its clear state (shade 3) to the selected dark shade. When the arc stops, it will return to the clear state after a short delay.

4.2 Shade Selection

The mask offers a versatile range of dark shades to accommodate different welding processes and amperages. Use the external knob to select the appropriate shade:

• Shade 9-13: Standard range for most welding applications.
• Shade 5-9: Suitable for gas welding, cutting, and lower amperage welding.
• Shade 4-9: Special range for very low intensity welding or grinding.

4.3 Grind Mode

The mask includes a grind mode, which deactivates the auto-darkening function, allowing the user to grind without the lens darkening. This mode typically uses a clear shade (e.g., shade 3) for grinding tasks. Refer to the mask's external controls for activating and deactivating grind mode.

4.4 TRUE COLOR Technology

The integrated TRUE COLOR technology provides a significantly clearer and more natural color perception of the welding arc and workpiece. This enhances visibility and reduces eye strain, allowing for more precise welding.

5. Maintenance

5.1 Screen Replacement

Regularly inspect and replace the inner and outer guard screens if they become scratched, pitted, or otherwise damaged to maintain optimal visibility and protection.

1. Outer Guard Screen Replacement: The outer guard screen can be removed by gently placing a finger under the screen at point A of the mask and prying it out.
2. Inner Guard Screen Replacement: To change the inner guard screen, slide it downwards, placing a finger on point B.
3. Protective Film: When installing a new screen, remember to remove any protective film beforehand. This film cannot be removed once the guard screen is in position.

5.2 Cleaning

• Lens Cleaning: Clean the auto-darkening filter and guard screens with a soft, clean cloth and a mild cleaning solution. Do not use abrasive cleaners or solvents.
• Helmet Body Cleaning: Wipe the helmet body with a damp cloth.
• Sensors: Keep the light sensors clean and unobstructed for proper operation.
