1. Introduction
This manual provides essential information for the safe and effective use of your DEKO MZ236 Auto-Darkening Solar Powered Welding Helmet. Please read these instructions carefully before operation and retain them for future reference. This helmet is designed to protect your eyes and face from sparks, spatter, and harmful radiation under normal welding conditions.
Safety Precautions
- Always wear appropriate personal protective equipment (PPE) in addition to the welding helmet.
- Ensure the helmet is correctly adjusted and functioning before each use.
- Do not use the helmet if any part is damaged or appears to be malfunctioning.
- This helmet is not suitable for laser welding or overhead welding applications.
- Protect the lens from scratches and impacts.
2. Components Overview
Familiarize yourself with the main parts of your welding helmet:

- Solar Battery Panel: Converts light energy to electrical energy to charge the auto-darkening filter (ADF).
- Arc Sensor: Detects the welding arc and sends a signal to instantly darken the ADF.
- Auto-Darkening Screen (ADF): Protects eyes and face from sparks, spatter, and harmful radiation. Adjustable shade level 9-13.
- Headgear Adjustment Knob: Used to adjust the tightness of the headgear for a secure fit.
- Dark Shade Button: Adjusts the external light sensitivity.
3. Setup and Adjustment
Proper adjustment of the headgear is crucial for comfort and safety.
3.1 Headgear Adjustment

- Adjustable Front Joint: Position the helmet correctly on your head.
- Adjustable Top Strap: Adjust the strap over the top of your head to ensure the helmet sits at the correct height.
- Width Adjustment Knob: Rotate the knob at the back of the headgear to tighten or loosen the fit around your head.
- Angle Adjustment Knob: Adjust the angle of the helmet relative to your face for optimal viewing and protection.
- Soft Sweatband: Ensure the sweatband is comfortably positioned against your forehead to absorb perspiration.

4. Operating Instructions
The DEKO MZ236 helmet features an automatic darkening filter for seamless operation during welding tasks.
4.1 Auto-Darkening Function
Image 4.1: A three-step diagram illustrating the auto-darkening process: Step 1: High sensitivity detector sends a signal when the arc light enters. Step 2: Dimming screen darkens automatically according to the intensity of the arc light. Step 3: Dimming screen lightens up and returns to normal view after the arc light stops.
The helmet's ADF automatically switches from light to dark in 1/25000 seconds when an arc is detected, providing continuous protection. In case of power failure, the welder remains protected against UV and IR radiation to shade 16.
4.2 Adjustable Settings
Image 4.2: Close-up of the auto-darkening filter (ADF) showing controls for adjusting ARC sensor sensitivity (between low and high) and the darkening delay time (0.1s to 1.0s).
- Sensitivity Adjustment: Adjust the ARC sensor sensitivity between low and high to adapt to different ambient light conditions and welding processes.
- Delay Adjustment: Set the time it takes for the screen to return from dark to light (0.1s to 1.0s). This helps prevent eye fatigue when welding in pulsed modes or with short arcs.
4.3 Supported Welding Processes

5. Maintenance
Regular maintenance ensures the longevity and proper functioning of your welding helmet.
5.1 Cleaning
- Clean the helmet shell with a mild soap and water solution. Avoid harsh solvents.
- Wipe the auto-darkening filter (ADF) and cover lenses with a soft, clean cloth. Do not use abrasive materials or cleaners that could scratch the surface.
- Ensure all parts are dry before storage or next use.
5.2 Battery
The helmet is powered by a lithium battery (CR2032) with solar assistance, providing an extended lifespan of up to 5000 hours. The solar panel continuously charges the internal battery during use in bright light conditions. If the helmet fails to darken, check the battery. Replace the CR2032 battery if necessary, following the instructions for accessing the battery compartment, typically located on the ADF unit.
5.3 Storage
Store the helmet in a clean, dry place away from direct sunlight and extreme temperatures. Protect the lens from dust and scratches.
6. Troubleshooting
Refer to the following table for common issues and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Helmet does not darken when welding. | Low battery; Arc sensors blocked or dirty; Sensitivity set too low; Incorrect welding process selected. | Replace battery; Clean arc sensors; Increase sensitivity setting; Ensure helmet is suitable for the welding process. |
| Poor visibility through the lens. | Cover lens dirty or scratched; ADF unit dirty or damaged. | Clean or replace cover lens; Clean or replace ADF unit. |
| Helmet darkens intermittently or flashes. | Arc sensors partially blocked; Sensitivity too high for ambient light; Other light sources interfering. | Clear arc sensors; Adjust sensitivity; Shield from other bright lights. |
| Headgear is uncomfortable or loose. | Incorrectly adjusted headgear. | Re-adjust all headgear straps and knobs for a snug, comfortable fit. |
