INSTRUCTIONS FOR USE
3. Delay time
The amount of time required by the helmet to switch back from full dark to full light.
3.1 If the minimum value is selected, the delay time will be set to 0.1-0.25s, suitable for spot welding,
short welding or seam welding.
3.2 If the maximum value is selected, the delay time will be set to 0.85-1.0s, suitable for high current
welding or preventing eye fatigue from electric arcs or close viewing of incandescent pieces.
3.3 The medium value is suitable for most welding operations.
4. Sensitivity
According to the welding process and the ambient light, adjusting the "SENSITIVITY" knob will allow the
minimum amount of light - applied to the front sensors - needed to darken the LCD fi lter to be selected.
4.1 Select Min. for high current welding in a bright welding environment or in an environment with other
sources of interference.
4.2 Select Max. for low current welding or in a low light environment in welding, especially low current
argon arc welding.
4.3 Mid-range selection, suitable for most indoor and outdoor welding operations.
5. Welding / grinding feature
While cutting or grinding, the knob should be turned into the "Grind" position.
6. Test
6.1. Set the shading number to a value ranging from 9 to 13; press the TEST button; check whether the
LCD changes from light to dark, and then automatically returns to the bright state.
7. Adjusting the hood
7.1 The headband size can be adjusted manually. Press the rotary gear moderately and adjust tightness
to provide maximum comfort. The rotating gear is fi tted with a self-locking mechanism. Do not rotate
the gear before unlocking the clamp, to avoid damaging the adjustment mechanism.
7.2 The sides of the helmet accommodate positioning holes; adjusting the fi xed plate into the lateral holes
allows the viewing angle to be changed.
7.3 Adjusting screw tightness allows the face mask angle to be changed, and the face mask can be
turned up or down. The ideal welding angle is eyes and joints connected by a straight line perpendi-
cular to the fi lter.
8. Battery replacement
8.1 The auto-darkening welding helmet runs with 2 3V lithium batteries.
Note: Waste batteries should be disposed of in compliance with local laws, and the fi lters should be
disposed of in accordance with electronic waste material processing procedures.
8.2 The battery can be used continuously for 5,000 hours under normal conditions. The battery should be
replaced when the low voltage lamp is on.
Maintenance
1 To clean the fi lter, use tissues, lens paper or clean soft cotton with neutral detergent.
