Welding Helmet

BEFORE WELDING
**Read and understand all instructions before using.
Auto Darkening Welding Helmets are designed to protect the eye and face from sparks, spatter, and harmful radiation under normal welding conditions.
This product comes ready for use, but before welding; check the front cover lens to make sure that they are clean, and there’s no dirt is covering the two sensors on the front of filter cartridge. Also check the front/inside cover lens and the front lens retaining frame to make sure that they are secure. Check all operating parts before using to ensure there is no sign of damaged or wear parts.
Any scratched, cracked or pitted parts should be replaced immediately before using again to avoid severe personal injury. Check light tightness before using each time.
Select the shade number you required by turning the shade knob. (Seeing the Shade Guide Table).
Adjust headband so that the helmet is seated as low as possible on your head and close to your face. Adjust helmet’s angle when in the lowered position by turning the tilt adjustment.
WARNING** Make sure to remove any additional protection foil from both sides of Protection Lens.

OPERATING INSTRUCTIONS

3.1 Adjusting the fit of the helmet

• The overall circumference of the headband can be made larger or smaller by rotating the knob on the back of the headgear. (See adjustment “Y” in Fig. 2), which can be done while wearing helmet to keep the helmet firmly on the head with the right tension.
• If the headgear is riding too high or too low on your head, adjust the strap which passes over the top of your head. To do this release the end of the band by pushing the locking pin out of the hole in the band. Slide the two portions of the band to a greater or lesser width as required and push the locking pin through the nearest hole. (See adjustment ” W” in Fig. 2)
• Test the fit of the headband by lifting the helmet up and closing down a few times while wearing it. If the headgear moves while tilting, re- adjust it until it is stable.

3.2 Adjusting The Distance Between The Helmet And The Face.

• Step1: Loosen the block nut (See “T” in Fig. 2) to adjust the distance between the helmet and your face in the down position.
• Step2: Loosen the block nut on either side of the helmet and slide it nearer or further from your face. (See adjustment “Z” in Fig. 2). It is important that your eyes are the same distance from the lens. Otherwise the darkening effect may appear uneven.
• Step3: Re-tighten the block nut when adjustment is complete.

WELDING FILTER OPERATION/FEATURES
4.1 Selecting the Operating Mode
Use the switch button on the back of shade cartridge to select the mode appropriate for the work activity. (see the technical specification of your helmet).
Grind mode – can be selected by rotating the shade control knob till an audible click is heard (Fig. 3) Grind mode-used for metal grinding applications. In this mode the shade function is turned off. The shade is fixed at shade DIN 3.5 that allows a clear view to grind while the helmet providing face protection.
“Grind Mode Is Intended For Grinding Only Not For  Welding.”
Weld mode – Used for most welding applications. In this mode the shade functions is turned on when it optically senses a welding arc. Select shade level, delay time and sensitivity as required.
4.2 Selecting Shade Level
Select the shade level  you require according to the welding process you will use by referring to the “Shade Selection Chart” below for settings. Turn the shade control dial on the lens to the shade number require. (see Fig.3).
4.3 Selecting Delay Time
When welding ceases, the viewing window automatically changes from dark back to light but with a pre-set delay to compensate for any bright afterglow on the workpiece. The delay time\response can be set to “MIN” short: 0.1 sec.) or “MAX” (long:1.0sec.), as you require by using the infinitely dial knob on the back of the shade cartridge. (see Fig.7)
It is recommended to use a shorter delay with spot welding applications and a longer delay with applications using higher currents. Longer delays can also be used for low current TIG welding in order to avoid the filter opening when the light path to the sensors is temporarily obstructed by a hand, torch, etc.
4.4 Sensitivity
The sensitivity can be set to “Hi”(high) or “Lo”(low) by using the infinitely dial knob on the back of the shade cartridge. The “Min-Max” setting is the normal setting for everyday use. The maximum sensitivity level is appropriate for low welding current work, TIG, or special applications. While the operation of the helmet is disturbed by excess ambient light, or another welding machine close by, use the “low” setting. (see Fig.8) As a simple rule for optimum performance, it is recommended to set sensitivity to the maximum at the beginning and then gradually reduce it, until the filter reacts only to the welding light flash and without annoying spurious triggering due to ambient light conditions (direct sun, intensive artificial light, neighboring welder’s arcs, etc).

MAINTENANCE

5.1 Replacing Front Cover Lens:
For model, see “TECHNICAL SPECIFICATIONS” Model 1: (fig 12)
To replace the front cover lens, place your fingernail in recess below the mask and flex lens upwards until it releases from edges.
