XR938H True Colour Light Reactive Welding and Grinding Helmet (ENGLISH)
DO AND DON'TS
Ensure the inside cover glass is fitted before use
and remove protective film.
Ensure that the cover glass is clean and there is
no dirt or spatter covering the two sensors at the
front of the filter.
Inspect all parts for signs of wear or damage.
Any scratched or cracked parts should be replaced
prior to use.
Never place the helmet on a hot surface
Never open or tamper with the filter cartridge.
OPERATION
1. ADJUST THE WELDING HELMET
ACCORDING TO INDIVIDUAL
REQUIREMENTS
The headband should be
adjusted both in diameter
and height.
The angle between face
and helmet should
be adjusted.
Recommended
angle: 10°-12°.
2. ON/OFF
The solar unit automatically switches on when
exposed to light created by welding.
3. SELECT THE SHADE NUMBER
The shade is infinitely adjustable between 5
and 13.
The shade number can be selected by turning
the shade knob on the side of the helmet.
The set shade is indicated by the arrow on the
knob.
4. SELECT DELAY TIME
The delay time can be set variably between MAX
(1.0 second) and MIN (0.1 second) using the delay
knob on the inside of the filter.
MAX – for most welding applications, especially
for high amperage welding.
MIN – typically used for tack welding and
spot welding.
Longer delay can also be used for TIG welding
in order to prevent the filter from returning to the
clear state when the sensor is briefly covered
by the hand, torch, etc. Long delay also protects
against glow from the weld pool after welding.
5. SELECT THE SENSITIVITY
The sensitivity can be adjusted by rotating the
knob on the inside of the helmet. This alters the
sensitivity of the helmet to ambient light levels.
On low sensitivity the filter will not switch due to
sunlight or welders working nearby.
On high sensitivity the helmet will respond better
to small arcs or TIG welding.
The set sensitivity is indicated by the arrow on
the knob.
6. SELECT GRIND MODE
To select grind mode rotate the shade knob
clockwise to the top position. Once the arrow has
gone past shade 13, a click indicates that the filter
is now set to grind mode.
PLEASE NOTE – Grind mode is intended for
grinding and not for welding. Before you restart
welding, please set the filter back to weld mode
and select the required shade for your application.
To do this, rotate the shade knob anti-clockwise.
