XR936H Large View Light Reactive
Welding and Grinding Helmet

WARNING

Please read and understand all instructions prior to using the Parweld
XR936H Large View Light Reactive Welding and Grinding Helmet.

GENERAL INFORMATION

This Parweld XR936H Large View Light Reactive Welding and Grinding Helmet will
not protect against severe impact hazards such as explosive devices or corrosive
liquids. Machine guards or eye splash protection must be used where these hazards
are present.

All Parweld light reactive welding filters are for use in arc welding or cutting appli­cations. This unit is suitable for all arc processes such as MIG, MAG, TIG, SMAW,
Plasma Arc and Carbon Arc.

Use this helmet only for face and eye protection against harmful rays, sparks and
spatter from welding, grinding and cutting.

The Parweld XR936H is not suitable for “overhead” welding appli­cations, laser welding, laser cutting applications, gas welding or
cutting.

In the event of electronic failure, the welder remains protected against UV and IR
Radiation according to Shade 16.

In order to maintain impact protection the Parweld light reactive welding filter should
always be used with original Parweld inner and outer cover lenses.

The manufacturer is not responsible for any modifications to the welding filter or the
use of the filter in any other manufacturer’s helmet.

Protection can be seriously impaired if unapproved modifications are made.

DO

Ensure the front cover lens is fitted before use and remove protective film.

Ensure that the lens is clean and there is no dirt or spatter covering the two sensors
at the front of the cartridge.

Inspect all parts for signs of wear or damage. Any scratched or cracked parts should
be replaced prior to use.

DON’T

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 and is
recommended to be 10° - 12°.

2. ON/OFF

The filter unit is automatically switches on when
exposed to light.

Please dispose of packaging for the product in a responsible manner.
It is suitable for recycling. Help to protect the environment. Take the
packaging to the local amenity tip and place into the appropriate
recycling bin.

Never dispose of electrical equipment or batteries in with your domestic
waste. If your supplier offers disposal facility please use it or alternatively
use your local amenity tip and dispose in the correct manner. This will
allow the recycling of raw materials and help protect the environment.

10˚-12˚

3. SELECT THE SHADE NUMBER

The shade is infinitely adjustable between shades 5 and 13.
The shade number can be selected by sliding the linear switch (left 9-13 right 5-8) on
the inside of the helmet and 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 using the delay knob on the inside of the filter (the side
you look through) it can be set variably between MAX of 1.0 second or MIN of 0.1
second.

MAX – Longer delay is for most welding applications. Especially for high amperage

applications.

MIN – Shorter delay can be used for applications such as tacking, spot welding.

Longer delay can also be used for TIG welding in order to prevent the filter returning
to the clear state when the sensor is briefly covered by the hand, torch, etc. Long
delay also protects against weld afterglow.

5. SELECT THE SENSITIVITY

The sensitivity can be adjusted by rotating the knob on side 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 other welders working nearby. On high sensitivity the
helmet will respond better to small arcs or TIG welding.

The set sensitivity is indicated by the by the arrow on the knob.

6. SELECT GRINDING MODE

To select the grinding mode rotate the shade knob clockwise to the top position.
Once the arrow has gone past shade 13 a click should be felt, meaning the filter is
now set to grind mode.

Please note: Grind mode is intended for grinding and not for welding. Before you
restart welding ensure that the filter is set back to weld mode and select the required
shade for your application by rotating the shade knob anti-clockwise.

PARTS LIST

MAINTENANCE

REPLACEMENT OF FRONT COVER LENS

The front cover lens is loaded in from the inside of the helmet. To replace the front
cover lens follow the steps below:

•   Undo the lens retaining clip by pulling down both tabs together.

•   Lift bottom of the cartridge along with the holding cradle, pull towards you and

place to one side. (Please note the auto darkening filter is still attached to the
helmet via the shade potentiometer).

•   Remove the old lens by pushing from the outside of the helmet and dispose of in
the appropriate manner.

•   Remove protective film from both sides of the new cover lens and place into the
correct position.

•   Replace cartridge by inserting the two prongs at the top of the cradle into the slots
in the shell and lowering back end down.

•   Once in place, close the retaining clip by pushing over location prongs.

•   Only use genuine Parweld cover lenses as using lower grade lens may cause

warping and allow spatter to damage the cartridge, invalidating the warranty. This
may also reduce the impact rating.

NOTE- Do not use the helmet without the cover lens in place

REPLACEMENT OF INNER COVER LENS

•   The welding inner cover lens is removed by pulling out the top edge.

•   To assemble the new inner cover lens, remove the protective film from both sides.

Place by inserting one edge under the frame at the side and gently bending the
lens in the middle part to enable insertion under the frame at the other side.

REPLACEMENT OF WELDING FILTER

•   Remove the shade adjusting knob from the outside of the helmet and unscrew the
locking nut below,

•   Undo the lens retaining clip by pulling down both tabs together.

•   Lift bottom of the cartridge along with the holding cradle, pull towards you and

remove filter.

INSPECTION

•   Carefully inspect your Parweld auto darkening welding filter regularly.

•   Cracked, pitted or scratched filter glass or cover lenses reduce vision and

seriously impair protection.

•   These should be replaced immediately to avoid damage to the eyes.

•   Inspect the complete helmet frequently and replace any worn or damaged parts.

CLEANING

•   Clean the helmet with mild soap and a damp cloth.

•   Clean the welding filter with clean lint-free tissue or cloth.

•   Do not immerse in water.

•   Do not use solvents.

FAULT FINDING

IRREGULAR DARKENING

•   Headband has been sent unevenly so the distance between the eyes and the lens
is different from the left to the right.

AUTO DARKENING FILTER DOES NOT DARKEN OR FLICKERS

•   Front cover lens is soiled - clean or replace.

•   Photo sensors are dirty, wipe clean with a soft lint-free cloth.

•   Welding current is too low, select the slow position on the filter and ensure the

view of the weld is unobstructed.

•   Change to high sensitivity.

POOR VISION

•   Ensure the cover lens and the filter cartridge are clean.

•   Ensure the shade number is correct and adjust accordingly.

•   Ensure ambient light is not too low.
