Instructions
WARNING
Please read and understand all instructions prior to using the Parweld XR938H
True Colour Light Reactive Welding and Grinding Helmet.
GENERAL INFORMATION
This Parweld XR938H True Colour 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 when thesehazards are present. All Parweld XR938H light reactive welding filters are suitable for 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 XR938H helmet is not suitable for “overhead” welding applications, laser welding, laser cutting, gas welding and gas cutting. In the event of electronic failure, the welder remains protected against UV and IR Radiation according to Shade 16
The Parweld auto darkening filter should always be used with original Parweld front and inside cover lens. The manufacturer is not responsible for any modifications to the welding filter or use of the filter in helmets of any other make. Protection can be seriously impaired if unapproved modifications are made.
Please dispose of packaging for the product in a responsible manner. It is suitable for recycling. Please help protect the environment. Take the packaging to the local waste recovery site 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 waste recovery site and dispose in the correct manner.

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
-
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°. -
ON/OFF
The solar unit automatically switches on when exposed to light created by welding. -
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. -
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. -
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. -
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.
PARTS LIST
MAINTENANCE
REPLACEMENT OF FRONT COVER LENS
- Remove the front cover lens by pulling out the lower edge at the notch at the front of the filter.
- Make sure the protective films are removed from new front cover lenses.
- Place the new front cover lens in the recess at the front of the helmet
- Insert the cover lens under the lugs on the left hand side of the filter. Then flex the cover lens so that it can be inserted under the lugs on the right hand side of the filter.
- Only use original Parweld cover lenses. Use of lower-grade cover lenses may cause warping and allow spatter to damage the filter, so invalidating the warranty. This may also reduce the impact rating.
NOTE – Do not use the helmet without the cover lens in place
REPLACEMENT OF INSIDE COVER LENS
- Remove the inside cover lens by pulling out the top edge at the notch at the back of the filter.
- Mount the new inside cover lens after you have removed the protective film.
- Insert the cover lens under the frame at one side, bend the cover lens in the middle and place it under the frame at the other side.
REPLACEMENT OF WELDING FILTER
- Prise off the shade adjusting knob from the outside of the helmet and unscrew the locking nut below.
- From inside the helmet push the spring at the bottom of the filter down and pull it towards you so that it clears the location tabs.
- Lift the bottom of the filter and pull the filter towards you so that it sits on the frame.
- Now lift the retainer spring to the upright position then pass the shade potentiometer cable sliding the filter towards you if needed.
- Once the cable is free, you can remove the filter and mount the new filter.
INSPECTION
- Carefully inspect your Parweld Auto Darkening Welding Filter regularly.
- Cracked or scratched filter glasses or cover lenses reduce the field of view and seriously impair protection. They 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 set 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 it.
- 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 glass and the filter cartridge are clean.
- Ensure the shade number is correct and adjust accordingly.
- Ensure ambient light is not too low.
