1. Introduction
Thank you for your purchase of the Parweld XR937H Welding Helmet. Please read and
understand this instruction manual thoroughly to ensure correct, safe and effective use
of the helmet. Failure to do so can result in serious injury. Keep this manual in a safe
place for future reference.
2. Product Features
The XR937H uses a thin Liquid Crystal Display coupled to which sensors react instantly to
the arc being struck and switch the display to block the light before it is registered by the
eye. The dark shade can be adjusted from 5-13 DIN depending upon the application. The
lens system also includes permanent UV and IR filters which ensure full time protection
for the user even in the light state or a failure mode. The helmet uses a true colour filter
which improves the contrast and visibility especially with green LED’s and the colours of
the ARC are more realistic.

Adjust the rake angle so the viewing window is in front of the eyes and the base of the
helmet sits close to the chest in the down position.
Slacken the external adjusting knob on the side and then move the tab inside to set
the rake angle.
Adjust the headband diameter so the helmet
slips over your head.
This will improve the long term comfort
when wearing the helmet.
Then adjust the two other headbands so
that they touch the top of your head in
the normal wearing position.

6. Operating Instructions
• Open the package and take out the
helmet. Check to make sure it is intact and
undamaged including the lithium battery,
installed on the helmet.
• Do not use the Welding Helmet if the lens
is cracked or if the lens is dirty.
• Adjusting the switch sensitivity –the
operator can adjust the amount of
light required for the lens to darken,
depending on working conditions. Reduce
sensitivity to avoid interference from
lighting or other welders nearby. When
working with a low power or TIG welding
high sensitivity is preferred.
• Adjusting dark to clear delay –the time
for the filter to return to clear state can
be adjusted, depending on working
conditions level. When welding is stopped,
the filter screen automatically changes
from dark to clear state according to the
time setting selected. For high amperage
select a long delay or for TIG applications
to prevent flickering at low power.
Short delay is preferred for spot welding
applications.
• Adjusting the Shade Range –the operator
can select (DIN) variable shades from 9 to
13 at the turn of the shade knob. Refer to
Recommended Shade Numbers on page 5
for shade selection.
• This helmet provides protection for arc
welding purposes only. It is not suitable
for laser welding processes. The Welding
Helmet will not protect against severe
impact hazards. The Welding Helmet will
also not protect against explosive devices
or corrosive liquids.
• Use only at temperatures within the
operating range.
7. Maintenance
To Replace the Cover Lens
• Remove the Front Lens Cover by sliding
the 2 tabs at the base of the filter unit
on the inside of the helmet to the unlock
position.
• Lift up the lower end of the frame and the

the base.
• Clean the filter lens with a lint-free tissue
or cotton cloth.
• Do not immerse the lens in water or any
other liquid. Do not use abrasives, solvents
or oil based cleaners.
• Do not remove the Auto-Darkening
filter from the Auto-Darkening Welding
Helmet. Do not try to open the filter.
• Clean filter’s surfaces regularly. Protect
filter from contact with any liquid and
dirt. Do not immerse the filter in water.
• Should the Auto-Darkening Welding
Helmet not darken upon striking an arc,
stop welding immediately and check if the
battery needs replacing. If the lens still
does not darken, have the helmet checked
by an authorized service technician.
• Replace the Front Lens Cover if it is
