3. SELECT THE SHADE NUMBER

The shade is infinitely adjustable between shade 9 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 using the delay knob on the inside of the filter (the side
you look through) it can be set variably between MAX which is 1.0 second or MIN
which is 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 after glow.

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 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 this means 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.

MAINTENANCE

REPLACEMENT OF FRONT COVER LENS

•   Remove the front cover lens by pulling outwards at the base of the lens using the
finger slot provided.

•   Make sure the protective films are removed from new cover lens.

•   Place the new cover lens in the recess at the front of the helmet

•   Locate the cover lens under the lugs at the left of the filter and then flex the lens

so that it can be inserted under the lugs on the right had side of the filter.

•   Only use genuine Parweld cover lenses, using lower grade lens 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 INNER COVER LENS

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

•   The new inner cover lens is assembled after the protective film is removed. Locate

one of the sides by inserting the edge under the frame at the side and bend the
lens in the middle part and locate the lens under the frame at the other side.

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.
