TECHNICAL SPECIFICATIONS

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 solar unit automatically switches on when exposed to light.

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.

RECOMMENDED SHADE NUMBERS

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 outwards at the base of the lens using the finger slot provided.
• Make sure the protective films are removed from new cover lens.

• 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.

• Once the cable is free the filter can be removed.

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.

• 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.

FAULT FINDING

IRREGULAR DARKENING

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.
