PRETUL 29978 Electronic Welding Helmet User Manual

PRETUL 29978 Electronic Welding Helmet

Product Features

• Durable design, housing materials high and low temperature and corrosion resistant housing materials; and flame retardant.
• Clear view of the work area, either before or during welding; this translates into better quality and higher efficiency.
• High protection against ultraviolet (UV) and infrared (IR) radiation. Equipped with two Li-Mn batteries and solar cells that help extend battery life.

WARNINGS

• The masks are NOT suitable for laser welding or laser cutting applications.
• The outside of the lens must be fitted with the protective plate to prevent potential irreparable damage.
• Replace the lens and protective plate if broken or scratched as soon as possible, as this decreases the protection and field of vision.
• Select the shade number before starting work, depending on the welding process.
• The operating temperature range is from -5 °C to 55 °C.
• When the ambient temperature is below the lower limit, the response speed of the lens will be slowed down a little, no other protection will be affected.
• Do not store near a heat source or high humidity.
• Do not clean the lens frame with alcohol, gasoline or diluted solvent, or immerse it in water.
• Change the sweatband frequently.
• Replace defective parts only with parts authorized by the supplier.
• Check the adjustment of the band before each use.
• Check that the lenses are clean and the sensors are free of dust.
• Inspect all parts before each use for deterioration or damage.
• Do not make any modifications to the facepiece or lenses that are not specified in these instructions. Do not use unspecified replacement parts. Doing so will void the warranty and expose you to risk of personal injury.
• Failure to follow these precautions may result in severe injury.

Operation

BEFORE FIRST USE

• Remove the protective label from the battery (see page 3).
• Remove the protective film from both sides of the lens.

Adjusting the helmet

• Adjust the band diameter with the adjustment knob on the back of the head. Push the knob clockwise to tighten; or turn counterclockwise to loosen the band.
• Adjust the upper band to one of the preset positions for proper depth.
• To adjust the viewing angle, reposition the ratchet mechanism located on the side of the suspension to the desired elevation position. Once the desired angle is achieved, make sure the locking pins are secure. The hull should be able to be folded down, but should not deflect downward when in place for welding.
• To adjust the distance between the user and the ADF, the mask has 3 positions. Turn the knobs on the side of the suspension to loosen the clamping screws. Move the screw to the position that best suits your needs, make sure that the screw fits correctly in the notches of the suspension and tighten by turning the knob. This must be done one side at a time, and both sides must be in the same position for proper operation of the auto darkening filter.

Battery indicator

• lf the “LOW Battery” LED lights up, the batteries must be replaced (see page 3).
• Delay control
  When welding is finished, the display window automatically changes from dark to light, but with a preset delay as compensation.
  The delay time can be set from MIN (0.1 second) to MAX (1.0 second) by means of the infinite dial knob.
  The minimum delay is suitable for spot or short welding. The maximum delay is suitable for heavy current welding and reduces arc eye fatigue. Selections between MIN and MAX are suitable for most indoor and outdoor welding operations.

• Sensitivity Control
  The sensitivity can be set from LO (low) to HI (high) using the infinite dial knob. The LO setting is suitable for ambient light or in close proximity to another welding machine. The HI setting is suitable for low amperage welding and for welding in areas with low light conditions, especially with low amperage argon gas arc welding. Selections between LO and HI are suitable for most indoor and outdoor welding operations.

• Shade Control
  Turn the outer knob for shade control from 9 to 13 according to the welding process to be used (Refer to the recommended shade selection chart). GRIND shade 4 grinding mode prevents the filter lens from self-darkening for grinding applications.

Maintenance

• Wipe the lens with a clean, lint-free cloth with glass detergent. Do not immerse in water or other liquid. Never use solvents or oil to dilute the detergent.
• Use neutral detergent to clean the headband.
• Never strike the lens directly.
• Replace the front cover lens if it is damaged (cracked, scratched, chipped or damaged (cracked, scratched, pitted or dirty). To remove the front cover, place your finger or thumb in the recess and fold up the lens until it is free from the guides. Remove the protective film before installing a new one. Make sure all guides hold the new lens after installing the new lens.
• Replace the inner cover lens if damaged (cracked, scratched, pitted or dirty). Place your finger or thumb in the recess and bend up the inner cover lens until it releases from one edge, then remove any protective film before installing a new one ..

Troubleshooting

Clean or replace
Arc sensors are not free| Clean the sensor surface
Soldering current is to low| Adjust sensitivity to maximum
Low battery| Replace battery
Slow reaction| Ambient temperature is very low| Do not use under 5°C
Sensitivity configuration is very low| Configure sensitivity correctly
Filter is not clear| Protection is stained| Clean or replace protection
Protection filter was nor

removed

| Remove the protection film
Lens filters have stains| Clean both sides of the lens filter
Ambient light is insufficient| Turn off the light in the work place
Shadow number was not configurated properly| Adjust the helmet nuts

Warning
You should stop using the product immediately and contact the distributor if the above questions cannot be resolved.
