OPERATING INSTRUCTIONS

Hobart Welding Helmets Pro Series Controls

Reset Button
Low Battery Indicator
Variable Shade Control
Sensitivity/Grind Mode Control
Lens Delay Control

Reset Button And Low Battery Indicator

Reset Button
Press Reset button to check if the lens is working properly.
When the Reset button is pressed, the lens should darken twice and return to the clear state. Do not use the helmet if the lens does not function as de-scribed.
Low Battery Indicator
The low battery indicator lights when 2−3 days of battery life re-main.
If battery power is low, install new CR2450 lithium batteries.

Lens Delay Control

The lens delay control is used to ad-just the time for the lens to switch to the clear state after welding. The delay is particularly useful in eliminating bright after-rays present in higher amperage applications where the molten puddle remains bright momentarily after welding. Lens delay adjusts from min (0.10 second) to max (1.0 second).

Variable Shade Control

Use the control to adjust the lens shade in the darkened state to select proper shade control setting based on your welding process. Start at shade 12 and adjust lighter to suit the welding application and your personal preference.

Sensitivity/Grind Mode Control

hobart_welding_helmets_pro_series.sensitivity.png

Weld Mode
Use control to make the lens more responsive to different light levels in various welding processes. Use a Mid-Range or 30−50% sensitivity setting for most applications. It may be necessary to adjust helmet sensitivity to accommodate different lighting conditions or if lens is flashing On and Off. Ad-just helmet sensitivity as follows:

Adjust helmet sensitivity in lighting conditions helmet will be used in.

Turn sensitivity control to lowest setting.
Press Reset button to turn helmet On. Helmet lens will darken twice and then clear.
Face the helmet in the direction of use, exposing it to the surrounding light conditions.
Gradually turn sensitivity setting clock- wise until the lens darkens, then turn sensitivity control counterclockwise until slightly past setting where lens clears. Helmet is ready for use. Slight readjustment may be necessary for certain applications or if lens is flashing on and off.

Grind Mode

Do not weld in the Grind mode; the lens will not darken. To use the Grind mode, turn the Sensitivity control clockwise to the far right position (Grind). To resume welding, return the con-trol to the desired sensitivity setting.

Recommended Sensitivity Settings

Stick Electrode	Mid-Range
Short Circuiting (MIG)	Low/Mid-Range
Pulsed &Spray (MIG)	Mid-Range
Gas Tungsten Arc (TIG)	Mid/High-Range
Plasma Arc Cutting/Welding	Low/Mid-Range
Grind Mode	Grind Position − Far Right(Clockwise)

Description of Hobart Welding

Helmets Pro Series offers a variety of features that make it a top choice for welders. The auto-darkening technology allows the lens to adjust to the brightness of the welding arc, protecting the welder's eyes and reducing strain. The sensitivity controls allow the welder to adjust the lens to their specific needs, and the wide viewing area provides a clear and unobstructed view of the welding area. The helmet is also lightweight and comfortable to wear, with a adjustable headgear. Additionally, the helmet meets ANSI Z87.1+ standards for impact protection and is compatible with respirators.

Maintenance

NOTICE: Never use solvents or abrasive cleaning detergents.
NOTICE: Do not immerse the lens assembly in water.
The helmet requires little maintenance. However, for best performance clean after each use. Using a soft cloth dampened with a mild soap and water solution, wipe the cover lenses clean. Allow to air dry. Occasionally, the filter lens and sensors should be cleaned by gently wiping with a soft, dry cloth.

Troubleshooting of Helmets Pro Series

Trouble	Remedy
Auto lens not ON – auto-lens will not darken momentarily when the Reset button is pressed.	Check batteries and verify they are in good condition and installed properly. Also, check battery surfaces and contacts and clean if necessary. Check battery for proper contact and gently adjust contact points if necessary. This is particularly important if the helmet has been dropped. Verify left and right battery trays are installed on the correct sides.
Not switching – auto-lens stays light and will not darken when welding.	Stop welding immediately. Press the Reset button if lens is Auto-On type. If lens if Manual-On type, make sure the lens is turned On. If power is on, review the sensitivity recommendations and adjust sensitivity. Clean lens cover and sensors of any obstructions. Make sure the sensors are facing the arc; angles of 45° or more may not allow the arc light to reach the sensors.
Not Switching – auto-lens stays dark after the weld arc is extinguished, or the auto-lens stays dark when no arc is present.	Fine-tune the sensitivity setting by making small adjustments to the control by turning it toward the “min” setting. In extreme light conditions, it may be necessary to reduce the surrounding light levels.
Sections of the auto-lens are not going dark, distinct lines separate the light and dark areas.	Stop welding immediately. The auto-lens may be cracked which can be caused by the impact of dropping the helmet. Weld spatter on the auto lens may also cause cracking. (The lens may need to be replaced; most cracked lenses are not covered by warranty).
Switching or Flickering – the auto-lens darkens then lightens when the welding arc is present.	Review the sensitivity setting recommendations and increase the sensitivity if possible. Be sure the arc sensors are not being blocked from direct access to the arc light. Check the lens cover for dirt and spatter that may be blocking the arc sensors. Increasing Lens Delay 0.1 – 0.3 second may also reduce switching.
Inconsistent or lighter auto-lens shading in the dark-state, noticeable on the outside edges and corners.	Referred to as an angle of view effect, auto-darkening lenses have an optimum viewing angle. The optimum viewing angle is perpendicular or 90° to the surface of the auto-lens. When that angle of view varies in the dark-state, welders may notice slightly lighter areas at the outside edges and the corners of the lens. This is normal and does not represent any health or safety hazard. This effect may also be more noticeable in applications where magnifying lenses are used.

Hobart Warranty

Hobart auto-darkening lens helmets are warranted for two (2) years from the date of purchase. Proof of purchase is required for warranty transactions so it is imperative that a copy of the original invoice or sales receipt be retained.
