SECTION 1 − SAFETY PRECAUTIONS −

READ BEFORE USING

Y Warning: Protect yourself and others from injury — read and follow these precautions.

1-1. Symbol Usage

Means Warning! Watch Out!
There are possible hazards with
this procedure! The possible
hazards are shown in the ad­joining symbols.

Y Marks a special safety message.

This group of symbols means Warning! Watch
Out! possible ELECTRIC SHOCK, MOVING
PARTS, and HOT PARTS hazards. Consult sym­bols and related instructions below for necessary
actions to avoid the hazards.

. Means “Note”; not safety related.

1-2. Hazards

ARC RAYS can burn eyes and skin.

Arc rays from the welding process produce intense visible and invisible (ultravio­let and infrared) rays that can burn eyes and skin. Sparks fly off from the weld.

D Wear a welding helmet fitted with a proper shade of filter to protect your

face and eyes when welding or watching (see ANSI Z49.1 and Z87.1 listed
in Safety Standards). Refer to Shade and Sensitivity charts in Sections 3-4
and 3-5.

D Wear approved safety glasses with side shields under your helmet.
D Use protective screens or barriers to protect others from flash and glare;

warn others not to watch the arc.

D Wear protective clothing made from durable, flame-resistant material

(leather and wool) and foot protection.

WELDING HELMETS do not provide unlimited eye, ear and
face protection.

D Use impact resistant safety spectacles or goggles and ear protection at all

times when using this welding helmet.

D Do not use this helmet while working with or around explosives or

corrosive liquids.

D Do not weld in the overhead position while using this helmet.
D Inspect the auto-lens frequently. Immediately replace any scratched,

cracked, or pitted cover lenses or auto-lenses.

NOISE can damage hearing.

Noise from some processes or equipment can damage hearing.
D Wear approved ear protection if noise level is high.

Off (clear state − No. 3) 15−20
minutes after the last arc. Press
the On button to resume
welding.

3-3. Lens Delay Control (Variable Shade Models Only)

1 Lens Delay Control
The lens delay control is used to

adjust 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. Adjusts from slow to fast.
