IMPORTANT SAFETY INSTRUCTIONS
FUMES AND GASES can be hazardous !
Welding produces fumes and gases that are hazardous to your health.
• Keep your head out of the fumes. Do not breathe in the fumes.
• If inside, ventilate the area and/or use exhaust at the arc to remove welding
fumes and gases.
• If ventilation is poor, use an approved air-supplied respirator.
• Read the manufacturer’s instructions for metals, consumables, coatings, cleaners, and degreasers.
• Do not weld in locations near degreasing cleaning, or spraying operations. The heat and rays of the
arc can react with vapors to form highly toxic and irritating gases.
• Do not weld on coated metals, such as galvanized, lead, or cadmium plated steel, unless the
coating is removed from the weld area, the area is well ventilated, and if necessary, while wearing
an air-supplied respirator.The coatings and any metals containing these elements can give off toxic
fumes if welded.
• Work in a confined space only if it is well ventilated, or while wearing an air-supplied respirator.
Always have a trained watchperson nearby. Welding fumes and gases can displace air and lower
the oxygen level causing injury or death. Be sure the breathing air is safe.
California Proposition 65 Warnings !
• Welding or cutting equipment produces fumes or gases which contain chemicals known to the
State of California to cause birth defects and, in some cases, cancer. (California Health & Safety
Code Section 25249.5 et seq.)
ARC RAYS can burn eyes !
Never look at arc welding without proper eye protection. Arc rays from the
welding process produce intense visible and invisible (ultraviolet and infrared)
rays that can burn eyes and Skin, Hot sparks fly off from the weld and can
burn eyes and skin.
Wear a welding helmet fitted with a proper shade of lens to protect your
face and eyes when welding or watching.
• Wear approved safety glasses with side shields under your helmet.
• Use protective screens or barriers to protect others from flash and glare, warn others in the area
not to watch the arc.
• Wear protective clothing made from durable, flame resistant materials, leather welding gloves
and full foot protection.
WELDING can cause fire or explosion !
Welding on closed containers, such as tanks, drums, or pipes, can cause
them to explode.Sparks can fly off from the welding arc. The flying sparks,
hot work piece, and hot equipment can cause fires and burns, Accidental
contact of electrode to metal objects can cause sparks, explosion,
overheating,or fire. Check and be sure the area is sale before doing any
welding.
• Be alert that welding sparks and hot materials from welding can easily go through small cracks
and openings to adjacent areas.
• Do not weld on closed containers such as tanks, drums, or pipes; unless they are properly
prepared according to AWS F4.1 standards.
• Connect work cable to the work as close to the welding area as practical to prevent welding
current from traveling long, possibly unknown paths and causing electric shock and fire
hazards.
• Never use arc welder to thaw frozen pipes.
• Remove electrode from holder when not in use.
• Wear oil-free protective garments such as leather gloves, heavy shirt, trousers with no cuffs,
high shoes, and a cap.
• Always keep a fire extinguisher readily available and watch for fire.
• Protect yourself and others from flying sparks and hot metal.
• Do not weld where flying sparks can strike flammable material.
• Remove all flammable materials from the welding area. If this is not possible, tightly cover them
with approved covers
• Be aware that welding on a ceiling ,floor, bulkhead, or partition can cause fire on the hidden side.
• Remove any combustibles, such as butane lighters or matches, from yourself and the surroundings
near the welding location before doing any welding.

TROUBLE SHOOTING
AUTO DARKENING LENS DOES NOT DARKEN OR FLICKER
- Check the lens cover for dirt and spatter that may be blocking the arc sensors.
- The sensors are dirty, wipe them clean with a soft lint-free cloth.
- Check the sensitivity setting recommendations and increase the sensitivity if possible.
- Increasing lens delay 0.1-0.3 second may also reduce flickering.
- Check batteries and verify that they are in good condition and installed properly.
- Battery terminals and the contact surface of the lens are dirty or oxidized(clean both) .
- Shade adjustment knob is on "GRIND" position, set helmet on “WELD” and/or proper shade
from “5-13”.
THE 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 in small increments. In extreme light conditions, it may be
necessary to reduce the surrounding light levels.
SLOW SWITCHING
- The operating temperature is too low, don’t use at temperatures of below -5 ℃（+23℉）.
POOR VISION
- The cover lens and the lens cartridge is dirty or damaged, clean the dirty components and
replace the damaged ones.
- Ensure ambient light is not too low.
- Ensure the shade number is correct and adjust accordingly.
IRREGULAR DARKENING
- Headband has been set unevenly so the distance between the eyes and the lens is different
from the left to the right side.
If the described malfunctions cannot be solved, stop using the helmet immediately and contact
the nearest distributor.
