Auto-darkening 

Welding Helmet

Dress properly

6. 

.  Do not wear loose 

clothing or jewelry as they can be 

caught in moving parts.  Protective 

gear is essential to protect against 

welding rays, some examples are: a 

leather welding apron, welding sleeves, 

jeans without cuffs, work boots.  Wear 

restrictive hair covering to contain long 

hair.

7. 

Use eye and ear 

protection

.  

When 

welding,  wear ANSI-

approved impact safety 

goggles under the Welding Helmet.

  

Wear a NIOSH-approved respirator 

and hearing protection when welding.

Stay alert

8. 

.  Watch what you are doing, 

use common sense. Do not weld when 

you are tired.

check for damaged parts

9. 

.  Before 

using any helmet, any part that appears 

damaged should be carefully checked 

to determine that it will operate 

properly and perform its intended 

function. Check for alignment and 

binding of moving parts; any broken 

parts or mounting fixtures; and any 

other condition that may affect proper 

operation. Any part that is damaged 

should be properly repaired or replaced 

by a qualified technician. Do not use 

the helmet if any switch does not 

operate properly.

Replacement parts and accessories

10. 

.  

When servicing, use only identical 

replacement parts.  Use of any other 

parts can render helmet ineffective, 

possibly causing eye damage, and 

will void the warranty.  Only use 

accessories intended for use with this 

helmet.  Approved accessories are 

available from Harbor Freight Tools.

Do not weld if under the influence 

11. 

of alcohol or drugs

.  Read warning 

labels on prescriptions to determine if 

your judgment or reflexes are impaired 

while taking drugs. If there is any 

doubt, do not weld.

WARNING

INHALATION HAzARD: 

Welding and plasma cutting produce 

TOxIc FUMES.

Exposure to welding or cutting exhaust 

fumes can increase the risk of developing 

certain cancers, such as cancer of the 

larynx and lung cancer.  Also, some 

diseases that may be linked to exposure 

to welding or plasma cutting exhaust 

fumes are:

• Early onset of Parkinson’s Disease

• Heart disease 

• Ulcers

• Damage to the reproductive organs

• Inflammation of the small intestine or 

stomach 

• Kidney damage

• Respiratory diseases such as 

emphysema, bronchitis, or pneumonia

Auto-darkening 

Welding Helmet

pRODUcT FEATURES/

OpERATION

At the moment the welding operation 

is started, the filter screen automatically 

changes from clear to dark in only 

1/25,000th of a second.

Dark to clear delay adjustment:  

Operator can vary the time for the filter to 

return to clear state.  At the moment welding 

is stopped, the filter screen automatically 

changes from dark to clear state according 

to the time setting you select.

Switch Sensitivity Adjustment:  The 

operator can adjust the amount of light 

needed to cause the Lens to darken.

This Welding Helmet utilizes high 

performance solar cells as power supply, 

and has built-in battery(ies) as power 

backup, see below.  Under normal welding 

conditions, users can expect a battery 

lifetime of more than 6 years.

User-selectable variable shades from 

9 to 13 are adjusted at the turn of a shade 

knob (shade variable).  This product is in 

full conformity with related DIN, ISO, EN379 

safety standards and ANSI Z87.1-2003 

standard.

Auto-darkening filters provide 

protection against UV and IR radiation to the 

user’s eyes and face, even in the clear state.
