SECTION 1: SAFETY INSTRUCTIONS AND WARNINGS
!
WARNING
PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. KEEP CHILDREN AWAY.
PACEMAKER WEARERS KEEP AWAY UNTIL CONSULTING YOUR DOCTOR. DO NOT LOSE THESE INSTRUCTIONS.
READ OPERATING/INSTRUCTION MANUAL BEFORE INSTALLING, OPERATING OR SERVICING THIS EQUIPMENT.
Welding products and welding processes can cause serious injury or death, or damage to other equipment or
property, if the operator does not strictly observe all safety rules and take precautionary actions.
Safe practices have developed from past experience in the use of welding and cutting. These practices must be
learned through study and training before using this equipment. Some of these practices apply to equipment
connected to power lines; other practices apply to engine driven equipment. Anyone not having extensive training
in welding and cutting practices should not attempt to weld.
Safe practices are outlined in the American National Standard Z49.1 entitled: SAFETY IN WELDING AND CUTTING.
This publication and other guides to what you should learn before operating this equipment are listed at the
end of these safety precautions. HAVE ALL INSTALLATION, OPERATION, MAINTENANCE, AND REPAIR WORK
PERFORMED ONLY BY QUALIFIED PEOPLE.

* As a rule of thumb, start with a shade that is too dark to see the weld zone. Then go to a lighter
shade which gives sufficient view of the weld zone without going below the minimum. In oxyfuel gas
welding, cutting, or brazing where the torch and/or the flux produces a high yellow light, it is desirable
to use a filter lens that absorbs the yellow or sodium line of the visible light spectrum.
