General safety recommendations
Safety instructions
These instructions contain important information which
either supplements or supersedes other instruction re-
lating to this product� Read these instructions carefully
before commencing operation�
Furthermore, the installation and use of the device
must follow the instructions given in the internation-
al standard: IEC 60974-9 Arc welding equipment
Part 9�
Installation and use
Use of personal protective equipment:
• The arc and its reflecting radiation damage unpro -
tected eyes� Shield your eyes and face appropriately
before you start welding or observe welding� Also
note the different requirements for the darkness of the
screen in the mask as the welding current changes�
• The arc radiation and spatters burn unprotected
skin� Always wear protective gloves, clothing and foot-
wear when welding�
• Always wear hearing protection if the ambient noise
level exceeds the allowable limit�
General operating safety
• Exercise caution when handling parts heated in
welding� For example, the tip of the welding torch, the
end of the welding rod and the work piece will heat to
a burning temperature�
• Never carry the device or suspend it by the carrying
strap during welding�
• Do not expose the machine to high temperatures, as
this may cause damage to the machine�
• Keep the torch cable and earthling cable as close
to each other as possible throughout their length�
Straighten any loops in the cables� This minimizes
your exposure to harmful magnetic fields, which may
interfere with a pacemaker, for example�
