3.2 ENVIRONMENT
The SANARG 160P models are designed for use in adverse environments with an IP23S
rating.
Examples of environments with increased adverse conditions are -
•
With its small, lightweight and portable form factor, the 160P are ideal for use in locations in
which freedom of movement is restricted, so that the operator is forced to perform work in
cramped (kneeling, sitting or lying) positions.
•
The external case is constructed of non-conductive ABS plastic for use in locations which are
fully or partially limited by conductive elements, and in which there is a high risk of
unavoidable or accidental contact by the operator, or
•
In wet or damp hot locations where humidity or perspiration considerably reduces the skin
resistance of the human body and the insulation properties of accessories.
Environments with adverse conditions do not include places where electrically
conductive parts are in the near vicinity of the operator, which can cause
increased hazard, have been insulated.
3.3 MACHINE GROUNDING & HIGH FREQUENCY INTERFERENCE
3.3.1 GROUNDING
The welder must be properly grounded. Check the local codes and the National Electric
Code (NEC) book for proper grounding regulation.
3.3.2 HIGH FREQUENCY INTRODUCTION
The 160P is an inverter power sources that produces many high frequency signals that
may cause other equipment to perform adversely. The importance of correct installation of the
unit, and other high frequency welding equipment cannot be over-emphasized. Interference due
to high frequency starting or even in a stabilized arc is almost invariably traced to improper
installation. The following information is intended as a guide for personnel installing high
frequency welding machines.
