3.02 Environment
The 300AP is 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 300AP is 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.
3.03 Machine Grounding & High Frequency Interference
3.03.01 Grounding
The welder must be properly grounded. Check the local codes and the National Electric Code (NEC)
book for proper grounding guidelines and regulations.
3.03.02 High Frequency Introduction
The 300AP units are inverter power source that produce 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.
