SAFETY AND INSTALLATION WELDSKILL 200AC/DC INVERTER
3.03 Environment
These units are designed for use in environments with increased hazard of electric shock as outlined in AS 60974.1
and AS 1674.2. Additional safety precautions may be required when using unit in an environment with increased
hazard of electric shock. Please refer to relevant local standards for further information prior to using in such areas.
A. In locations in which freedom of movement is restricted, so that the operator is forced to perform the work in
a cramped (kneeling, sitting or lying) position with physical contact with conductive parts.
B. 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.
C. 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 increased hazard of electric shock do not include places where electrically conductive parts in
the near vicinity of the operator, which can cause increased hazard, have been insulated.

WARNING
Thermal Arc advises that this equipment be electrically connected by a qualified electrician.
3.05 High Frequency Introduction
The importance of correct installation of high frequency welding equipment cannot be overemphasized. Interference
due to high frequency initiated or stabilised arc is almost invariably traced to improper installation. The following
information is intended as a guide for personnel installing high frequency welding machines.
!
WARNING EXPLOSIVES
The high frequency section of this machine has an output similar to a radio transmitter. The machine
should NOT be used in the vicinity of blasting operations due to the danger of premature firing
