NOTE!
* indicates data tested by ESAB Group, Inc.
The recommended time delay fuse or circuit breaker size is 20 amp. An individual branch circuit capable of
carrying 20 amperes and protected by fuses or circuit breaker is recommended for this application. Fuse
size is based on not more than 200 percent of the rated input amperage of the welding Power Source (Based
on Article 630, National Electrical Code)
ESAB continuously strives to produce the best product possible and therefore reserves the right to change,
improve or revise the speci fications or design of this or any product without prior notice. Such updates or
changes do not entitle the buyer of equipment previously sold or shipped to the corresponding changes,
updates, improvements or replacement of such items.
The values specified in the table above are optimal values, your values may differ. Individual equipment may
differ from the above specifications due to in part, but not exclusively, to any one or more of the following;
variations or changes in manufactured components, installation location and conditions and local power grid
supply conditions.
The thermal protection switch is rated at 80°C.

3.03 Environment

These units are designed for use in environments with increased hazard of electric shock.
A. Examples of environments with increased hazard of electric shock are:
1. In locations in which freedom of movement is restricted, so that the operator is forced to perform the work in a cramped (kneel-
ing, sitting or lying) position with physical contact with conductive parts.
2. In locations which are fully or partially limited by conductive elements, and in which there is a high risk of unavoidable or ac-
cidental contact by the operator.
3. In wet or damp hot locations where humidity or perspiration considerable reduces the skin resistance of the human body and
the insulation properties of accessories.
B. 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.

3.04 Location

Be sure to locate the welder according to the following guidelines:
A. In areas, free from moisture and dust.
B. Ambient temperature between 32 to 104° F (0 to 40° C).
C. In areas, free from oil, steam and corrosive gases.
D. In areas, not subjected to abnormal vibration or shock.
E. In areas, not exposed to direct sunlight or rain.
F. Place at a distance of 12"(300mm) or more from walls or similar that could restrict natural air flow for cooling.
G. The enclosure design of this Power Source meets the requirements of IP23S as outlined in EN 60529. This provides adequate
protection against solid objects (greater than 1/2", 12mm), and direct protection from vertical drops. Under no circumstances
should the Power Source be operated or connected in a micro environment that will exceed the stated conditions. For further
information please refer to EN 60529.
H. Precautions must be taken against the power source toppling over. The power source must be located on a suitable horizontal
surface in the upright position when in use.
WARNING
This equipment should be electrically connected by a qualified electrician.
