ARCMASTER 401S POWER SOURCE

Manual 0-5345 3-1 INSTALLATION, OPERATION AND SETUP

SECTION 3:

INSTALLATION, OPERATION AND SETUP

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.

3.03 Ventilation

WARNING

Since the inhalation of welding fumes can

be harmful, ensure that the welding area is

effectively ventilated.

3.04 Mains Supply Voltage

Requirements

The Mains supply voltage should be within ± 15% of the

rated mains supply voltage. Too low a voltage may cause

poor welding performance. Too high a supply voltage

will cause components to overheat and possibly fail.

The Welding Power Source must be:

• Correctlyinstalled, if necessary,by a qualied

electrician.

• Correctlyearthed(electrically)inaccordancewith

local regulations.

• Connectedtothecorrectsizepowerpointandfuse

as per the Speciﬁcations on page 2-4 (2-6).

WARNING

Any electrical work must be carried out by a

qualiﬁed Electrical Tradesperson.

3.01 Environment

These units are designed for use in environments with

increased hazard of electric shock as outlined in EN

60974-1.

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 (kneeling, 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 accidental 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.

3.02 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.

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 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 12mm), and direct protection from vertical

drops. Under no circumstances should the unit be

operated or connected in a micro environment that will
