INSTALLATION
A. ESAB welding power sources have been designed to high standards of electromagnetic compatibility. However, arc
welding, by its very nature, generates radio-frequency energy and may cause interference. By installing and using the
equipment correctly, in accordance with these instructions, the problems of interference may be minimized.
B. If this equipment is used in domestic areas, eg. for repair or maintenance, particular care should be taken. The time of
day should be chosen and the duration of welding limited, to minimize any potential problems.
C. If this equipment caused interference the guidance given below should be considered. If a solution cannot be found
please contact your distributor or the manufacturer.
D. Before installing this welding equipment an assessment should be made of potential problems that may occur. It is good
practice not to install welding equipment next to computers or safety critical control circuits, eg electronic machine
guards, unless they have been suitably protected.
E. Primary cabling and welding cables should be kept separate from other main wiring and control, signalling or com-
munications (eg telephone) cables. If interference occurs then greater separation or re-routing should be considered.
Welding cables should be kept as short as practically possible.
F. Interference may also be reduced by separating the welding equipment from the other equipment affected. A partition,
brick wall or particularly, a metal screen will also reduce interference. Earthing and equi-potential bonding should also
be considered but guidance should be sought from a competent person, the distributor or manufacturer.
G. This equipment should be routinely maintained according to the manufacturers instructions and using only approved
spare parts.
H. All access and service door and covers should be closed and properly fastened when the equipment is being used. This
equipment should not be modified in any way except for those changes and adjustments approved by the manufac-
turer.
Connection to Primary Power
The Miniarc 10 APS can be used on 230V or 11V single phase electricity supplies.
On 230V a standard 20A breaker is adequate for most MMA or TIG welding applications. For higher duty work, with 1/8”
(3.2mm) electrodes at 10A for example, A 30A breaker or slow fuse must be used.
On 11V supplies a 20A circuit breaker should be used corresponding with a supply of not less than 2.KVA.
The unit contains sensing circuiting which automatically adjusts itself to match the mains input supply, 230V or 11V as
necessary. No internal adjustments are required.
IMPORTANT!
The green earth lead must be connected to a good earth ground.
