General Safety Measures
It is essential to read the entire operation manual prior to the first use. If there are any doubts arising regarding connection and
operation of the device, consult the manufacturer (servicing department).
Protect the device against moisture, rain and dust.
TO PROVIDE FOR MAXIMUM SAFETY, FOLLOW CAREFULLY THE INSTRUCTIONS BELOW:
The user shall be held liable for professionally done installation and for use of the machine in conformity with the manufacturer’s data.
If the user detects any electromagnetic faults, he is responsible for removing the same and use of the manufacturer’s technical
assistance. In many a case, just grounding the welding area is sufficient to remove the troubles. There are yet other cases, when
developing an electromagnetic screen to cover the current source and the entire working area with a connected voltage filter may be
helpful. In any case, the electromagnetic faults have to be removed so that they are not disturbing the user any more.
Caution: For the sake of safety, the current circuit should not be grounded. Any alteration of the grounding system should be done by
competent authorised personnel able to estimate the consequences and risks of the alterations done.
Location Requirements
Prior to installation and starting the machine up, the user should account for any possible electromagnetic faults in the area.
The factors listed below should be taken into account:
a) other supply, control, signalling and telephone cables above the welding machine and under it and also in the adjacent area
b) radio and TV sets, receivers;
c) computers and other control equipments;
d) safety and monitoring instruments;
e) condition of health of those present, e.g. pacemakers, hearing aids etc.
f) meters used for calibrations;
g) protection of the other instruments and devices in the welding machine area. These devices should be compatible.
Supplementary protection measures may be required.
h) Daytime, in which welding or other works are to be performed.
The area that may produce effects on the welding machine operation is subject to the building structure and other activities being
carried out at a time of welding. The area may be as large as to near the neighbouring buildings.
Emission Reduction
Source Current Supply
As instructed by the manufacturer, the welding machine must be connected to the source current supply. If faults occur, it will be
apparently necessary to provide for supplementary protective measures, such as a filter installed on the lead. The current leads of
fixed welding machines should be protected with an insulation tube along the entire length of the cable. Welding cable should be as
short as possible.
Special Safety Regulations
Introduction
The arc welding machines were developed thanks to many-year experience in the welding profession. Provided that the methods of
operation prescribed by the manufacturer are provided, they will guarantee a high level of operating safety in addition to very good
welding properties. For this reason, the management should take care to ensure that every person working with the machine has
access to this information.
General Precautions
Protection against Burns
Sparkles, clinker, hot metal and radiation may be a serious hazard in arc welding putting eyes and skin at risk. The closer is the user
or another person to the welding site, the bigger is the hazard they are exposed to. The user and any other persons working
