SAFETY PRECAUTIONS
PERSONAL PROTECTION
1. For safety reasons, protective gloves must be worn during welding. These
gloves protect you from electric shock (circuit voltage at no load). It also
protects you from heat radiation and splashing drops of hot metal.
2. Wear insulated shoes. Open shoes are not suitable as drops of hot metal
can cause burns.
3. Do not look into the welding arc without face and eye protection. Always
use a high-quality welding helmet with an intact protective filter.
4.
Notice
Persons with implanted pacemakers must not work with the machine or
move in their immediate vicinity! There is a risk of the stimulator
malfunctioning!
5. Persons in the vicinity of the welding site must also be informed of the
danger and provided with protective equipment.
6. When welding especially in small spaces, it is necessary to ensure a
sufficient supply of fresh air, as welding produces harmful emissions.
7. Do not perform welding work on gas, oil, fuel, etc. Tanks (even empty ones)
as there is a risk of explosion.
8. Special regulations apply in potentially explosive atmospheres.
9. Stop welding immediately if the power cord is damaged. Do not touch this
cable. Unplug it.
10. In areas with an increased risk of electric shock. Only machines marked
with the symbol can be used
.
11. Welded joints that are subject to high stress must meet special safety
requirements. These are mainly rails, pressure vessels, etc. These joints
may only be made by qualified trained welders with the necessary
authorization.
SAFETY REGULATIONS
1. Before starting work with the welding machine, it is necessary to get
acquainted with the provisions in ČSN 050601 – Safety provisions for metal
welding and the standard ČSN 050630 – Safety provisions for arc welding
of metals.
2. The CO2 bottle of mixed gases must be handled in accordance with the
regulations for working with pressure vessels contained in ČSN 078305.
3. The welder must use protective equipment.
4. When handling the machine with a lifting device, hook the machine on all
crane eyes. Other mounting is not permitted!
5. Disconnect the device from the mains before carrying out any work on the
electrical system, removing the cover or cleaning it.
