SAFETY PRECAUTIONS
PERSONAL PROTECTION
1. For safety reasons, it is necessary to use welding gloves during welding.
These gloves will protect you before intervention of electric current
(open circuit voltage). It protects you against thermal radiation and splashing
drops of hot metal too. Wear sturdy isolated shoes. Do not wear open shoes,
because drops of hot metal can cause burns.
2. Do not look into the welding arc without eye and face protection. Always use
good quality welding helmet with intact protective filter.
3. The persons appearing in the vicinity of the welding must be informed of the
danger and must be equipped with protective equipment.
4. During welding, especially in small spaces, it is necessary to ensure an
adequate supply of fresh air, because during welding, harmful fumes arise.
5. In tanks of gas, oil, fuel, etc., (even empty ones) do not make welding,
because there is a chance of explosion.
6. In areas with chance of explosion special provisions are applied.
7. Welding machines that are subjected to great exertion must comply with
specific security requirements. These include the rail pressure of the vessel
etc. These connections may only be carried out by competently trained
welders with the necessary permissions.
SAFETY REGULATIONS
1. Before starting work with welding machine it is necessary to get familiar with
the provisions of the ČSN 050601 and norm ČSN 050630.
2. With a bottle of CO2 or mixed gases should be handled according to the
regulations for working with pressure vessels contained in ČSN 07 83 05 and
norm ČSN 07 85 09.
3. The welder must use protective equipment.
