Safety & health

Hazardous substances, radiation, gases, fire risk, and radioactive grinding dust — the protection that keeps you healthy while welding.

Welding Fumes & Hazardous Substances

When welding, fine particles and gases are produced — depending on the material and process, a dangerous cocktail. From metal fume fever with galvanized steel to chromium(VI) with stainless steel: if you know the hazardous substances, you can protect your lungs properly.

UV/IR Radiation & Eye Protection

The arc is one of the most intense radiation sources in the workshop: UV, infrared, and glaring light all at once. An unprotected glance leads to painful arc eye, and the skin burns like sunburn. Proper protection is a must — for you and for everyone nearby.

Gases & Cylinder Storage

Acetylene is highly explosive, oxygen promotes combustion, shielding gases asphyxiate silently. Compressed gas cylinders aren't storage shelves — mishandle them in transport, storage, or connection, and you risk more than a bad weld.

Fire & Explosion Protection

Welding is fire work — sparks fly for meters, metal conducts heat through entire components, and residual vapors in an empty drum can explode. Knowing the fire hazards and preparing the environment prevents most fires before a spark falls.

Thorium Electrodes & Radioactive Dust

Red (2%) and orange (4%) tungsten electrodes are doped with thorium — they have excellent service life but are radioactive and toxic. Grinding produces radioactive dust. Cerium and lanthanum electrodes do the same job without the danger.
