LAHTI PRO PROLINE MEGA TRYTON VULCAN Technical informations PAGE WWW.PROFIX.COM.PL 188 FACE SHIELDS MARKING OF FACE SHIELDS WELD SHIELDS Face shields are personal protective equipment intended for protection of eye and face against the effects of intense thermal radiation, present mainly during a heat treatment of metals and glass, hot metal splash and may also protect against splashes of molten metals. Shields are mounted directly on the head of a user or a protective helmet. Protection screens of such type of shields are usually made of a volume-coloured polycarbonate or polycarbonate with added layers reflect - ing thermal radiation, used wherever thermal radiation is particularly high. Welding helmets and weld shields are used during electric arc welding, electroerosion, oxy-fuel and plasma arc cutting. Welding helmets may be equipped with a single welding filter or two welding filters, one of which is a filter used only for obser - vation, and the other a proper darker filter used for observation of a welding process. Welding helmets with automatic welding filters are also used. Such filters dim the field of vision automatically during e.g. electric or plasma arc observation, and after its disappearance (in weld cooling rate) they automatically brighten the field of vision. Welding helmets may be additionally equipped with a ventilation system, supplying air from the back of the welder’s head, which significantly re - duces the amount of the inhaled welding fumes (dusts and gases) produced during welding or may be equipped with handles enabling assembly of filtering devices with forced air flow. Weld shield is designed for eye protection, as well as the entire face and neck of a welder. The basic limitation of the use of a weld shield is the necessity of holding in hand during welding, which significantly reduces the freedom of movements of an employee, e.g. making it impossible to hold a welded object . • identification mark of a manu - facturer, model marking • standard no. • optical class • mechanical resistance • protection against particles with high speed in extreme temperatures (optional) • protection against liquid splashes • CE mark EN 166 1 B T 3 XX PROCESS CURRENT [A] 1.5 6 10 15 30 40 60 70 100 125 150 175 200 225 250 300 350 400 450 500 600 Covered electrodes 8 9 10 11 12 13 14 MAG 8 9 10 11 12 13 14 TIG 8 9 10 11 12 13 MIG heavy metals 9 10 11 12 13 14 MIG light alloys 10 11 12 13 14 Electroerosion 10 11 12 13 14 15 PAC 9 10 11 12 13 PAW 4 5 6 7 8 9 10 11 12 • MIG - welding by means of a consumable electrode shielded by inert gas • MAG - welding by means of a consumable electrode shielded by active gas • TIG - welding by means of a tungsten electrode shielded by inert gas • Electroerosion - with the use of a carbon electrode and compressed air used for blowing-off molten metal • PAC – plasma arc cutting • PAW – plasma arc welding Selection of a welding filter conforming to EN169/EN175 XX EN 175 • identification mark of a manufacturer, model marking • standard no. • CE mark Internal side of the shield MARKING OF WELD SHIELDS
