Various factors affect the correct choice of appropriate protection. It is not only greatly determined by the welding method and amperage. The workplace conditions, in terms of gas, smoke and particle levels and the average duration of welding also need taking into account. Welding experts who spend several hours a day welding and use a range of different welding methods may for example have much greater demands of their protection equipment than people who only weld occasionally or rarely.
You can use the table below to see which product range is most suitable for your ventilation, average duration of welding and space requirements.
Once you have established the appropriate product range, consult the table on page 11 for the shade level recommended by the EN 169 standard for your amperage and application. The various bars indicate which helmet may be appropriate. You can then evaluate functions such as sensitivity, delay and grind in the detailed helmet descriptions on the following pages.
