For welding and similar processes: Due to the protective level of the apron (Class 2 A1+A2), it is recommended to be used together with the protective clothing SDL-20 and SKL-10 for manual processes where a larger quantity of metal droplets is generated, thus requiring increased protection (e.g., manual arc welding with alkaline or cellulose electrodes, carbon dioxide arc welding, or arc welding with a consumable electrode using mixed shielding gas, plasma cutting, arc planing, oxygen cutting, thermal spraying) and under working conditions that demand higher protection (e.g., welding/cutting in confined spaces, head-to-head, or similar restricted body positions).
