Precautions
①Checkallpartsofthemaskforobviousscars,cracks,scratches,orabnormalappearance.
②Checkallpartsofthemasktoseeifthescrewsarelooseorfallapart.
③Becausethereisagapbetweentheprotectivemaskandtheface,theprotectiveglassescanalsobeusedwiththeprotectivemask.
④Whenworkingwiththeweldingmask,inordertopreventthesparksfromhurtingthebody,donotstopusingitinthemiddle.
⑤Whenusingfire-proofandheat-proofmasks,confirmwhetherthereisharmfullight.Ifso,useitwithlight-proofglasses.
