Zvakajairwa welding mask:
Ordinary welding mask chimedu chehelmet shell ine girazi dema. Kazhinji girazi dema rinongova girazi renguva dzose rine mumvuri 8, kana welding unoshandisa girazi dema uye pakukuya vamwe vanhu vanotsiva girazi rekumashure kune girazi rakajeka kuti vaone zvakajeka. Iyo ngowani yewelding inowanzoda nzvimbo yakafara yekuona, kutaridzika kwepamusoro, kutakurika, kufefetedza, kupfeka zvakanaka, kusadonha kwemhepo, kusimba uye kusimba. Rakajairika girazi dema rinogona kudzivirira kubva kuchiedza chakasimba panguva yewelding, hazvibviri kuvharira mwenje infrared uye ultraviolet mwaranzi izvo zvinonyanya kukuvadza maziso panguva yewelding, izvo zvinozoita kuti electro-optic ophthalmia. Uye zvakare, nekuda kwehunhu hwegirazi dema, iyo yekushongedza nzvimbo haigone kuoneka zvakajeka panguva yekutanga arc uye iwe unogona chete weld zvinoenderana neruzivo rwako uye manzwiro. Nokudaro zvinotungamirira kune mamwe matambudziko akachengeteka.
Auto darkening welding helmet:
Auto kusviba welding ngowani inonzi zvakare otomatiki welding mask kana otomatiki welding ngowani. Kunyanya kunosanganisira Auto Rima Sefa uye ngowani shell. Auto kusviba welding sefa ndeye yakagadziridzwa yepamusoro-tech yekudzivirira basa chinyorwa, inoshandisa iyo photoelectric musimboti, uye kana arc yemagetsi welding yagadzirwa, ma sensors anobata masaini uye ipapo iyo LCD inoshanduka kubva kupenya kuenda kurima nekumhanya kwakanyanya 1/ 2500ms. Rima rinogona kugadziriswa pakati peDIN4-8 neDIN9-13 maererano nemamiriro akasiyana-siyana akadai sekucheka uye welding uye kugaya. Kumberi kweLCD kwakashongedzerwa negirazi rakavharidzirwa, iro rinogadzira inoshanda UV / IR sefa musanganiswa ine multilayer LCD uye polarizer. Ita kuti ultraviolet mwenje uye infrared mwenje zvisafambike zvachose. Nekudaro kudzivirira zvinobudirira maziso evacheki kubva mukukuvadzwa kwemirairo ye ultraviolet uye infrared mwaranzi. Paunenge uchida kumisa welding uye wotanga kukuya, ingoiisa kune grind mode uye ipapo iwe unogona kuona zvakajeka uye inogonawo kudzivirira maziso ako zvakanaka.
