keevitusmeetod | mma |
MMA 140a inverterkeevitusseade, which is based uusima generation IGBT transistoridel. uses keevitusseadmete turul läbimurdelist lahendust specially designed mikroprotsessori näol, which leads iseseisvalt entire keevitusprotsessi. loogiliste ahelate reduction and algne keevitusvoolu proovivõtumeetod not only no vähenda Device rikke määra, only Changes primarily keevitusprotsessi enda much lihtsamaks . high quality keevisõmbluse saamise lihtsust hindavad nii professionaalid and also with little kogemusega inimesed.
our tehases developed, Taiwanis manufactured mikroprotsessor is based Arm4 arhitektuuril, by using 55nm technology, which taktsagedus on 200MHz 32-bitisel kujul. allows juhtida uusima generation transistore speeds up to 70 kHz, which is peaaegu two times faster kui võrreldavates in devices. has patented lahendust keevitusparameetrite analüüsimiseks with speed aprox kakssada million korda sekundis . rules out vajaduse to install lisasüsteeme this kind funktsioonide . like kaarejõud, kleepumisvastane or kuumkäivitus. lisasüsteemide puudumine tähendab, et power muundamisprotsessis emerging häirete effect keevitamise kvaliteedile on marginaalne neither ole kasutajale noticeable.
hot start
kui electrode asetatakse welded to the material, increases welder sekundi murdosa võrra keevitusvoolu, which Changes arc süttimise much lihtsamaks. Mudelil yt-81355 is not It's functions . built-in parameetrite seadistusi. these on preconfigured turul most populaarsematele elektroodide tüübile, st rutiilelektroodidele.
arc power
reguleerib arc dynamics depending on electrode kaugusest welded elements. YT-81355-s to use multitegumtöötlus mikroprotsessor uurib keevitusparameetreid aprox kakssada million korda sekundis. analyzes mõõtetulemusi reaalajas. siis, juhtides transistore speed up to 70 tuhat korda sekundis, increases or Decreases this keevitusvoolu. all happens sekundi murdosa jooksul and their tegevuste eesmärk on saada this vooluseadistuse . best quality keevitusallikas. Mudelil yt-81355 is not It's functions . built-in parameetrite seadistusi. these on preconfigured turul most populaarsematele elektroodide tüübile, st rutiilelektroodidele.
pulgavastane
katkestab keevitusvoolu, kui electrode on lühises, which allows electrode welded material disconnect.
vrd
function Decreases tühivoolupinget aprox 60 V-lt inimesele ohutule tasemele. Vaatamata It's olulisele mõjule turvalisusele, lülitavad kasutajad It's functions often out. this kind tegude cause on problems arc löömisega, especially with little kogemusega inimestel. most inverterkeevitajaid measures väljundvoolu analoogandurite abil, which ultimately prolongs reageerimisaega and this tulenevalt raskendab arc süütamist. yt-81355 mikroprotsessor teeb it teisiti. this Forms keevitusvooluahelas lainekuju sagedusega aprox 200 MHz. reaalajas uurib this lainekuju deformatsioone, which varieeruvad depending on this keevitusetapist. hetk, mil electrode puudutab welded elements, tuvastatakse sekundi murdosa after, then lülitatakse vrd function out and at the same time begins tööle kuumkäivitus. arc süttimise probleemi no esine. Mudelil yt-81355 on vrd-function permanently allowed.
protection overload and overheating eest (fan nõudmisel)
yt-81355 mikroprotsessor checks kriitiliste components temperature reaalajas. depending on temperature leads this first fan speed, but kui temperature rises liiga high, Decreases mikroprotsessor smoothly väljundvoolu, which allows elektroodide põletamist or keevisõmbluse kontrollitud completion. Enamikus turul olevatest keevitusmasinatest tähendab overheating hetk keevitusvoolu kohest väljalülitamist, which because of on often needed welded elements mehaanilisi parandusi teha. it probleemi yt-81355 puhul no esine
