Kana zvasvika kune welding, yakawandisa yechinhu chakanaka kazhinji inogona kuwedzera kusvika kumitengo isingakodzeri, inogona kuderera uye yakarasika chibereko - kunyanya kana uine yakakura kwazvo yeMIG pfuti yekushandisa kwako. Nehurombo, vanhu vazhinji vanotenda fungidziro yakajairika: yekuti unoda pfuti yeMIG yakaverengerwa kusvika padanho repamusoro raunotarisira kuchinjisa (semuenzaniso, 400-amp pfuti ye400-amp application). Icho hachisi chokwadi. Muchokwadi, pfuti yeMIG inopa yakakwira amperage kugona kupfuura yaunoda kazhinji inorema uye inogona kushomeka, ichiita kuti isasununguke kufamba uchitenderedza weld majoini. Yepamusoro amperage MIG pfuti zvakare inodhura zvakanyanya.
Kusarudza pfuti "yakawandisa" inogona kuwedzera kuneta uye kuderedza chibereko chako. Iyo yakanakira MIG pfuti inorova chiyero pakati pezvido zvekushandisa, uye saizi uye huremu hweMIG yepfuti.
Chokwadi ndechekuti, nekuti iwe unopedza nguva uchifambisa zvikamu, uchizvibata uye uchiita zvimwe pre- uye zvemashure-weld zviitiko, iwe hauwanzo weld zvakaringana kuti usvike pakakwirira basa kutenderera kweiyo MIG pfuti. Pane kudaro, kazhinji zviri nani kusarudza pfuti yakareruka, isingachinjiki inoenderana nezvido zvako. Semuyenzaniso, pfuti yeMIG yakarongerwa 300 amps inogona kazhinji weld pa400 amps zvichikwira - kwenguva shoma - uye kuita basa rakanaka.
Pfuti ratings akatsanangura
MuUnited States, National Electrical Manufacturers Association, kana NEMA, inogadza iyo MIG pfuti maitiro. MuEurope, zviyero zvakafanana ibasa reConformité Européenne kana European Conformity, inonziwo CE.
Pasi pemasangano ese ari maviri, pfuti dzeMIG dzinogashira chiyero chinoratidza tembiricha iri pamusoro apo mubato kana tambo inodziya zvisingaite. Zviyero izvi, zvisinei, hazviratidze nzvimbo iyo pfuti yeMIG inokuvadza kukuvara kana kutadza.
Musiyano mukuru uri mukutenderera kwebasa repfuti. Vagadziri vane sarudzo yekuyera pfuti dzavo pa100-, 60- kana 35-percent yebasa cycles. Nechikonzero ichocho, panogona kuve nekusiyana kwakakura kana tichienzanisa zvakasiyana zvigadzirwa zveMIG pfuti zvigadzirwa.
Duty cycle ndiyo huwandu hwearc-on nguva mukati memaminitsi gumi. Imwe MIG inogadzira pfuti inogona kuburitsa 400-amp MIG pfuti inokwanisa kuvhetemesa pa100 muzana yebasa, nepo imwe inogadzira yakafanana amperage MIG pfuti inogona kusonerera pa60 muzana yebasa chete. Mumuenzaniso uyu, pfuti yekutanga yeMIG yaizokwanisa kusungirira nguva dzose pakuzara kwemaminetsi gumi, asi iyo yekupedzisira yaizongokwanisa kusonwa kwemaminetsi matanhatu.
Usati wafunga kuti ndeupi pfuti yeMIG yekutenga, zvakakosha kuti uongorore mareshiyo ebasa rekutenderera kwechigadzirwa. Iwe unogona kazhinji kuwana ruzivo urwu muzvinyorwa zvechigadzirwa kana pawebhusaiti yemugadziri.
Unoshanda sei?
Zvichienderana netsananguro yepfuti iri pamusoro, zvakakoshawo kuti iwe ufunge nezvehurefu hwenguva yaunoshandisa uchikweshera usati waita yako MIG pfuti sarudzo. Tarisa uone kuti inguvai yaunonyatso shandisa welding mukati mekufamba kwemaminetsi gumi. Unogona kushamisika kuona kuti avhareji arc-panguva kazhinji isingasviki maminetsi mashanu.
Ramba uchifunga kuti welding ine MIG pfuti yakarongerwa 300 amps yaizopfuura yayo yakayerwa kugona kana iwe uchizoishandisa pa400 amps uye zana-muzana rebasa kutenderera. Nekudaro, kana iwe wakashandisa iyo pfuti imwe chete kuchinjisa pa400 amps uye 50-muzana-muzana basa kutenderera, inofanira kushanda zvakanaka. Saizvozvo, dai wanga uine application yaida welding simbi yakakora kwazvo pamitoro yakakwira yazvino (kunyangwe 500 amps kana kupfuura) kwenguva pfupi, unogona kushandisa pfuti yakayerwa pamaamps mazana matatu chete.
Semutemo wakajairwa, pfuti yeMIG inopisa zvisingaite kana ichidarika chiyero chetembiricha yekutenderera kwayo. Kana iwe ukazviwana iwe welding kwenguva yakareba nguva nenguva, iwe unofanirwa kufunga nezve welding pane yakaderera duty cycle kana kushandura kune yakakwira yakayerwa pfuti. Kupfuura tembiricha yeMIG yepfuti kunogona kutungamira kune isina simba kubatanidza uye tambo dzemagetsi, uye kupfupisa hupenyu hwayo hwekushanda.
Kunzwisisa kukanganisa kwekupisa
Kune marudzi maviri ekupisa anokanganisa mubato uye tembiricha yetambo paMIG pfuti uye zvakare huwandu hwenguva yaunokwanisa kubatanidza nayo: kupisa kunopenya kubva kuarc uye kupisa kunodzivirira kubva kune tambo. Ose ari maviri emhando dzekupisa anokonzeresa mune iyo chiyero cheMIG pfuti yaunofanirwa kusarudza.
Radiant Heat
Radiant heat (Radiant heat) kupisa kunotaridza kudzokera kumubato kubva kune welding arc ne base metal. Ndiyo inokonzera kupisa kwakawanda kunosangana neMIG pfuti mubato. Pane zvinhu zvakati kuti zvinoikanganisa, kusanganisira zvinhu zviri kugadzirwa. Kana iwe ukashongedza aluminium kana simbi isina tsvina, semuenzaniso, uchaona kuti inoratidza kupisa kwakawanda kupfuura simbi yakapfava.
Iyo yekudzivirira gasi musanganiswa iwe yaunoshandisa, pamwe neye welding yekufambisa maitiro, inogona zvakare kukanganisa kupisa kunopenya. Semuenzaniso, argon inogadzira arc inopisa kupfuura CO2 yakachena, zvichiita kuti pfuti yeMIG ishandise argon inodzivirira gasi musanganiswa kuti isvike patembiricha yayo yakadzikira pane yakaderera kupfuura kana welding ne CO2 yakachena. Kana iwe ukashandisa yekupfapfaidza yekufambisa maitiro, unogona zvakare kuona kuti yako welding application inogadzira kupisa kwakawanda. Kuita uku kunoda 85 muzana kana yakapfuma argon inodzivirira gasi musanganiswa, pamwe chete netambo refu kunze uye kureba kwearc, izvo zviri zviviri zvinowedzera voltage mukushandisa uye tembiricha yese. Mhedzisiro ndeye, zvakare, kupisa kwakanyanya.
Kushandisa iyo yakareba MIG pfuti mutsipa kunogona kubatsira kuderedza kukanganiswa kwekupisa kunopenya pamubato nekuiisa mberi kubva kuarc nekuichengeta ichitonhorera. Izvo zvinoshandiswa zvaunoshandisa zvinogona kukanganisa kuwanda kwekupisa uko mutsipa unobata. Chenjerera kuti uwane zvinobatika zvinobatana zvakasimba uye zvine huwandu hwakanaka, sezvo izvi zvinotora kupisa zviri nani uye zvinogona kubatsira kudzivirira mutsipa kubva pakutakura kupisa kwakawanda kune mubato.
Resistive Heat
Pamusoro pekupisa kunopenya, unogona kusangana nekupisa kwekudzivirira mune yako welding application. Resistive kupisa kunoitika nenzira yekudzivirira kwemagetsi mukati mewelding tambo uye inokonzera kuzhinji kwekupisa mutambo. Izvo zvinoitika kana magetsi anogadzirwa nemagetsi asingakwanisi kuyerera kuburikidza netambo uye tambo dzekubatanidza. Simba remagetsi "rakatsigirwa" rinorasika sekupisa. Kuva netambo yakakura zvakakwana kunogona kuderedza kupisa kwekudzivirira; zvisinei, haigoni kuibvisa zvachose. Tambo yakakura zvakakwana kubvisa zvachose kuramba ingave yakanyanya kurema uye isingaite kufambisa.
Sezvo pfuti yakanyoroveswa nemhepo yeMIG inowedzera mu amperage, saizi yetambo, zvinongedzo uye zvibatiso zvinowedzerawo. Naizvozvo, pfuti yeMIG ine yakakwira chiyero chepamusoro inenge inogara ine hukuru hukuru. Kana iwe uri welder apo neapo, kuti uremu uye saizi kuwedzera zvingasakunetsa iwe; zvisinei, kana iwe weld zuva rose, mazuva ese, zviri nani kuwana yakareruka uye diki MIG pfuti inokodzera application yako. Mune zvimwe zviitiko, izvo zvinogona kureva kuchinjika kumvura-yakatonhorera MIG pfuti, iyo idiki uye yakareruka, asi inogona kupa yakafanana welding kugona.
Kusarudza pakati pemhepo-nemvura-yakatonhorera
Kushandisa pfuti yeMIG yakareruka kunogona kazhinji kuvandudza kugadzirwa sezvo zviri nyore kufambisa kwenguva yakareba. Zviduku zveMIG pfuti zvinogonawo kuderedza kukanganisa kwako kudzokorora kukuvara kwekufamba, senge carpal tunnel syndrome.
Pfungwa dzekupedzisira kuti ugare wakasununguka
Paunenge uchisarudza yako MIG pfuti, yeuka kuti hazvisi zvese zvigadzirwa zvakagadzirwa zvakaenzana. Pfuti mbiri dzeMIG dzakapihwa 300 amps dzinogona kusiyana zvakanyanya maererano nehukuru hwadzo uye huremu. Tora nguva yekutsvaga zvaungasarudza. Zvakare, tsvaga zvinhu zvakaita semubato unopinza mhepo unobvumira mweya kuyerera nemauri uye woita kuti urambe uchitonhora. Zvinhu zvakadai zvinowanzobvumira pfuti kuti ionekwe kune imwe nzvimbo yepamusoro pasina kuwedzera chero saizi kana uremu. Chekupedzisira, ongorora nguva yaunoshandisa welding, maitirwo nekudzivirira gasi raunoshandisa, uye zvinhu zvauri kuveza. Kuita izvi kunogona kukubatsira kuti usarudze pfuti inorova yakaringana pakati pekunyaradza uye kugona.
