Xa kuziwa kwi-welding, into eninzi kakhulu into enhle inokuthi idibanise kwiindleko ezingadingekile, ixesha lokuphumla elinokwenzeka kunye nokulahlekelwa kwemveliso - ngakumbi ukuba unompu omkhulu we-MIG kwisicelo sakho. Ngelishwa, abantu abaninzi bakholelwa ingcamango ephosakeleyo eqhelekileyo: ukuba ufuna umpu we-MIG onikwe umlinganiselo ophezulu olindele ukuweld (umzekelo, umpu we-400-amp kwisicelo se-400-amp). Asiyonyaniso leyo. Ngapha koko, umpu we-MIG obonelela ngomthamo ophezulu we-amperage kunokuba ufuna ngokwesiqhelo unobunzima obungaphezulu kwaye usenokuba bhetyebhetye kancinci, usenza ukuba kube lula ukuzulazula malunga ne-weld joints. Imipu ye-MIG enomgangatho ophezulu nayo ixabisa ngaphezulu.
Ukukhetha "kakhulu" umpu kunokunyusa ukudinwa kunye nokunciphisa imveliso yakho. Umpu ofanelekileyo weMIG ubetha ibhalansi phakathi kweemfuno zesicelo, kunye nobukhulu bompu weMIG kunye nobunzima.
Inyaniso kukuba, ngenxa yokuba uchitha ixesha uhambisa iinxalenye, uzicoca kwaye wenze ezinye izinto zangaphambili kunye nezasemva kwe-weld, awufane udibanise ngokuqhubekayo ngokwaneleyo ukufikelela kumjikelo omkhulu womsebenzi walo mpu we-MIG. Endaweni yoko, kudla ngokuba ngcono ukukhetha owona mpu ukhaphukhaphu, ubhetyebhetye kakhulu ohlangabezana neemfuno zakho. Ngokomzekelo, umpu we-MIG olinganiswe kwii-amps ezingama-300 unokutshiza kwii-amps ezingama-400 nangaphezulu - ixesha elincinci - kwaye wenze umsebenzi olungileyo.
Amanqaku ompu acacisiwe
EUnited States, i-National Electrical Manufacturers Association, okanye i-NEMA, iseka i-MIG gun rating criteria. EYurophu, imigangatho efanayo luxanduva lweConformité Européenne okanye iEuropean Conformity, ekwabizwa ngokuba yiCE.
Ngaphantsi kwee-arhente zombini, imipu ye-MIG ifumana umlinganiselo obonisa amaqondo obushushu angaphezulu apho isibambo okanye intambo ifudumala ngokungathandekiyo. Ezi zilinganiso, nangona kunjalo, azichongi indawo apho umpu we-MIG ubeka engozini umonakalo okanye ukusilela.
Umahluko omkhulu ulele kumjikelo womsebenzi wompu. Abavelisi banokukhetha ukulinganisa imipu yabo kwi-100-, 60- okanye i-35-percent duty cycle. Ngeso sizathu, kunokubakho umahluko omkhulu xa kuthelekiswa iimveliso ezahlukeneyo zomenzi wemipu yeMIG.
Umjikelo womsebenzi sisixa sexesha le-arc-on kwithuba lemizuzu eli-10. Omnye umenzi wompu we-MIG unokuvelisa umpu we-MIG we-400-amp okwaziyo ukuwelda kumjikelo we-100 lepesenti yomsebenzi, ngelixa omnye uvelisa umpu ofanayo we-MIG onokuthi udibanise kumjikelo we-60 ekhulwini kuphela. Kulo mzekelo, umpu wokuqala we-MIG uya kukwazi ukuwelda ngokuqhubekayo kwi-amperage epheleleyo kangangemizuzu eli-10, ngelixa lo mva uya kukwazi ukuwelda imizuzu emi-6.
Ngaphambi kokuthatha isigqibo malunga nokuba yeyiphi i-MIG gun onokuyithenga, kubalulekile ukuphonononga ulungelelwaniso lomjikelo womsebenzi wemveliso. Unokufumana olu lwazi kuncwadi lwemveliso okanye kwiwebhusayithi yomenzi.
Usebenza njani?
Ngokusekwe kwingcaciso yokukala kompu apha ngasentla, kukwabalulekile ukuba ucinge ngobude bexesha olichithayo ukuwelda phambi kokuba wenze ukhetho lwakho lompu weMIG. Jonga ukuba lingakanani ixesha olichitha ekudibaniseni kwisithuba semizuzu eli-10. Unokumangaliswa kukufumanisa ukuba ixesha eliphakathi kwe-arc lihlala lingaphantsi kwemizuzu emi-5.
Gcina ukhumbule ukuba i-welding nge-MIG gun elinganiswe kwi-300 amps iya kudlula umthamo wayo olinganisiweyo ukuba uya kuwusebenzisa kuma-amps angama-400 kunye neepesenti ze-100 zomjikelezo womsebenzi. Nangona kunjalo, ukuba usebenzise umpu ofanayo ukuze udibanise kwi-amps ezingama-400 kunye nomjikelo we-50-pesenti yomsebenzi, kufuneka usebenze kakuhle. Ngokufanayo, ukuba unesicelo esifuna ukuwelda isinyithi esishinyene kakhulu kwimithwalo yangoku ephezulu (nokuba ngama-500 ee-amps okanye ngaphezulu) ixesha elifutshane kakhulu, usenokusebenzisa umpu olinganiswe ngama-amps angama-300 kuphela.
Njengomgaqo jikelele, umpu we-MIG uba shushu ngokungathandekiyo xa udlula umlinganiselo wobushushu opheleleyo womjikelo wawo. Ukuba uzifumana u-welding ixesha elide rhoqo, kuya kufuneka ucinge ukuba udibanisa i-welding kumjikelo ophantsi womsebenzi okanye utshintshele kumpu onereyithi ephezulu. Ukodlula umthamo weqondo lobushushu lompu we-MIG kunokukhokelela kuqhagamshelo olubuthathaka kunye neentambo zamandla, kunye nokunciphisa ubomi bayo bokusebenza.
Ukuqonda impembelelo yobushushu
Kukho iintlobo ezimbini zobushushu obuchaphazela isiphatho kunye nobushushu bentambo kwi-MIG gun kunye nexesha onokuthi udibanise nalo: ubushushu obukhanyayo obuvela kwi-arc kunye nobushushu obuchasayo obuvela kwintambo. Zombini ezi ntlobo zobushushu zenza ukuba loluphi ukalisho lwe-MIG omele ukhethe.
Ubushushu obukhazimlayo
Ubushushu obukhazimlayo bubushushu obubonakalisa umva kwi-handle ukusuka kwi-arc ye-welding kunye nesiseko sesinyithi. Inoxanduva lobuninzi bobushushu obufunyenwe sisiphatho sompu we-MIG. Zininzi izinto ezichaphazelayo, kubandakanywa izinto ezidityanisiweyo. Ukuba udibanisa i-aluminiyam okanye insimbi engenasici, umzekelo, uya kufumanisa ukuba ibonisa ubushushu obuninzi kunentsimbi ethambileyo.
Umxube wegesi okhuselayo owusebenzisayo, kunye nenkqubo yokudlulisa i-welding, inokuchaphazela nobushushu obukhanyayo. Ngokomzekelo, i-argon idala i-arc eshushu kune-CO2 ecocekileyo, ebangela umpu we-MIG usebenzisa i-argon yokukhusela umxube wegesi ukuze ufikelele kwiqondo lokushisa elilinganisiweyo kwi-amperage ephantsi kunokuba xa udibanisa nge-CO2 ecocekileyo. Ukuba usebenzisa inkqubo yokudlulisa isitshizi, usenokufumanisa ukuba isicelo sakho se-welding sivelisa ubushushu obuninzi. Le nkqubo idinga i-85 yepesenti okanye i-argon ecebileyo yokukhusela umxube wegesi, kunye nocingo olude oluphuma ngaphandle kunye nobude be-arc, zombini ezo zinyusa i-voltage kwisicelo kunye nobushushu obupheleleyo. Isiphumo kukuba, kwakhona, ubushushu obuqaqambileyo.
Ukusebenzisa intamo ende ye-MIG yompu kunokunceda ukunciphisa impembelelo yobushushu obukhazimlayo kwisibambo ngokuyibeka phambili ukusuka kwi-arc kwaye uyigcine ipholile. Izinto ezisetyenziswayo ozisebenzisayo zinokuchaphazela ubungakanani bobushushu obufunxa intamo. Qaphela ukuba ufumane izinto ezisetyenziswayo ezidibanisa ngokuqinileyo kwaye zibe nobunzima obuhle, njengoko ezi zifunxa ubushushu ngcono kwaye zinokunceda ukuthintela intamo ekuthwaleni ubushushu obuninzi kwisibambo.
Ubushushu obuxhathisayo
Ukongeza kubushushu obukhanyayo, unokuhlangabezana nobushushu obuxhathisayo kwisicelo sakho se-welding. Ukushisa okuxhathisayo kwenzeka ngendlela yokumelana nombane ngaphakathi kwentambo ye-welding kwaye inoxanduva lobuninzi bobushushu kwintambo. Kwenzeka xa umbane owenziwe ngumthombo wamandla awukwazi ukuhamba ngentambo kunye nokudibanisa intambo. Amandla ombane "axhaswayo" alahlekile njengobushushu. Ukuba nentambo yobungakanani ngokwaneleyo kunokunciphisa ubushushu obuxhathisayo; nangona kunjalo, ayinakukuphelisa ngokupheleleyo. Intambo enkulu ngokwaneleyo ukuphelisa ngokupheleleyo ukuxhathisa iya kuba nzima kakhulu kwaye ingabi namandla ukuyiqhuba.
Njengoko umpu we-MIG opholileyo womoya ukhula kwi-amperage, ubukhulu bekhebula, ukudibanisa kunye nezibambo nazo zanda. Ke ngoko, umpu weMIG onereyithi ephezulu yomthamo phantse uhlala unobunzima obukhulu. Ukuba ungumtshisi we-welder ngamaxesha, ubunzima kunye nokunyuka kobukhulu akunakukukhathaza; nangona kunjalo, ukuba udibanisa imini yonke, yonke imihla, kungcono ukufumana umpu we-MIG okhanyayo kunye omncinci olungele isicelo sakho. Kwezinye iimeko, oko kunokuthetha ukutshintshela kumpu we-MIG opholile ngamanzi, omncinci kwaye ulula, kodwa unokubonelela ngomthamo ofanayo we-welding.
Ukugqiba phakathi kokupholisa umoya kunye namanzi
Ukusebenzisa umpu we-MIG olula kunokuphucula imveliso kuba kulula ukuwulawula ixesha elide. Izibhamu ezincinci ze-MIG zinokunciphisa ukubakho kwakho ukulimala okuphindaphindiweyo, njenge-carpal tunnel syndrome.
Iingcamango zokugqibela zokukugcina ukhululekile
Xa ukhetha umpu wakho weMIG, khumbula ukuba ayizizo zonke iimveliso ezenziwe ngokulinganayo. Izibhamu ezimbini ze-MIG ezilinganiswe kwii-amps ze-300 zinokuhluka ngokubanzi malunga nobukhulu bazo kunye nobunzima. Thatha ixesha lokuphanda iinketho zakho. Kwakhona, khangela izinto ezifana nesiphatho esingena umoya esivumela umoya ukuba udlule kuso kwaye siwugcine upholile. Iimpawu ezinjalo zihlala zivumela umpu ukuba ulinganiswe kumthamo ophezulu ngaphandle kokongeza nayiphi na isayizi okanye ubunzima. Okokugqibela, hlola ixesha olichitha uwelda, inkqubo kunye negesi yokukhusela oyisebenzisayo, kunye nezixhobo ozidibanisayo. Ukwenza njalo kunokukunceda ukhethe umpu obetha ulungelelwano olufanelekileyo phakathi kokuthuthuzela kunye nomthamo.
