Me tika ki te pānui i te tohutohu i runga i te whakamahi o te mīhini fehokotaki'anga me mahi katoa o te raraunga tohutoro reira.

hiko

I mua i tamata koe ki te ako i roto i te mahi me pehea ki te Weld whakarewa, me hanga e koe tino e te tawhā o te whatunga hiko, powered nei i te mīhini fehokotaki'anga, e tano ki ona whakaritenga. Kore, e taea te pakaru atu taputapu hiko hono ki te whatunga, koutou e kore anake, engari ano hoki i roto i nga whenua e tata ana. Ko mīhini hiko fehokotaki'anga rawa pono, e nui pā te aroaro o mains ongo ngaohiko i roto i te tīmatanga fehokotaki'anga me nui haere te kohi o te nāianei hiko ina titi te kawehiko e i roto i te Weld tenei. I tua atu, kia tuu te reira i te mīhini fehokotaki'anga kore kia taea hinga reira, hoko ano kino ranei ki te iwi tata ahanoa ranei i roto i te mahi. Waea hono ki te kōwae me whai mātao tika, i tika ai. ka waiho taea kino.

Ko te tukanga o te faaineineraa no te mahi

Me pēhea te ki te tunu i te whakarewa? Me hurihia iho te wahi ki te kia paiherea ki te whakarewa, he reira maroke. mahi rāhuitia mahi fehokotaki'anga i paki, ua me te rangi i te pāmahana iti. e kore kia whakaaetia ki te tiki welder mākū me electrodes.

Me pēhea te ki te Weld whakarewa e hiko?

kawea fehokotaki'anga i roto i te ngaohiko tamau tauutuutu ranei. welders hiko fehokotaki'anga whakarato AC ngaohiko.

A, no te kakano ia ki nāianei hāngai e rua ngā kōwhiringa mō te tūhono i te mīhini fehokotaki'anga. A, no te tūhono ki te taimaha me me tango ki te kawehiko (i huaina tenei ko te wehenga tawhiti whakamua) he nui atu i te whakarewa te wera, hanga hohonu, me te kuiti rohe rewa. he whakakā taua whakamahia i roto i te fehokotaki'anga o whakarewa matotoru, me te arata'i ki te whakamahi economical o electrodes. A, no te tahuri i runga i te ritenga atu (wehenga whakamuri) ko atu kaha wera, ka pau whiwhi whanui, me te pāpaku rohe rewa hohoro kawehiko. Na reira, whakamahia te wehenga tawhiti whakamuri te anake ka kakano ia pepa angiangi o te whakarewa.

āhuatanga motuhake o te inverters

Me pēhea te ki te tunu i te whakarewa inverter? mīhini Inverter fehokotaki'anga tahuri AC supply mana arumoni ngaohiko ki te raupapa pini o te auau teitei a ka hanga he ngaohiko DC nāianei. Ngā mihi ki te ara iahiko hiko e ite faafariuraa raraunga, te inverter kua he mana iti i runga i te mains supply i roto i te mahi, kua he whakatikatika pai o te ngaohiko whakaputa, āhuatanga e te taimaha iti me te rahi. Ko te kounga o te hua Weld e kore e tukua inverter ki ētahi atu taputapu rite. Na reira, kua riro inverters fehokotaki'anga i roto i nga tau tata nei, ina kua heke te utu o taua whakaaro, he mea tino whānui. Ko te painga o tenei pūrere ko te tapatahi whanaunga o tona whakamahi i roto i te fehokotaki'anga.

Me pēhea te ki te whiriwhiri inverter

He tawhā nui ko te wā o te puna mana inverter kawenga (MF). Tenei uara, e faaite i te tōtika o te inverter, whakaatu ana te hononga o te wa fehokotaki'anga ki wa tāhuna. e kore e mahi tonu ngā pūrere whare. Me ratou ki te whakamatao iho ia wā. Ko te kupu, 30% o te uara PV o te inverter tikanga e i muri i nga 3 meneti whai koe ki te Weld i te whanga 7-miniti mo ki te pūtake whakamatao iho. A, no te tamata koe ki te haere tonu i waho arumanga taea tahu i te kōwae. mahi ranei tiaki, a ka tahuri te reira atu. Na reira, me whiriwhiri te inverter ki MF iti rawa 60%, me te nāianei mōrahi o te iti rawa 140 - 160 A.

Getting Started ki te inverter

Ki te riro wheako i roto i te āhua o ki te tunu tika inverter whakarewa, e tūtohu ana ki te mahi ki te whakarewa i te iti rawa 2-3 mm matotoru, me te 3 mm whakamahia rite te electrodes. Electrodes pai ki te hoko mea hou. Old, Matiu, tono i etahi, e pea ki te kia me te haukū me te kāore mō te whakamahi.

Me pēhea te ki te tunu i te whakarewa? Ki te he to koutou wheako tuatahi tenei, i te tuatahi tamata reira ki te hanga i te tui i runga i te mata o tetahi wahi o whakarewa i waho kakano ia te reira ki tetahi atu wahi.

A feruri i te raupapa o te mahi.

Tuatahi, he mea e tika ana ki te hono i te taata tei mau ki te kawehiko, me te taura whenua ki te workpiece fehokotaki'anga mā te whakamahi i te terminals. i te tahi atu pito o te waea ki te kia hono ki te putanga inverter i roto i te wehenga tawhiti noa.

Tuarua, he mea e tika ana ki te tahuri i runga i te kōwae, me te ki te whakaturia ona tawhā putanga i roto i runga i te kupu tohutohu i runga i te matotoru o te rauemi ki te kia paiherea me te kawehiko o te rahi tīpakohia rānei.

whakarewa fehokotaki'anga tikanga whakarato e hoki te para i te whakarewa ki te pāmahana e hiahiatia ana ki te whiwhi i te Weld kounga he tika ki te tango i matotoru tika o te rauemi kawehiko. Ko te nui o te whakamutunga, te nui te apa whakarewa taea whakamahana ake a me te ake nāianei whakaturia i roto i te ara iahiko inverter mō arcing. I te wa ano, pau te teitei te nāianei, te tere te whakarewa rewa me te kawehiko te tere. Hoki te kahu whakarewa angiangi ki te rua o nāianei, me te nui tiketike e maha i hanga kawehiko, tahu-i roto i rauemi. I nāianei iti rawa kore e puta ranei pewa hiko, rānei, ka puta i te reira, huri i te reira i roto i he tui o hapa, na ka karanga neprogar.

Ko te mea tuatoru e utu koe whakarongo - ko te hanganga o te pewa hiko tenei. Hoki tenei e hiahia ana tatou ki te patu i te matamata kawehiko i roto i te wahi, e ko te ki kia paiherea, ka rite ki te kēmu o te pouaka, i waho tango i te matamata kawehiko i te whakarewa. I roto i te kaupapa o te pewa i hanga e te wahi whero i runga i te whakarewa. Otiia e kore e ko te whakarewa whakarewa tenei, me rere te hanga e anake ki runga ki ngohe i te puehu o te takotoranga kawehiko. Me tatari i pupuri i te mutunga o te kawehiko i te tawhiti 1-4 mm o i te mata o te whakarewa, rite te roa rite kore te whakarewa o te pewa e whakamahana ake ki te hanganga o pera-ka karanga fehokotaki'anga pati - pata o whakarewa whakarewa, āhuatanga e te tae karaka kanapa, me te wiri o te rere o nāianei.

Fourthly, he mea e tika ana ki te hūnuku ki te tui e mahi e tetahi ki te e rua mitamano kawehiko mutunga, pupuri ano reira i te tawhiti i whakaritea i te whakarewa. Ano, tatari mo te hanganga o pata, a na i runga i, neke haere te Weld whakamana. I te papa whakarewa whakapā kawehiko ahau te hanga he taiawhio poto, riro te pewa, mono inverter nāianei. Na reira ko te reira e tika ana ki te ngana ki te mau tonu i te tawhiti tonu i waenganui i te matamata kawehiko me te mata o te whakarewa, ka te kawehiko Weld āta tata taua rite tona parariraa. Engari, e kore te tahuna te kawehiko ka rewa, te whakarewa i roto i te poka Weld i hanga te nuinga o te matua whakarewa o te kawehiko. mata kawehiko Paura-pani, hanga he rere, me te ngohe i te haurehu ārai hāora i te rangi ambient ki te whakarewa Weld me hāora, me te āwhina i te tukanga o te hanga-kounga teitei Weld.

I roto i tūtohutia te tukanga fehokotaki'anga te ki te pupuri i te kawehiko i te koki o e pā ana ki te 30 nga nekehanga i hāngai ki te workpiece i roto i te tikanga ki te hanga i te poka wai Weld kiato, me te wāhi Weld i pai taea e koe te kite. Ko te atu hehema te kawehiko ki te workpiece i roto i fehokotaki'anga, te elongated atu i roto i te huarahi i te ritenga e whakapoke i te papa whakarewa wera me te hanganga o te tōhihi Weld i te amperage kotahi. tutuki te rewa wahi Whāiti o whakarewa te i te tūnga hāngai ki te mata o te kawehiko whakarewa. Otiia i roto i tenei take welder kitea uaua mo te tukanga fehokotaki'anga. Na reira, kei te whakamahia anake tenei āhuatanga ina kakano ia i roto i ngā wāhi herea.

Me pēhea te ki te Weld inverter whakarewa?

Ka whakangungua i roto i te raveraa i te Weld ohie i runga i te mata e taea timata ki te uru wāhanga whakarewa. He rite te tukanga, te rerekētanga takoto i roto i te meka e te tikanga kia matua whakaritea te tūemi paiherea i roto i te wahi ki te rawhi atu tikanga ranei, me ki te neke i te mutunga o te kawehiko te kore tika haere te tui, me te nekehanga kōpekapeka o te pokapū tahi ka he tōhihi Weld i roto i te ahunga o te tetahi tuatahi ka te tahi atu āta, wāhanga neke haere te tui, reira tūhono ratou.

mai te angitu i te wheako - te mea matua. Na roto i te hoko i te reira, ka taea e koe hei utu te whakamahi i te ratonga o ngā tohunga o waho (mo te rota rawa o te moni) ki te ako pehea ki te kawe i roto i te mahi fehokotaki'anga ki o ratou ringa. Ngā manaakitanga pai ako me te mahi!
