Li-welders tsa DC tsa Mid-frequency ke lisebelisoa tsa bohlokoa liindastering tse fapaneng, tse fanang ka ts'ebetso le bokhoni ba ho kopanya likarolo tsa tšepe. Leha ho le joalo, joalo ka mechini efe kapa efe e rarahaneng, ba ka kopana le mathata a hlokang ho rarolloa le ho lokisoa. Sehloohong sena, re tla tšohla mathata a tloaelehileng a kopaneng le li-welders tsa DC tse bohareng ba maqhubu le mokhoa oa ho li rarolla ka katleho.
1. Ha hona Welding Current Output
Ha spot welder ea hau e hloleha ho hlahisa welding current, qala ka ho lekola phepelo ea motlakase. Netefatsa hore mochini o hoketsoe hantle mohloling o tšepahalang oa matla le hore sekhechana sa potoloho ha se khoptjoa. Haeba phepelo ea motlakase e ntse e le teng, hlahloba likhoele tsa ho tjheseletsa bakeng sa tshenyo efe kapa efe kapa dikgokelo tse hlephileng. Lithapo tse fosahetseng li ka sitisa phallo ea hona joale, e leng se etsang hore ho se be le tlhahiso. Tlosa kapa u lokise likhoele tse senyehileng ha ho hlokahala.
2. Uneven Welds
Li-welds tse sa lekaneng e ka ba taba e nyahamisang, hangata e bakoang ke khatello e sa lekaneng kapa ho se tsamaisane hantle ha li-workpieces. Ntlha ea pele, netefatsa hore li-electrode tsa welding li hloekile ebile li boemong bo botle. Ka mor'a moo, etsa bonnete ba hore li-workpiece li hlophisitsoe hantle 'me li tiisitsoe ka thata. Fetola khatello ea welding le matla a electrode ho fihlela weld e tsitsitseng. Haeba bothata bo ntse bo tsoela pele, ho ka 'na ha hlokahala hore u hlahlobe' me, ha ho hlokahala, u nke sebaka sa malebela a welding kapa li-electrode.
3. Ho futhumala ho feteletseng
Ho futhumala ho feteletseng ke bothata bo tloaelehileng ho li-welders tsa letheba 'me ho ka lebisa ho fokotseng ts'ebetso esita le ho senya mochine. Ho rarolla bothata bona, pele, etsa bonnete ba hore mochini oa ho cheseletsa o pholile ka ho lekaneng. Hloekisa mokhoa oa ho pholisa, ho kenyeletsoa li-fan le li-filters, ho netefatsa hore moea o phalla hantle. Ho feta moo, hlahloba hore na ho na le litšitiso life kapa life tse potileng mochini tse ka sitisang ho pholisa.
4. Ho se sebetse ha Panel ea Taolo
Haeba phanele ea taolo e bonts'a liphoso kapa ho se sebetse hantle, sheba buka ea mosebelisi bakeng sa litlhaloso tsa khoutu ea liphoso le tataiso ea ho rarolla mathata. Li-welders tse ngata tsa sejoale-joale tsa DC li na le likarolo tsa tlhahlobo tse ka thusang ho supa bothata. Haeba bothata bo ntse bo tsoela pele, ikopanye le tšehetso ea bareki ba moetsi bakeng sa thuso e eketsehileng.
5. Ho Sparking ho Feteletseng
Ho phatloha ho feteletseng nakong ea ts'ebetso ea welding ho ka ba kotsi mme ho ka supa bothata ka li-electrode kapa li-workpieces. Sheba boemo ba li-electrode tsa welding 'me u netefatse hore li tsamaisana hantle le ho kopana le li-workpieces. Lekola bokaholimo ba lisebelisoa bakeng sa litšila tse kang mafome, pente kapa oli, kaha li ka baka tlhase. Hloekisa bokaholimo hantle pele u leka ho cheselletsa.
Qetellong, li-welders tsa DC tse bohareng ba maqhubu ke lisebelisoa tsa bohlokoa ho hlahiseng le ho etsa masela, empa li hloka tlhokomelo ea kamehla le ho rarolla mathata ho netefatsa ts'ebetso e nepahetseng. Ka ho rarolla mathata a tloaelehileng joalo ka ho se be le tlhahiso ea hona joale ea tjheseletsa, li-welds tse sa lekanang, ho futhumala ho feteletseng, ho se sebetse hantle ha phanele ea taolo, le ho hlanyetsa ho feteletseng, o ka boloka sebaka sa hau sa welder se sebetsa hantle 'me sa lelefatsa bophelo ba sona. Haeba u thulana le mathata a mangata, u se ke ua tsilatsila ho batla thuso ea litsebi ho qoba tšenyo e eketsehileng le ho fokotsa nako.
