Abaweesi ba digito okutwalira awamu ba welders za digital. Digital welders zifugibwa DSP, ARM n’ebirala ebiteekeddwamu microprocessors, nga kino kye kitundu ekikulu eky’okukulaakulanya welder. Bw’ogeraageranya n’abaweesi ab’ennono, balina engeri zino wammanga:
1. Emirimu egy’obugagga .
Omulimu gw’ekyuma kya welding eky’ennono gutuukirira n’enkulungo nnyingi eza analog ne logic, buli mulimu ogw’okweyongera gulina okwongerwako ebitundu bingi, okubeera n’omulimu bibiri oba okusingawo kyetaagisa circuit board nnyingi, nga si kyokka nti zisobola okulongoosa ennyo omuwendo gw’okuweta, era omulimu n’obwesigwa bw’ekyuma kya welding bijja kugwa nnyo, n’okweyongera kw’ebitundu by’okuwunyiriza kale it’s difficult to traditional welding machine will be variety of integrated in a variety of a welder.
Omulimu gwa digital welder gutuukirira software. Omulimu gwa digital welder gusobola okugattibwako nga tukyusa software yaayo yokka. Buli modulo y’emirimu tefa ku ndala, okugattako emirimu emipya tekijja kukosa mulimu n’omulimu ogwasooka.
2. Okukwatagana kw’ebintu okulungi, okukola obulungi era okwesigika .
Esalawo eby’obutonde bw’ebitonde by’omuweesi ow’ennono byesigamye ddala ku mpisa z’omulimu gwa paramita za buli kitundu, ebipimo by’ekitundu eby’obutakwatagana biviirako butereevu obutakwatagana, omulimu gw’ekyuma ekiweweeza n’ebitundu by’okufulumya kwonna kw’omukozi biyinza okukakasa nti parameter yaayo ddala, n’olwekyo etera okulabika ng’ekika kye kimu eky’ekyuma ekiweweeza n’ekizibu eky’enjawulo. Okugatta ku ekyo, ebipimo by’ebitundu bijja kukyuka n’enkyukakyuka y’ebbugumu, obunnyogovu n’obutonde obulala, kale omulimu gw’ekyuma ekiweta gujja kuba mulungi era gubi.
Digital circuits teziwulirizibwa ku component parameters, gamba nga input oba output resistance zikyuka okuva ku 1K okudda ku 10K awatali kukosa performance ya welder. N’olwekyo, obutakyukakyuka n’obutebenkevu bwa digital welder bisinga nnyo okusinga omuweesi ow’ennono.
3. Okwesigamizibwa okw’amaanyi .
Ekyuma kya digital welding kyettanira okufuga kwa DSP okw’amaanyi, ekiyinza okuzuula mu budde n’okutereeza okusosola okukulu okwa magineeti, mu ngeri entuufu okwewala okwonooneka kw’ekyuma ekiweta olw’okusosola kwa magineeti okukulu, era ne kulongoosa nnyo okwesigika kwakyo; nga zirina emirimu gya undervoltage, overvoltage n’okukuuma ebbugumu erisukkiridde; IGBT yayawulwa mu mudumu gw’empewo okwewala enkuba, enfuufu n’ebirala ebyonooneddwa ku muweesi. Okugatta ku ekyo, olw’okukozesa tekinologiya wa digito, kikendeeza nnyo ku muwendo gw’ebitundu, kitereeza obwesigwa bwa circuit.
4. Obutuufu bw’okufuga okw’amaanyi .
Obutuufu bw’okufuga kwa analog okutwalira awamu busalibwawo ensobi ereetebwa omuwendo gwa paramita y’ekintu n’ensobi ereetebwa ebipimo by’engeri ezitali nnungi ez’ekifuulannenge eky’okukola. Kizibu okutuuka ku kufuga okutuufu okw’amaanyi. Naye, obutuufu bw’okufuga kwa digito bukwatagana n’ensobi yokka ey’okugerageranya (quantization error) ey’enkyukakyuka ya modulo-ennamba n’obuwanvu bw’ekigambo enkomerero y’enkola, kale okufuga kwa digito kuyinza okufuna obutuufu obw’amaanyi. Naddala ku nkola za welding ez’omulembe nga protection ya pulse, ebyetaago by’okufuga amaanyi ga arc bikakali nnyo. Okutuukiriza ekigendererwa kya NO spatter, short arc ne low thermal input, current ne voltage ya buli pulse zirina okufugibwa precisely okutegeera ddala enkyukakyuka ya pulse n’okugwa kwa base value.
5. Omutindo gwa welding omulungi ennyo .
Abakugu awaka n’ebweru w’eggwanga bakoze omulimu munene ku ngeri y’okulongoosaamu omutindo gw’okuweta, era ne bateeka mu maaso enkola nnyingi ennungi ennyo ez’okufuga okubala, naye bino ebikozesebwa mu kubala ebizibu bizibu okuteekebwa mu nkola mu kiwero kya analog eky’ennono, kubanga kyetaagisa circuit ezizibu ennyo, kale kibadde mu mutendera gw’enzikiriziganya okumala ebbanga eddene. Okujja kwa digital welders kifuula models zino ez’okubala okwangu okussa mu nkola ku welders.
