Nazi zinthu zina zomwe antchito ayenera kukumbukira akawotchera pa weld positioner:
donthoPoganizira zapakati pa mphamvu yokoka (CoG): Pakatikati pa mphamvu yokoka ndi pomwe kulemera kwa chinthu kumasungidwa. Chifukwa chake, mukasankha chowotcherera choyika, ndikofunikira kuganizira zapakati pa mphamvu yokoka ya workpiece pamodzi ndi kukula kwake ndi kulemera kwake. Izi zimathandizira kukhazikika kofanana kwa workpiece pa nkhwangwa zonse. Izi zimatsimikiziranso liwiro la kuzungulira kwa tebulo. CoG idzasintha pamene wowotcherera akuwonjezera magawo a zolemera zosiyanasiyana ndi kukula kwake pa malo. Mfundo imeneyi iyeneranso kuganiziridwa.
donthoKumangirira koyenera kwa chogwiriracho: Momwe chogwiriracho chimamangidwira pachowotcherera ndichofunikira kwambiri chifukwa iyi ndi njira yomwe ingasiyanitse ntchitoyo ikatha. Ntchito zina zomwe zimafunika kubwerezedwanso kuti zitheke kupanga zida zomwe zimagwiritsidwa ntchito nthawi zonse zimagwiritsa ntchito zida zapadera. Kupatulapo izi, zogwirira ntchito zozungulira, nthawi zambiri, chuck ya nsagwada zitatu ingagwiritsidwe ntchito kulumikiza choyikapo. Zidutswa zina zimafunika kumangidwa. Choncho, izi ziyenera kuganiziridwa molingana ndi mawonekedwe ndi kukula kwa workpiece.
donthoYathyathyathya ngakhale pamwamba: Onetsetsani kuti chowotcherera chonsecho chayikidwa pamalo athyathyathya, ngakhale pamwamba. Kupanda kutero, chogwiriracho chikhoza kugwa, ndipo izi zitha kukhala zowopsa. Mutha kuyika choyikapo molunjika pa benchi kapena choyimira; komabe, iyenera kumangirizidwa bwino.
