(1) Inert gas yog tsis tu ncua tshuab los ntawm vuam nozzle kom tag nrho cov vuam cheeb tsam, tiv thaiv cov weld hlaws los ntawm oxidized los ntawm oxygen nyob rau hauv cov huab cua. Vim hais tias ib tug loj tam sim no yog concentrated nyob rau hauv lub vuam cheeb tsam, lub tshav kub yuav tsum concentrated nyob rau hauv lub zos sai heev rau welding, uas ua rau tsawg deformation.
(2) Lub vuam hlau yog txiav thiab tsis tu ncua pub, yog li tsis muaj qhov sib txuas, tso cai rau kev ua haujlwm txuas txuas ntxiv.
(3) Qhov kub nce yog tsawg, tso cai rau lub pob tw vuam ntawm nyias daim hlau. Thaum ua cov welding npog, tsis muaj slag yog tsim los ntawm cov hlaws weld, tshem tawm qhov xav tau rau kev tshem tawm slag.
(4) Lub tshuab vuam rau kev kho lub cev, suav nrog cov xaim pub mis thiab lub tshuab vuam lub cev, yog ntsia rau ntawm lub laub log nrog rau lub tog raj kheej roj, ua kom yooj yim txav mus los ntawm qhov chaw ua haujlwm.
(5) Lub tshuab vuam rau kev kho lub cev yog nruab nrog MIG qhov chaw vuam tshuab, tso cai rau ib qho -ib sab qhov chaw vuam. Qhov no yog tshwj xeeb tshaj yog zoo rau cov cheeb tsam uas electrode clamping caj npab tsis tuaj yeem ncav cuag qhov chaw vuam.
