• inverters yog insensitive rau tsawg mains voltage;
• inverters tsis muaj teeb meem nrog ignition ntawm vuam arc;
• Txawm tias ib tug novice welder tuaj yeem siv lub inverter.

Tau kawg, kuj muaj qhov tsis zoo:

• nyob rau hauv cov txheej txheem vuam, tuab electrodes nrog ib txoj kab uas hla ntawm 3-5 hli yog siv, thiab tsis yog hlau;
• Thaum lub sij hawm inverter vuam, cov npoo ntawm cov hlau raug welded yog kub heev, uas tuaj yeem ua rau thermal deformation;
• lub seam ib txwm hloov tawm thicker dua thaum vuam nrog ib tug semi-automatic ntaus ntawv.

Yog li koj yuav tsum xaiv txoj kev twg?

Qhov kev pom zoo dav dav yog qhov yooj yim: yog tias koj npaj yuav vuam ib ntu ntawm lub cev uas pom tau yooj yim, thiab tus tswv lub tsheb tsis txwv los ntawm cov nyiaj thiab muaj qee qhov kev paub nrog lub tshuab vuam, ces cov khoom siv semiautomatic yog qhov kev xaiv zoo tshaj. Thiab yog tias qhov kev puas tsuaj tsis pom los ntawm sab (piv txwv li, hauv qab tau raug puas ntsoog) thiab tus tswv ntawm lub tshuab ua haujlwm tsis zoo hauv vuam, ces nws yog qhov zoo dua los ua noj nrog inverter. Txawm hais tias tus pib ua yuam kev, nws tus nqi yuav tsis siab.

Kev npaj thiab txheeb xyuas cov khoom siv

Txawm hais tias txoj kev vuam twg tau raug xaiv, ntau qhov kev npaj ua haujlwm yuav tsum tau ua.

Npaj rau semi-automatic vuam ntawm lub cev tsheb

• ua ntej pib ua hauj lwm, tus welder yuav tsum xyuas kom meej tias cov lus qhia channel nyob rau hauv lub welding torch sib tw rau txoj kab uas hla ntawm cov hlau siv;
• txoj kab uas hla ntawm cov hlau yuav tsum raug coj mus rau hauv tus account thaum xaiv ib qho kev sib txuas;
• lub nozzle ntawm lub apparatus yog soj ntsuam rau hlau splashes. Yog hais tias lawv yog, lawv yuav tsum tau muab tshem tawm nrog sandpaper, txwv tsis pub lub nozzle yuav sai sai poob.

Dab tsi yuav tsum tau ua ua ntej pib lub inverter

• kev ntseeg tau ntawm electrode fastenings yog ua tib zoo xyuas;
