Yuav tsum npaj dab tsi ua ntej vuam cov raj txuas hluav taws xob?

1. Kev npaj cov khoom raj

1. Kev npaj cov khoom raj: Ntxuav tag nrho txheej oxide ntawm saum npoo raj (tshem tawm txog 0.5mm), xyuas kom tsis muaj zaj duab xis oxide seem.
2. Ntxuav qhov txuas: Siv daim ntaub huv los ntxuav sab nraud ntawm raj thiab sab hauv ntawm qhov txuas, tshem xuab zeb, roj, noo, thiab lwm yam impurities kom tsis txhob muaj kev contamination rau qhov txuas molten.
3. Tshawb xyuas cov khoom: Ua kom paub tseeb tias qhov txuas tsis puas, cov hlau tiv thaiv tsis tawg, thiab qhov txuas phim nrog qauv, kev qhia, thiab qhov siab ntawm raj.
4. Calibrate cov cuab yeej: Lub electrofusion welder yuav tsum tau calibrate ua ntej kom muaj voltage ruaj khov (feem ntau 39.5V) thiab tam sim no. Tsis txhob siv hlua txuas ntev dhau vim tej zaum yuav ua rau hluav taws xob poob.tshuab vuamKoj yuav tsum calibrate ua ntej kom voltage tawm (feem ntau yog 39.5V) thiab current nyob ruaj khov, thiab tsis txhob siv extension cord ntev dhau vim nws yuav ua rau voltage poob.
