1. Kev tsim khoom raws li qhov xav tau, tsis tas yuav tsum tau khaws cia, muaj kev nyab xeeb thiab yooj yim dua li lub raj mis roj.
2. Cov ntaub ntawv nyoos yooj yim, tsuas yog xav tau dej thiab hluav taws xob xwb; kev tsim khoom yog tam sim ntawd thaum pib, kev lag luam thiab siv tau; portable heev, compact, thiab haum rau kev khiav hauj lwm teb.
3. Concentrated nplaim taws, haum rau precision nplaim ua.
4. Oxyhydrogen thiab hydrogen tsis muaj ntxhiab tsw thiab tsis yog- tshuaj lom; combustion khoom tsuas yog dej, ua rau tsis muaj kuab paug ib puag ncig.
5. Oxyhydrogen nplaim yog cov pa roj carbon - dawb nplaim, ua rau muaj zog welds tsis muaj carbon embrittlement.
