1. Thaum tshav kub kub tsis kam
Lub luag haujlwm tseem ceeb yog los tiv thaiv ob txhais tes los ntawm cov cua kub uas tshwm sim thaum vuam. Vuam hnab looj tes yuav tsum tiv taus kub tshaj 500 degree F (260 degree) thaum lub sij hawm txheej txheem xws li vuam nrog stick welding.
Rau cov ntawv thov kub kub, hnab looj tes ua los ntawm Kevlar lossis Aramid fibers, tib cov ntaub ntawv siv hauv cov khaub ncaws flameproof, muab kev tiv thaiv zoo heev.
2. Durability thiab kev tiv thaiv
Tawv muab kev nyab xeeb muaj zog tiv thaiv cov nplaim taws thiab cov hlau molten, txo qhov kev pheej hmoo ntawm kev kub nyhiab lossis kev txiav. High-hnav cov cheeb tsam yog zoo ntxiv dag zog rau ntawm xibtes rau ntxiv durability.
3. Dexterity thiab xis nyob
Kev tiv thaiv yog qhov tseem ceeb tshaj plaws, tab sis koj kuj yuav tsum muaj kev tswj xyuas thiab qhov tseeb thaum vuam. Cov hnab looj tes uas hnyav dhau los yog nruj dhau tuaj yeem cuam tshuam koj lub peev xwm ua haujlwm cov cuab yeej thiab ua cov ntsiab lus zoo.
Cov hnab looj tes vuam zoo feem ntau yog ua ntej nkhaus. Cov qauv tsim pab cov hnab looj tes kom haum lub ntuj zoo ntawm tes, tso cai rau kev ua haujlwm ntau dua thiab tsis muaj zog.
Tso cai rau tes kom txav mus los. Cov hnab looj tes uas nruj dhau tuaj yeem ua rau tsis xis nyob, thaum cov hnab looj tes xoob dhau tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov khoom siv.
