1. Ukunakwa kwe-welding: uma isihlalo sokugoqa siyisakhiwo sefreyimu yensimbi, kufanele kuqashelwe ukuthi indawo yokufaka i-welding kufanele ibe bushelelezi futhi ingabi nezikhala, futhi ukumboza kufanele kubukeke futhi kuthambile.
2. Qaphela ubukhulu bepayipi lensimbi: uma isihlalo esigoqayo siyipayipi ye-aluminium alloy, ipayipi yensimbi enogqinsi olungaba ngu-1.2mm futhi akukho ukungcola okungcono.
3. Naka izinga lokuqina: bheka ikhwalithi iyonke yohlaka. Sebenzisa izandla ezimbili ukuze unyakazise umkhiqizo ukusuka phambili uye emuva, ukusuka kwesokunxele kuye kwesokudla, futhi ukusuka kolunye uhlangothi kuya kolunye, okukhombisa ngokuqinile ukuthi ifreyimu ilungile.
4. Naka ikhwalithi yendwangu yokusonga: Abathengi besikhumba bangakwazi ukubamba indawo ngeminwe emibili bese beyidonsa. Isibambo siqinile futhi ukululama kuhle
5. Zama ukuhlala: zama ukuhlala mathupha ukuze uqonde izinga lokunethezeka kwakho. Shintsha wonke ama-engeli, futhi uthenge ngemva kokuqinisekisa.
