Herbert arnold Zenith 40 or GGT Mirage ? Hello there , I'm from Argentina alfredo . I am in doubt that torch buy. I have 5 HA Zenit 40. I have to buy new torches , because those who I have already have over 20 years of use and are somewhat covered. Someone could compare ? I work exclusicamente glass schott borosilicate 3.3 . 9 mm to 100 mm in workbench. thank you very much.

GTT triple mixes are high pressure low volume and the Zenit is high volume low pressure. GTTs tend to be more oxygen efficient yet can be more forceful and harder on crayon colors. Zenits are great torches for working hollow and GTTs are great for large solid work. I own one of each since they can complement each other. All my opinion of course.
