Published capability snapshot
Triumph publishes 1700W limits of 5.5 mm stainless, 4.5 mm carbon, 4.0 mm aluminum and 4.5 mm galvanized. OMTech publishes 2 mm aluminum and up to 4 mm stainless/carbon steel on its 1500W page. Different test assumptions mean these are not laboratory-equivalent numbers.
Facility and portability
Triumph lists single-phase 220V and an 88 kg net machine for the air-cooled system. Verify the exact OMTech electrical/cooling package before treating it as the simpler installation.
Buying channel
Triumph exposes a USA-warehouse option and direct Add to Cart. OMTech also sells directly online. Compare delivered price, warranty, return rules and local support rather than just the cart subtotal.
