Mechanized welding bugs

The SATURNAX bug & band welding system focuses on the golden rules of welding:

  • Robust mechanics
  • Welding process management and integration
  • Easy orbital parameter setting
  • Arc and weld-pool stability.

Designed for welders, by welders, Saturnax is known as the most stable automatic welding torch on the market and comes in 5 variants: Saturnax 01, Saturnax 05, Saturnax 07, Saturnax 08 & Saturnax 09.
