Exceptional Arc Stability for Precision Welding 

Superb instant TIG soft arc strike and outstanding stable arc at very low amps due to the unique 80khz high speed control developed by OTC DAIHEN. This machine has been impressing aerospace customers welding thin wall precise stainless steel and titanium to cut weld rejects on difficult applications (GKN Aerospace purchased 27 of these machines for their factory on the Airbus site at Filton, Bristol). The DT-303 DC power source can also be utilised with the WeldUniverse Data Logging Management System, also recently developed by OTC DAIHEN, to further improve efficiency and weld quality on many critical applications.
