The Ally5 cups is an AC/DC polarity cup and has an amperage rating of 200 amps,
It is Furicks “go to” cup when welding thinner aluminum assemblies and need great visibility. It is made of Quartz laboratory grade glass and can withstand the high heat environments associated with welding on AC. Be careful not to slam cup and we do not recommend “walking the cup” with any Furickcups made of glass.
All glass cups are subject to pick up dirt and debris as are ceramic style cups. Use these accordingly and try to refrain from welding on dirty /oily applications that would spit back at glass and impede visibility.
