Why is the Bosch 90 Amp more reliable than other welders that utilize “high-output” 160-200+ amp alternators?
The Bosch 90 amp is engineered not only to produce 90 amps but also to cool efficiently and properly while producing 90 amps. If the amount of windings within the alternator are increased in order to generate 160+ amps, then the size of the alternator must also increase to allow for proper cooling. Without a substantial increase in the physical size of the alternator, such a “beefed up” alternator is subject to chronic cooling difficulties, especially when a welding machine taps it for maximum amperage. Consequently, these “high-output” alternators can be unreliable because they may overheat and fail! The Mobi Weld pulls 90 amps from an alternator that was engineered to produce 90 amps, then kicks the power box using solid-state technology to produce welding power, like 110 current and, most importantly, reliable battery charging during day to day driving. A reliable alternator is key!
