Backup Electric Power Design Considerations- Part 3, by Duliskov
Batteries can generate, without damage, several hundred amperes of DC current for short periods of time. In fact, you can arc weld using a battery. There are welders designed to run from battery power alone or able to run either from internal batteries and/or supplementing utility power with internal battery power. Though the Hobart Trek 180 welder, which I recommend, may have been discontinued or currently unavailable, it is useful if you wish to achieve higher amps than is possible via a single 120V household outlet. The higher the battery’s amperage, the easier the battery can start a car engine, …
