Compared to older, bulky, standard workshop welders, Compact Inverter Welders are much smaller and lighter yet have a 70- up to 160-amp welding capacity, due to significant internal differences. They also operate off 120- as well as 220-volt power supplies, which may be important for outside-the-shop welding needs. These features can make Compact Inverter Welders a good choice for making repairs around the farm.
