Battery-operated DC spot welding system with current monitoring. The Hybrid Spot now features weld current monitoring to show the operator how much current is delivered to each weld. The unit can also alert the user when the weld current falls below a preset level. The Hybrid Spot Resistance Spot Welder provides a great alternative spot welder where 3 phase power is not available or overloaded. The battery-operated welder delivers high amperage DC weld current designed to produce powerful spot welds. No input power is required to operate the welder. The built-in charging system is capable of charging all batteries at the same time.
