FAQ

  • AC spot welding is a proven, cost-effective choice for standard sheet metal welding. DC Mid-Frequency spot welding provides more controlled current delivery and is often selected for demanding production, automation, or robotic applications.

  • Machine size depends on material type, sheet thickness, weld size, weld count, part geometry, throat depth, stroke, production rate, and required weld quality.

  • Power is the welder’s ability to deliver electrical energy to the weld. More current produces more heat at the weld interface, so higher power supports thicker or more conductive materials when paired with the right force and timing.

    Capacity describes the practical welding range of the machine, including the material type, thickness, current, and electrode force it can handle reliably.

    Throat depth is the horizontal distance from the electrodes back to the nearest machine obstruction, which determines how far into a part the machine can place a weld. A deeper throat allows for larger parts to be welded.

    Vertical stroke is the up and down travel of the welding head or ram as it opens, closes, and applies electrode force to the workpiece. More stroke gives more clearance for loading formed or taller parts, while adjustable or retractable stroke options help match the machine motion to the application.
