Unlike capacitive discharge (CD) welders — which store energy in capacitors and release it in a fast, discrete pulse — AC welders flow energy continuously for as long as the trigger is held. This makes AC welding the correct technology for seam welds, foil sealing, and mesh welding, where a continuous, uninterrupted bond is required. CD welders are better suited for discrete spot welds, thermocouple junctions, and fine battery tab welding.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCan the Wave AC make standard spot welds, or is it only for seam welding?\u003c\/strong\u003e Both. The Wave AC supports single-cycle and repeat-cycle spot weld modes in addition to seam mode. However, if discrete spot welds are your primary application — battery tab welding, cross wire welding, thermocouple junctions — a CD welder like the CDDP-A is likely a better fit. The Wave AC's core strengths are continuous seam welding, foil sealing, and mesh welding.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eDoes the Wave AC require special electrical installation?\u003c\/strong\u003e Yes. The Wave AC requires a \u003cstrong\u003e200–250VAC single-phase power supply\u003c\/strong\u003e, which is not the standard 120V household or light commercial circuit. Most manufacturing facilities already have 208V or 240V single-phase circuits available. If yours does not, a licensed electrician will need to install a dedicated circuit before the machine can be used.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhat attachments are typically used with the Wave AC?\u003c\/strong\u003e The Wave AC is most commonly paired with a roller hand piece (such as the Sunstone PG2) and a wheel electrode for continuous seam welding. The roller electrode rolls along the surface as the operator guides it, with the Wave AC delivering continuous weld energy through the wheel. For spot weld modes, standard opposed or parallel electrode attachments can also be used.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCan the Wave AC weld pouch cell batteries?\u003c\/strong\u003e Yes — pouch cell sealing is one of the Wave AC's primary applications. The machine's seam mode delivers a continuous hermetic seal around the foil perimeter of the pouch, creating a gas-tight closure that a spot welder cannot replicate.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eHow many weld schedules can the Wave AC store?\u003c\/strong\u003e The Wave AC stores up to \u003cstrong\u003e100 weld schedules\u003c\/strong\u003e. Each schedule saves a complete set of parameters — power level, phase percentage, cycle count, weld mode — for instant recall. This makes job changeovers fast and eliminates re-setup time for recurring applications.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhat maintenance does the Wave AC require?\u003c\/strong\u003e Primary maintenance involves regular \u003cstrong\u003eelectrode cleaning and inspection\u003c\/strong\u003e — worn or contaminated electrodes are the most common source of weld quality degradation. Additional maintenance includes monthly cleaning of cooling vents to prevent overheating, quarterly overall inspection, and annual visual and resistive checks of welding cables. The machine's digital control system requires no calibration maintenance under normal operating conditions.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhat is your return policy?\u003c\/strong\u003e 75-day returns.
