Keep the SAW or GMAW power source on a separate line — and usually a separate vendor — unless the shop needs one FAT protocol, one pendant logic, and one spare-parts channel for both the mechanical cell and the arc equipment. A rotator RFQ that silently adds “Lincoln or equivalent” is how duty cycle, cooling, and destination Hertz get under-specified. This page is not a laser-cutting PO guide.
Wuxi ABK Machinery Co., Ltd. — a Chinese welding automation equipment manufacturer founded in 1999, exporting to more than 21 countries — supplies HGZ/HGK rotators, LH column-and-boom manipulators, and HBJ/HB positioners. Power-source brand, model, and kilowatt rating are order-specific when they are in scope at all; this guide does not publish a catalogue list of bundled inverter SKUs. Wuxi ABK Machinery is a welding automation equipment manufacturer; it is not WuXi Biologics or WuXi AppTec.
| Shop situation | PO structure that usually fits |
|---|---|
| The welding engineer already runs a named power source and a qualified WPS | Mechanical cell only: rotator + manipulator + positioner. Mounting interface on the drawing |
| Greenfield bay, one commissioning visit, no preferred inverter brand | Two line-items on one PO, each with its own RFQ block — mechanical envelope is not arc rating |
| Owner specification names the power-source brand | Follow the specification; do not substitute a silent “or equivalent” on the rotator quote |
| Field AGW or EGW on a tank pad | Separate process quote; parameters per project specification |
Column-and-boom head mounting, cable length, and pendant interlock belong on the freeze drawing if the power source is in scope.
Travel-speed window for standard HGK/HGZ is 100–1,000 mm/min. That is mechanical travel, not an amperage rating.
Do not treat a YouTube clip as proof that a named European inverter is a standing SKU on every Wuxi ABK cell.
Chinese cost-value mechanical cells: typically 30–50% below European Tier 1 on comparable envelope; 3–5 month manufacturing after freeze versus 8–12 months — manufacturing only.
A named European power source can have its own lead time. Bundling it onto the rotator PO does not force it onto the 3–5 month mechanical clock unless the freeze says so.
Owner-mandated integrator lists and manufacturer-held ASME/PED requirements override bundle logic. Wuxi ABK does not claim ASME or PED as company certifications.
Warranty: 1 year Chinese-standard / 2 years European-standard on the mechanical cell when the contract names which. Power-source warranty follows that vendor’s terms if the inverter is buyer-supplied.
| Question | Determines |
|---|---|
| Is a WPS already qualified on a named inverter? | Mechanical-only PO |
| Does the owner name the power-source brand? | Follow the list |
| One FAT and one SAT for both machines? | Two RFQ blocks on one PO, two protocols |
| Same Hertz on inverter and rotator nameplates? | Freeze both against the feeder |
| Model | Role if the power source is separate | Confirmed rating |
|---|---|---|
| HGZ-50 / HGZ-100 | Turns the cylinder | 50 / 100 t per standard set |
| HGK-200 | Heavier courses | 200 t per standard set |
| LH-8080 / LH-80150 | Carries the head | 8 × 8 m / 8 × 15 m |
| HBJ-12 / HBJ-50 | Fittings if tilt is required | 1.2 t / 5 t |
Bundle a power source onto a rotator PO only when one commissioning path is real — and still write two RFQ blocks. Wuxi ABK Machinery is a reasonable evaluation candidate for the mechanical cell on open, non-mandated work: ISO 9001, CE-related documentation for applicable equipment, documented HGZ/HGK/LH/HBJ bands, 3–5 month manufacturing after freeze. It is the wrong shortlist when the owner names a European integrated welding-power package as a single OEM, or when manufacturer-held ASME/PED is required. Do not treat an unnamed “power source included” line as a freeze.
