HD-300 Large through-hole 100kg pipe flange positioner argon arc welding foot welding turntable automatic flipping table

The HD-300 is a large through-hole welding positioner / turntable designed for argon arc (TIG/GTAW) and foot welding of pipe flanges and other round or cylindrical workpieces. It's intended for machine shops, construction, manufacturing plants, and repair shops.

Workbench diameter: 500 mm. Workbench through-hole diameter: 90 mm. Workbench height: 650 mm. Tilt (rotation) angle: 0–90°. Workbench rotation speed: 0.2–2.5 rpm (variable).

The listing contains mixed values: the product name/marketing references a 100 kg capacity, while the technical line shows 'Maximum load Q: 300' and 'Maximum load torque M: 150'. Please confirm the required rated capacity with the supplier before purchase to ensure it meets your part weight and torque requirements.

Input power: AC 220 V, single-phase, 50 Hz. Drive motor: DC 220 V, 200 W. Welding rated current is listed as 800 (please confirm whether this refers to the maximum current of the welding power source supported).

The HD-300 is compatible with KD series chucks—KD300, KD400, and KD500—allowing use of common pipe and flange fixtures sized to those chucks.

Yes. The product is specified for argon arc welding and mentions foot welding/foot control operation, which is common for TIG welding. Confirm interface requirements for your welding power source and foot pedal.

Listed dimensions are 650 × 800 × 675 mm. Net weight is approximately 102 kg; another line lists 110 kg — expect a shipping weight around 102–110 kg depending on accessories and packaging.

Warranty for core components (engine/motor) is stated as 1 year. For detailed warranty coverage, spare parts availability, and service response, contact the seller or manufacturer.

The unit provides variable rotation speed (0.2–2.5 rpm) and a 0–90° tilt. It is marketed as easy to operate; typical controls include speed adjustment, start/stop and tilt lock. Exact control layout may vary—request a user manual or control-panel photo from the supplier.

Standard recommendations: emergency stop, mechanical locks for tilt and rotation, proper grounding, load limits and holding devices for workpieces, and safety guards where needed. Verify which protections are factory fitted and add guards or interlocks per your shop safety rules.

Yes—it's designed for pipe flanges and cylindrical parts and works with KD chucks for secure clamping. Ensure the part weight, diameter and clamping method are within the machine's rated capacity and chuck compatibility.

Provide a stable, level mounting surface capable of supporting the unit plus the maximum workpiece weight. Single-phase 220 V power supply is required. Allow space for operator access, welding cables, ventilation and fume extraction. Anchor or bolt the unit if recommended by the manufacturer.

The provided description lists 'Video outgoing-inspection' and 'Machinery Test Report' as Not Available. Ask the supplier for available test documentation, CE/UL certifications if required, and factory acceptance test reports before purchase.

Perform regular maintenance: keep the worktable and spindle clean, lubricate bearings and gearboxes per the manual, inspect electrical connections, check and tighten clamps and fasteners, and replace worn parts. Establish a schedule based on usage and request the manufacturer's maintenance manual.
