W&S InvertaSpot NexGen Spot Welder (471011NG)

Wielander & Schill InvertaSpot NexGen Spot Welder (471011NG)

The InvertaSpot NexGen is the latest mobile resistance spot welder from Wielander & Schill. It automatically detects the conditions at every joint and sets all welding parameters independently, delivering safe, precise welds on every pull of the trigger. Whether you are working with high-strength steel, ultra-high-strength steel, thin sheet metal, or galvanised panels, the NexGen handles it all.

Part exchange available: trade in your existing spot welder for up to £2,500 — subject to inspection. Call 01327 300700 for a valuation.

Key Features

• Automatic parameter detection – the machine reads the joint conditions and sets current, time, and pressure automatically. No manual guesswork required.
• Lightweight C-Trafo gun – weighs less than 10 kg with a 360° rotating handle and 5 m hose package, reducing operator fatigue during long repair sessions.
• Quick-change C-electrode arm system – swap between C-Arm No. 1 (150 × 70 mm), C-Arm No. 2 (wheel arches), and C-Arm No. 4 (350 × 450 mm) in seconds — all three included in the sale package.
• Colour touch display – intuitive, user-friendly interface with self-explanatory symbols. No training manual needed.
• Pre-installed OEM programmes – factory-loaded welding parameters for Mercedes-Benz, Volkswagen Group, and BMW (OEM-specific arm packages and colour options available).
• Continuous process monitoring – the machine monitors every parameter in real time and displays actual values on screen, ensuring maximum process reliability.
• Height-adjustable balancer – 130° working range, adjustable up to 2.4 m height, keeping the gun supported and easy to manoeuvre.
• Optimised cooling system – liquid cooling with heat exchanger and fan for sustained, high-duty-cycle welding.
• Integrated track widening – swivel and brake castors provide maximum stability when repositioning around the vehicle.
• Job data management – documents and stores weld data for audit trails and quality reporting.
