DEMO | V303: Automatic Arc Lead-In

The V303 ensures consistent cut quality with its automatic arc lead‑in restart feature, engineered to recover cleanly after an interruption without damaging the part. Instead of attempting to reignite directly on the finished edge, the system automatically creates a smart lead‑in in scrap or a safe area, then blends back into the contour with precise timing. The result is a seamless restart that preserves edge quality, prevents gouging, and maintains dimensional accuracy.

This capability is essential for real production environments where stops can occur due to consumable changes, material irregularities, or process interruptions. By restarting the cut correctly every time, the V303 reduces rework, protects material, and keeps jobs on schedule.

Smart restarts that preserve edge integrity

Traditional restarts often leave a visible mark or notch where the arc reenters the contour. The V303 avoids this by calculating a proper lead‑in path and using an arc‑based entry that dissipates heat and stabilizes the plasma or oxy‑fuel process before touching the finished edge. The lead‑in length, angle, and timing are optimized automatically, ensuring that the transition is smooth and the final edge remains consistent with the rest of the contour.

This approach maintains part geometry, prevents local hardening or burn‑in at the restart point, and keeps hole quality and outer profiles within tight tolerances.

Automation that simplifies day‑to‑day operation

The automatic lead‑in restart is fully integrated into the V303 control software. Operators do not need to manually edit paths or guess where to resume. When an interruption occurs, the machine evaluates the current position, selects a safe pierce location in scrap or off‑part, and generates an arc lead‑in that rejoins the contour at the correct point with the correct kerf compensation.

This automation eliminates the trial‑and‑error that can slow down recovery and ensures consistent results regardless of operator experience. The dashboard clearly indicates restart progress, while the scheduling view keeps overall production visibility intact.

Reliable for both plasma and oxy‑fuel

Whether cutting with plasma or oxy‑fuel, the restart behavior is tailored to the process. For plasma, the V303 coordinates with TrueVolt height control to stabilize stand‑off distance during the lead‑in and merge, preserving arc stability and edge quality. For oxy‑fuel, the system accounts for preheat requirements and uses a controlled entry that avoids excessive heat input at the reentry point.

In both cases, the automatic lead‑in prevents crater marks, avoids undercut, and protects small features where a direct restart would otherwise risk part damage.

Consistent results across complex nests and long shifts

During large nests with many parts, interruptions can be costly if restarts are not handled correctly. The V303’s automatic arc lead‑in keeps quality consistent, even when resuming inside tight geometries, near small holes, or along long outside contours. The feature works hand in hand with Instant Cut and Chain Cutting strategies, ensuring that any recovery does not compromise the speed gains achieved by reduced pierces and faster transitions.

Because the restart is clean and predictable, operators can maintain high productivity without slowing down to compensate for potential quality loss.

Protecting material, reducing rework, and maintaining accuracy

By preventing visible restart defects, the automatic arc lead‑in reduces secondary operations such as grinding or edge repair. Parts come off the table ready for downstream processes like bending, welding, or coating. Dimensional accuracy is maintained, so hole fits, bevel transitions, and assembly interfaces remain within spec.

Over time, fewer scrap parts and less rework translate directly into a lower cost per part and a more reliable production schedule.

Designed for industrial reliability and ease of use

The V303’s rigid mechanical platform supports precise restart positioning, while the magnetic torch mount helps operators recover quickly from collisions without losing calibration. When the machine resumes, the lead‑in is generated and executed with the same motion control accuracy used throughout the job, supported by helical rack and pinion drives and preloaded linear guides.

In combination with buffer management and Plate Verification, the V303 ensures that even after an interruption, the transition back to full‑speed production is smooth and dependable.
