Used Peddiwriter 1250 Automated Layout Marker

Machine Information


  • Mark on all 4 sides of a profile as a standalone operation.
  • Layout faster and more effectively than ever before with a dual torch system.
  • Minimize the potential for human error by eliminating manual measurement
  • Minimize the overhead and human error associated with manually laying out and marking weld data onto a profile
  • Streamline material handling by minimizing crane lifting of a section to and from a layout station
  • Easily integrate into your existing Peddinghaus system due to a modular design

General Machine Design

The all new PeddiWriter from Peddinghaus Corporation is a fully automatic marking tool that consists of two independantly operating plasma marking torches – each independant of the material’s X-Axis motion. With the aid of Peddinghaus’ modern rollerfeed measurement system the PeddiWriter can be easily integrated into an existing shop layout.

Two Independant Torch Assemblies:

THE TOP TORCH assembly of the PeddiWriter consists of 1 multi-axis articulating head with Hypertherm ArcWriting torch and independent rack and pinion motion system. This independent system allows for motion in the X, Y, and Z axes separately from all other operations.

This allows the top torch to mark data separate from the marking on the underside of a profile, while still maintaining simultaneous operation.

Maintaining a 24″ (600 mm) marking envelope without the need to index material, the PeddiWriter utilizes Siemens Servo motors with feedback to measure the travel of the marking unit while maintaining fully automatic operation.

The articulating head of the top torch enables it to facilitate marking on both the top and bottom flanges as well as the top surface of the profile.

THE BOTTOM TORCH assembly of the PeddiWriter also maintains a Hyptertherm ArcWriting unit and operates completely independent X, Y, and Z motions from that of the top torch and material drive system.

This entire marking unit lifts to mark material on the underside of a profile.

Continuous Torch Probe Mechanism:

Plasma marking (similar to plasma cutting) requires optimal standoff distance to maintain arc, and process a profile in an ideal manner. In traditional systems that rely on plasma cutting or marking this is commonly achieved by repeditive torch probing via electronic feedback, or mechanical mechanism.

The PeddiWriter utilizes a technologically advanced mechanical system with roller contact bearings that allow the system to maintain optimal standoff distance, while minimizing the need to probe the material repeatedly. Surface detection is achieved via two standard proximity switches. A first switch is triggered and identifies the surface of material whilst the second switch detects overtravel, protecting the mechanism from damage.

Hypertherm AcrWriting

The PeddiWriter utilizes 2 independant Hypertherm ArcWriting torches, each with units mounted directly on the main machine assembly. Output of the ArcWriter varies between 4-19 amps, and is adjustable in 1 amp increments. These plasma marking units operate using either H5 Gas (5% Hydrogen and 95% Argon) or Shop Air.


  • Light Marking Depth: Less than 0.001 inch / 0.03 mm
  • Heavy Marking and Scoring Depth: 0.003-0.010” / 0.08-0.25 mm
  • Punch Mark or Dimple Depth (only available for “pop marking”): 0.020-0.040“ / 0.5-1.0 mm

Roller Measurement System:

A reliable, accurate, and repeatable measurement system is the backbone of any modern machine tool. Peddinghaus roller measurement, with adjusting height capability allows for superior accuracy, while maintaining total production throughput.

Single Roller Disks on the entry and exit of the machine with integrated encoders will adjust up/down to measure from the most true position of a profile (at the flange of a beam, heel of an angle, etc.).

Each disk is paired with a deslagging roller to eliminate the opportunity for slag or dross to interfere with the measurement process.
