The Weld Data Logger represents leading edge technology in arc welding data collection and logging. The micro-controller based weld data acquisition system provides a means of measuring and documenting all basic welding parameters when used with external serial printer or PC.

The WDL-3 can store uo to 4000 weld summeries in non-volatile memory. Additionally the WDL-3 has the unique ability to calculate heat input using the optional travel speed transducer, a user specified Travel Speed or the actual weld length and accumulated arc time. An Ethernet port is available for remote data collection and  stored weld summary data upload.

There are two different Systems Configurations for the WDL-3.

Ethernet System - P/N: A0A0171-ETH
(Enclosure contains built-in auto-sensing 10/100 Mbps Ethernet port)

USB System  - P/N: A0A0171-USB
(Enclosure contains built-in USB port)


Data is stored with a Date/Time stamp, Station ID and a sequential weld count number

Graphic 256x64 pixel display
Compact NEMA 12 rated enclosure
Internal Non-Volatile memory to store up to 4,000 welds summaries
Ability to send data to external printer for hard copy with software selectable print format for 80 or 40 column printers
Configurable for English or Metric units
Ethernet port for remote data uploads using Modbus TCP/IP protocol or USB port for PC serial communications with Modbus RTU protocol
Chance of error in recording data eliminated
Easily transportable between plants or shop locations (ideal for inspectors)
Instantaneous viewing of current welding conditions (ideal for inspectors)
Permits extended data logging without need for printer at location (ideal for inspectors and welding engineers)
Ability to collect and display run time welding data using PC and optional ArcTrack II software
Ability to generate printed hard copy at job site or back at office location ideal for inspectors)

Data Logging: Welding parameter data can be dumped to an external printer for hard copy printout and fault analysis or to a PC using ArcTrack II software for data storage and analysis.
Mean and standard deviation for each parameter
Graphic analysis for single and multiple weld data files

The optional ArcTrack II program is designed to use the various CWT Weld data sensors and provides advance data logging function. It is designed to provide a simple GUI interface for weld data logging for manual weld procedure development and documentation. It provides a Sweep chart option to graphically monitor and collect welding data from remote CWT Sensors. It provides both run time and summary data files that can be directly imported into Microsoft Excel for further evaluation. This program can be used with the following CWT sensors; Micro ADM, Intella-DART, WireTrak, Smart Sensor, GFM and the WDL-3.

The sensor provides fault testing of the basic welding parameters (i.e. Volts, Amps, Wire Speed, Gas Pressure and Arc Time). It incorporates an advanced testing algorithm that provides three levels of fault testing. The sensor provides in-process parameter limit testing, Arc Density (AAD) for each weld in a Part and an ADD, Weld Count and Volume Applied test for each Part. The sensor also features a Part Learn Mode that allows the sensor to establish statistical control limits based on actual production parts. The ArcTrack II™ program allows the user to upload run time weld data and stored SPC weld summary data.
