Technology has pushed us into thedigital era. From video cameras tophones, “digital” is replacing “analog”.Why?

Digital Communications allow forfaster, more dependable, moreeconomical equipment performance.Historically, welding system performance has been limited by theanalog circuitry that controlled it.Analog signals can only be transmittedover limited distances, as the signalsattenuate or “die out” over longerdistances, compromising data integrityand limiting the cable distancesbetween welding system components.

Digital Communications promote fastersignal transfer, while preserving dataintegrity and simplifying wiring. A digitalprotocol also provides a scalableframework for future upgrades, whichallows engineering changes to bemade through software upgradesinstead of module replacements.Digital Communications speed up datatransfer rate and minimize delay,enhancing welder performance.

SPEED OF PERFORMANCEDelays are reduced, allowing more data to be transferred in less time.

FLEXIBILITY/SCALABILITYNew features can be added to existing equipment through software upgrades,and new components can easily be added to an existing welding cell.

COST REDUCTIONA single cable between multiple devices is less expensive and more efficient.

SIMPLIFIED EQUIPMENT MAINTENANCECalibration between the power source and robot is not necessary, even afterfeatures are added to an existing system.

PROCESS CONTROLSAll weld process controls are accessible from a single user interface controlpanel.

PRODUCTION MONITORINGHigh-speed communications enable the use of software tools to trackequipment usage and condition, allow configuration of limits and responsesafter each weld, and provide storage of thousands of weld summaries.

ArcLink is the leading digitalcommunications protocol forthe arc welding industry. Itintegrates all weldingcomponents for seamless, time-critical data transfer.The strength of ArcLink liesin the ability to communicatewith each system componentin a pre-defined weldinglanguage. In addition,ArcLink is an opencommunications protocol,meaning that Lincoln Electricpublishes how it works andencourages other companiesto adopt it.

ArcLink brings modularity towelding systems and providesa single, intelligent connectionbetween all modules. AnArcLink network can be assimple as a single stickwelder or as complicated asrobotic installations.

The ArcLinkcommunications protocolserves two purposes:as the native device language in Lincoln Electric welding systemcomponents, and as the interface for robotic welding applications. ArcLinkalso allows for networking capabilities through gateways (such asEthernet) to allow simultaneous monitoring of multiple welding cells, whichestablishes a means for developing supervisory or monitoring tools.

HowArcLink Works

ArcLink uses peer-to-peer, event-driven messaging, which broadcasts on an “as-needed” basis. Peer-to-peermessaging frees space on the data highway, reducing message traffic. Because ArcLink logic is based on aController Area Network (CANIIB) standard, it inherits the benefits of priority-based, deterministic messaging andnoise immunity. This means that critical messages are guaranteed to reach their destination with minimum delay,even in the presence of electrical noise. The ArcLink cable houses five conductors as depicted below.

5-pin ArcLink Connector

Leads D and E arededicated powerleads supplying 40 VDC, enoughpower to run the wirefeeder drive motor.This eliminates theneed for a separate wire feederpower cable.

Leads A and B are dedicated tocommunications. They carryCANIIB messages between weldingsystem components.

Lead C serves as the voltage sensory lead.Lincoln Electric digital welding machinessupply this lead within the ArcLink cable.Certain applications may require anadditional voltage sense lead.

BenefitsOf Using ArcLink

Modular System Configuration• Allows for creation of custom welding

HowDeviceNet Works

DeviceNet connectivity is established through a DeviceNet Gateway. DeviceNet carries data from thecomponents of the welding systems (slaves) to a Programmable Logic Controller (master). DeviceNetperforms deterministic messaging, so that all messages are assigned priorities, preventing interference ordestruction of important data. The DeviceNet connector houses five conductors, as depicted below. Becauseit only carries 24 VDC, an additional cable is required to power the wire feeder drive motor. Additionally, thiscable does not contain a voltage sensing lead.
