Designing a Wire Delivery System

Designing a Wire Delivery System – 8 Steps

The following steps are designed to help guide you through the basics of setting up and optimizing a wire delivery system.

  • What is the wire type?
  • What is the wire diameter?
    • These two questions will help determine the appropriate conduit and size
  • Will the welding be done robotically?
    • If so, is the main wire feed motor mounted on the robot arm or in a fixed (non-moving) position?
  • Is the welding a semi-automatic welding application?
    • If so, will the feeder be mobile such as on a swing boom, or on a power-source that is moved around the welding area?
  • Is this a fixed automation application?
    • If so, does the feeder move or is it stationary?
  • Where will the weld wire package be placed?
  • Is the package in a direct line with the main feed motor during the weld process, or will it be offset?
    • Every bend radius and plane change in a conduit run will add skid friction coefficient.
  • Are obstacles interfering that will cause tight radial bends or multiple bends and plane changes in the conduit unless avoided?
    • Power sources, controllers, overhead cranes, gas piping, parts supply totes, torch maintenance equipment, home position of a robot / weld system, can all influence the layout and parts needed in a wire delivery system.

DETERMINING FACTORS FOR CONDUIT SELECTION:

  • Wire Type and Composition
  • Wire Diameter
  • Application
  • Single conduit run or dual conduit run (static to dynamic)
  • Distance wire is traveling

WIRE TYPE & COMPOSITION

  • Solid Carbon MIG Wire — any conduit material of appropriate I.D. for wire size.
  • Cored Wires — any conduit material of appropriate I.D. for wire size.
    • Metal lined conduits generally allow greater longevity than a polymer conduit.
  • Aluminum — green polymer conduits or flexible steel conduits lined with a polymer liner.
  • Stainless Steel Wires — any conduit material of appropriate I.D. for wire size.
    • Green polymer conduits are optimal if ferrous contamination is of concern.
  • Silicon Bronze — green polymer conduits or flexible steel conduits lined with a polymer liner.

WIRE DIAMETER

  • .030″ (0.8 mm) diameter and smaller wires use the FC-X-SW or EC-3-R conduits.
  • .035″ – .052″ (0.9 mm – 1.3 mm) diameter wires use EC-4-R, FC-X, or FC-E conduits.
    • These three conduits are optimal for the majority of high-volume welding applications in the industry.
  • .062″ – 1/8″ (1.6 mm – 3.2 mm) diameter wires use EC-5 or FC-XH conduits.
  • 1/8″+ (3.2 mm+) diameter wires use EC-6 or FC-XH-LW.
    • These wire sizes are used in submerged arc (SAW) applications, see our SAW Wire Delivery Equipment section on our website for large wire delivery products

APPLICATION

  • Static Application — use of the EC line of green polymer conduits is optimal.
  • Dynamic Application — use of the Flexible line of Wire Wizard conduit is recommended.
    • EC-3-R and EC-4-R conduits are suitable for flexible applications as well.
  • Hybrid Application — use of both the EC line of green polymer conduit and Wire Wizard Flexible Conduits.

Ready to choose your conduit?

  • All male bayonets fit all female quick disconnects.
    • Male bayonet conduit connectors are tapered for ease of feeding and to reduce wear points.
    • Available compression connectors with attached strain relief support the weight of conduits to prevent added weight on connection point and potential re-casting of wires.

POLYMER CONDUIT CONNECTORS

  • Self-threaded connectors easily connect for a snug fit on static applications. They also can be removed and re-used on a new piece of conduit.
  • Compression connectors offer a tight and locked connection. Bayonet and nut can be re-used with a new replacement ferrule. Used in dynamic conduit applications.

FC-X CONNECTORS

  • Compression connectors offer a tight and locked connection. Bayonet and nut can be re-used with a new replacement ferrule. Used in dynamic conduit applications.
  • Hydraulically swaged connectors are a permanent connection and only available in pre-cut lengths that have been assembled at Wire Wizard.

FC-E CONNECTORS

  • Compression connectors offer a tight and locked connection. Bayonet and nut can be re-used with a new replacement ferrule. Used in dynamic conduit applications.
    • Reinforcement tube required in conduit I.D. when using a compression connector.
  • Hydraulically swaged connectors are a permanent connection and only available in pre-cut lengths that have been assembled at Wire Wizard.

  • Who is the wire feeder manufacturer?
  • Is the feeder inlet a slip fit-thru hole with set screw or is it a threaded connection?
    • If a threaded connection, is it a male or female threaded connection?
    • If threaded, knowing the thread count is also very useful information.
