    OK AristoRod is a amily o non copper-coated GMAW wires with superior welding

    perormance. The unique Advanced Surace Characteristics (ASC) increase

    perormance and eciency, whether the process is manual, mechanized,

    or robotic, helping reduce overall welding costs.

    OK AristoRod non-copper-coated wires do not contaminate wire eeders, liners,

    torches and contact tips with copper particles. This results in trouble ree eeding,

    high process stability, reduced consumption o wear parts, and superior welding

    properties.

    The unique eatures o OK AristoRod translate into clear user benets which,

    together, add up to increased productivity and lower welding costs.

    To get the most benet rom using OK AristoRod welding wires, there are someimportant steps to keep in mind, in particular compared to using copper-coated

    wires. This guide provides practical step-by-step inormation on how to install and

    use OK AristoRod non-copper-coated solid wires.

    To ully beneft rom the excellent weldability o OK AristoRod GMAW

    wires, the welding equipment needs to be maintained in good condition.

    The ollowing checklist serves as a guide.

    cn t an g Nzz

    Remove spatter and replace worn or

    damaged contact tip.

    For the best welding performance and

    longest tip life, ESAB contact tips are

    recommended for use with

    OK AristoRod wires.

    Grind the end of the liner conical for

    optimal fitting of the contact tip.

    Ensure that the contact tip is the correct

    size and fits tightly.

    Ensure the gas nozzle is free from

    spatter.

    correct incorrect

    For contact tip sizes and packages, please contact ESAB or your local Distributor.

    Spiral steel liners are recommended.

    Never use liners which have been

    used for copper-coated wires.

    Copper residuals may stick onto the

    OK AristoRod wire and deteriorate itsexcellent wire feeding.

    Ensure that the liner has the correct

    inner diameter for the wire size to be

    used.

    Check liners regularly for kinks and

    excessive wear and replace when

    needed.

    Clean liners regularly using compressed

    air, removing the contact tip first.

    g n w

    Check gas and water connectionsfor leaks.

    Check that the water cooler is filled and

    that the pump is operating effectively.

    w un

    Position wire guide tubes as close aspossible to the rollers to prevent kinking

    of the wire.

    A substantial amount of fine metallic

    shavings underneath the drive rolls

    indicates misalignment.

    Step 6. Attach the wire conduit to the wire feeder.Avoid liner bends or point pressure on the liner.

    Step 1. Remove the rubber strap and VCI paper.

    Step 4. Place the carton or plastic lid (Standardand Mini Marathon Pac) or cone (JumboMarathon Pac) on top of the Marathon Pac.

    Step 2. Place the wire conduit attachment orspider on top of the Marathon Pac.

    Step 5. Attach the wire conduit to the lid or conewith the quick connector.

    Step 3. Feed the welding wire through the centreof the spider.

    Use drive rolls with smooth, double

    V-grooves. U-shaped grooves or knurled

    rolls may damage the welding wire

    surface.

    Check that the groove size is correct for

    the wire diameter.

    Apply the correct pressure on feed rolls.

    Too much pressure flattens the wire,

    resulting in feeding problems and higher

    liner and contact tip wear. Insufficient

    pressure may cause wire to slip in the

    feed rolls, resulting in irregular feeding

    and possible wire burnback.

    A good approach is to set the roll

    pressure so it is possible to stop a bent

    wire at the gas nozzle by applying light

    pressure.

    Check that the wire is feeding correctly

    from the contact tip.

    Never use felt pads or liquids to clean

    the wire surface. This may damage

    the advanced surface condition of

    OK AristoRod wires.

    Check that the appropriate gas is used.

    Adjust gas flow rate to between 0.5-0.7

    cfm (15-20 l/min) or according to gas

    nozzle size.

    Check the gas flow rate again if the gas

    nozzle diameter is changed. Always

    check the gas flow on the gas nozzle

    as well.

    It is essential to t the gas nozzle and

    contact tip at the right distance relative

    to each other. The ideal distance o the

    contact tip is 0.080 in. (2 mm) recessed.

    A longer distance will orce the welder to

    use too long a stick-out, resulting in poorweldability. This may lead to lack o usion,

    particularly in narrow joints. Contact tips

    protruding beyond the gas nozzle can

    result in insucient gas shielding.

    c sk-o ln

    The stick-out is the distance between the

    contact tip and workpiece and must be

    kept between 1/2 in. and 3/4 in. (12 and

    20 mm ) 0.040 in. and 0.047 in. ( 1.0

    and 1.2 mm). Excessive stick-out results

    in too short an arc length, larger droplets,

    an unstable arc and spatter leading to poor

    weldability. Additionally, it may reduce the

    gas protection which can lead to porosity.

    When welding in spray arc with too short o

    a stick-out, the arc length can become too

    long. The weldpool will get hotter and more

    dicult to control.

    Incorrect. Contact tip too recessed.

    Incorrect. Contact tip protruding beyondgas nozzle.

    2 mm

    Correct positioning of contact tip.

    1/2 - 3/4 in. (12-20 mm)

    Ideal stick-out for wire diameters 0.040and 0.047 in. (1.0 and 1.2 mm.).

    Various nozzle diameters must be available

    to allow adequate access to the joint, to

    maintain the above recommended stick-

    out, and to ensure proper shielding gas

    protection. Small diameter gas nozzles

    are used or the rst layers only. Revert to

    the standard gas nozzle diameter when

    access to the weld joint allows, so ull

    gas protection can be assured.

    Incorrect. Use of standard gas nozzlerestricts access to narrow joints, resultingin too long a stick-out.

    Correct. Use a smaller diameter nozzle ora conical nozzle for the 1st layers in theroot area.

    Correct. Use of standard gas nozzle forcompleting the joint ensures good gasprotection and correct stick-out.

    When welding in short arc transer, the arc stability and start properties will improve

    when reducing the stick-out.

    Incorrect. Arc length too long. Arc becomestoo wide, with insufficient penetration. Also arisk of burnback to the contact tip. This maybe caused by the arc voltage being too high,the wire feed speed too low or the stick-outbeing too short.

    Use positive polarity or OK AristoRod

    solid welding wires. A given welding current

    requires a specic arc voltage or optimum

    weldability. The welding current is set by

    adjusting the wire eed speed control. The

    arc voltage is regulated by the open circuit

    voltage (OCV) setting o the power source.

    h g n o sn

    For the ollowing procedure, it is critically

    important to keep the stick-out constant

    within the correct range or each welding

    position.

    Select a welding current which suits your

    application from the graph on page 12.

    Start welding with the lowest voltage

    value from the given range. This may

    result in stubbing, however wireburnback will be avoided.

    Increase the arc voltage in steps of 1

    or 2 V until the arc becomes stable,

    smooth and spatter free, with a slightly

    crackling sound. Ensure the correct

    stick-out length is maintained.

    wn p sn

    Correct. Correct arc length. Stable andconcentrated arc with a quiet spray droplettransfer.

    Incorrect. Arc length too short. Wire dipsinto weld pool (stubbing) caused by too lowan arc voltage, too high a wire speed or toolong of a stick-out.

    wn p sn

    Note: As mentioned, stick-out control is very important. I the recommended

    stick-out length is not constantly maintained, weldability will fuctuate. Shortening

    the stick-out will result in an increasing current and a longer arc. Lengthening thestick-out will result in a lower current and the arc being too short.

    Due to OK AristoRods Advanced

    Surface Characteristics (ASC) the

    optimal voltage is typically 5-10%

    higher than with a copper-coated

    wire at the same arc length.

    If a different current is required,

    i.e change of welding position, the

    procedure described on the previous

    page needs to be repeated.
