    Small, Robust, Flexible & Complete

    The LF33 wire feeder is designed to withstand the most extreme environmental conditions. These machines glorify focus on their ruggedness construction, physical dimensions, and ease of use to stand out from the pack. The result is an exceptionally rugged, protective casing as standard complete with undercarriage to use under tough industrial conditions. The LF33 can accept not only D300 (15Kg) but also small D200 (5Kg) wire spools, using solid or cored wire. The wire feeder is equipped with 2/4-step, run-in, wire inch, gas purge and two clear digital meters that display the welding voltage and amperage.

    Features

    • Small, rugged, and easy to handle with bright digital Volt and Ammeter
    • Excellent wire drive system with four large drive rolls and a powerful motor
    • An electronic feedback system on the wire drive will guarantee consistent wire feed speed
    • Features Burnback, cold feed/gas purge, spot welding, meters, 2/4 stroke

    Lincoln CV-425 Options FAQs

    Optional extras for a constant voltage MIG power source: remote wire feeders, torches, water coolers and interconnecting cables, and how to match them.

    Should I choose a two-roll or four-roll wire feeder?icon-minus-redicon-plus-red

    Both can feed wire well; the choice depends on the wire and the job. Two rolls suit small, hard steel wires and are also best for soft wires such as aluminium, where heavy drive pressure can crush the wire. Four rolls are better for larger hard and flux-cored wires, long torch cables and wire supplied in large packs, because the first set of rolls helps straighten the wire and the second smooths feeding.

    Look at the wire sizes and types you plan to run and the torch cable length before deciding, and check the power source and feeder manuals for what the feeder is designed to take.

    How do I choose the right drive rolls for my wire?icon-minus-redicon-plus-red

    Drive rolls must match both the wire diameter and the wire type. As a general guide, smooth V-groove rolls suit solid steel and stainless wire, knurled (sometimes called V-knurled) rolls suit flux-cored wire because the teeth grip the soft tubular wire without heavy pressure, and U-groove rolls suit soft aluminium wire. Names and recommendations vary, so check the wire maker's and feeder maker's recommendations.

    A roll of the wrong size or type can slip or deform the wire, and the wrong roll can shave the wire and fill the liner with debris. Inspect the rolls each time you fit a new spool.

    How tight should the drive roll tension be?icon-minus-redicon-plus-red

    Only as tight as needed to push the wire through the torch without slipping. Too much pressure can flatten or deform the wire, which can cause feeding problems further along, and if the wire path is restricted it can lead to a bird's nest at the rolls. Cored and aluminium wires are especially easy to deform.

    A widely used method is to release the tension, feed wire against a gloved hand or a block of wood, then tighten gradually until the wire stops slipping, adding only a little more. If the maker gives a setting method for your feeder, follow that. Never put your fingers near the rolls while the feeder is live.

    Does a longer interconnecting cable affect the weld?icon-minus-redicon-plus-red

    It can. Longer cables add resistance, which causes voltage drop, so the voltage at the arc may be lower than you set. Signs include a short, tight or stuttering arc, hot cable connections or crimps, and having to keep raising the voltage. Turning the voltage up only hides the cause.

    To limit the effect, use leads sized for the current, upsize them on long runs, keep every connection clean and tight, and avoid unnecessary joins. Count the whole circuit, because the work lead is part of it. Keep long cables straight rather than coiled, and use the cable sizing information in the power source manual.
