    Small, Robust, Flexible & Complete

    The LF33S wire feeder is designed to withstand the most extreme environmental conditions. These machines 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 LF33S 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
    • 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.

    What does a separate wire feeder do with a constant voltage power source?icon-minus-redicon-plus-red

    With a constant voltage (CV) power source you set the voltage on the power source, and the wire feed speed, which largely controls the welding current, is set on the wire feeder. A constant-speed feeder is the usual partner for this type of power source. The feeder also carries the wire spool, drive rolls and torch connection, so it can sit close to the job while the power source stays put.

    A voltage-sensing feeder is a different design, so check that any feeder you choose is intended for your power source type and connections.

    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.

    What causes bird nesting at the wire feeder?icon-minus-redicon-plus-red

    Bird nesting is a tangle of wire at the drive rolls. It usually happens when the wire is blocked further along and the rolls keep pushing. Common causes are a liner that is cut too short, too tight for the wire, dirty or damaged, a contact tip that is worn, blocked or burnt back, drive rolls of the wrong size or type, and tension set too high.

    Check the feeder first, then work towards the torch. Inspect the rolls and guides, then try pulling the wire through the torch by hand with the tension released. Heavy drag points to the liner or tip. Keep the torch cable as straight as practical while welding.

    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.
