Easily installed procedure and timer boards to permit adjustment of wire speed and voltage. Can be installed to function at either the start of the weld or at the end for crater filling. Installation, operating, and maintenance instructions are shipped with each kit and can be ordered as Sec. T2.5.13 K334.

K336 REMOTE INTERFACE MODULE

Permits connection of customer-furnished remote start-stop and inch momentary contact closure or momentary 24 volt signals. Also used when a single remote signal is desired to start or stop multiple heads. This module replaces the earlier K336 Remote Pushbutton Interface Module. Installation and application instructions are shipped with each kit and can be ordered as Sec. T2.5.11 K336.

The current relay is useful to fixture builders and others who need a signal indicating that welding current is flowing. Installation, operating, and maintenance instructions are shipped with each kit. The S22022 relay module is suitable for dry circuit applications and it is rated at 2 Amps, 115 VAC or 28 VDC. This relay has both normally open and normally closed contacts. The S22182 relay module is suitable for applications requiring at least 10 mA current and it is rated at 3 Amps, 115 VAC or 28 VDC. This relay only has normally open contacts.

SPEED-FEED DRUM

These drums must be set on a turntable which permits them to freely turn in a clockwise direction. Installation, operating, and maintenance instructions are contained in the IM305 manual and can be ordered as Sec. T2.5.7-A.

Permits setting of weld time for an adjustable period. Eliminates need to press the “Stop” button. Instructions are included in the kit.

K349 MULTI-PROCEDURE KIT

The K349 Multi-Procedure Kit provides three additional weld mode procedure settings of wire feed speed and voltage, allowing the choice of four NA-5 weld mode procedures. Installation, operating, and maintenance instructions are shipped with each kit, are contained in the IM305 manual, and can be ordered as Sec. T2.5.19 K349.

These reels require dereeling equipment that permits the reel to rotate freely as the electrode is used. Installation, operating, and maintenance instructions are contained in the IM305 manual and can be ordered as Sec. T2.5.7-B.

NA-5S, NA-5N, NA-5SF, NA-5NF specifications

The Lincoln Electric NA-5NF, NA-5SF, NA-5N, and NA-5S are advanced welding helmets that are pivotal in enhancing the safety and efficiency of welders in various applications. These models are designed to provide exceptional protection and visibility, making them indispensable tools in the welding industry.

One of the main features of the NA-5 series is the auto-darkening filter technology. This feature allows the helmet to automatically adjust its shade based on the intensity of the arc. As the welder strikes an arc, the lens darkens instantaneously, shielding the eyes from harmful rays generated during the welding process. This functionality not only ensures safety but also enhances productivity, as welders do not need to manually flip the helmet up and down.

The helmets are equipped with a wide viewing area that allows for better visibility and precision while working. With a large lens, welders can easily monitor their work and surrounding environment, minimizing the risk of accidents. Additionally, the lightweight design of the NA-5NF, NA-5SF, NA-5N, and NA-5S provides comfort during extended periods of use, reducing neck strain and fatigue.

The NA-5 series is also well-regarded for its durability. Constructed from impact-resistant materials, these helmets can withstand the rigors of demanding work environments. This durability extends the lifespan of the helmet, making it a cost-effective investment for both professional and hobbyist welders.

Another notable characteristic is the adjustable sensitivity and delay settings found in certain models. These settings allow the user to customize the helmet based on their specific welding conditions. For instance, a welder can increase sensitivity for low-amperage tasks or adjust the delay to allow for a smoother transition from dark to light after completing a weld.

Furthermore, the helmets come with a reliable battery life, ensuring that they can be used for long periods without interruption. Some models also feature solar assist functionality, which helps recharge the auto-darkening filter, enhancing their overall efficiency.

In summary, the Lincoln Electric NA-5NF, NA-5SF, NA-5N, and NA-5S welding helmets represent a significant advancement in personal protective equipment for welders. Their combination of auto-darkening technology, wide viewing area, lightweight design, durability, and customizable settings makes them an excellent choice for anyone engaged in welding tasks. With these helmets, users can achieve greater safety and efficiency in their work, enabling them to focus on their craft with peace of mind.
