THE DIAGRAM SHOWS ELECTRODE CONNECTED POSITIVE. TO CHANGE POLARITY, TURN POWER OFF, REVERSE THE ELECTRODE AND WORK LEADS AT THE

POWER SOURCE, POSITION THE POSITIVE-NEGATIVE SWITCH ON THE POWER SOURCE TO CORRESPOND TO THE POLARITY OF THE ELECTRODE CABLE CONNECTION. REFER TO NA-5 OPERATING MANUAL FOR REQUIRED NA-5 CONTROL BOX POLARITY CONNECTIONS.

N.A.

WELDING CABLES MUST BE OF PROPER CAPACITY FOR THE CURRENT AND DUTY CYCLE OF IMMEDIATE AND FUTURE APPLICATIONS.

N.B.

EXTEND LEAD 21 USING #14 OR LARGER INSULATED WIRE PHYSICALLY SUITABLE FOR THE INSTALLATION. AN S-16586-[ ] REMOTE VOLTAGE-SENSING WORK LEAD

 

IS AVAILABLE FOR THIS PURPOSE. CONNECT IT DIRECTLY TO THE WORK PIECE KEEPING IT SEPARATE FROM THE WELDING WORK CABLE CONNECTION TO

 

WORK PIECE. FOR CONVENIENCE, THIS EXTENDED #21 LEAD SHOULD BE TAPED ALONG THE WELDING WORK CABLE.

N.C.

TAPE UP BOLTED CONNECTION.

 

 

 

N.D.

CONNECT THE NA-5 CONTROL CABLE GROUND LEAD TO THE FRAME TERMINAL MARKED

 

 

 

NEAR THE POWER SOURCE TERMINAL STRIP. THE POWER SOURCE

 

MUST BE PROPERLY GROUNDED.

 

 

 

N.E.

IF USING AN OLDER AUTOMATIC CONTROL CABLE WITH LEADS 75, 76, 77; CONNECT LEAD 75 TO #75 ON TERMINAL STRIP, CONNECT LEAD #76 TO #74 ON TERMINAL

 

STRIP, CONNECT LEAD #77 TO #73 ON TERMINAL STRIP.

 

 

 

N.F.

CONNECT THE JUMPERS ON THE NA-5 VOLTAGE BOARD AS FOLLOWS: CONNECT RED JUMPER TO PIN "S". CONNECT WHITE JUMPER TO PIN "B".

N.G.

SET THE DC-1000 OR DC-1500 CONTROLS AS FOLLOWS: SET THE CONTROL SWITCH TO "OUTPUT CONTROL REMOTE".

 

FOR SUBMERGED ARC PROCESSES, SET THE MODE SWITCH TO "C.V. SUBMERGED ARC". FOR OPEN ARC PROCESSES, SET THE MODE

 

SWITCH TO "C.V. INNERSHIELD"

 

 

 

N.H.

FOR PROPER OPERATION, THE ELECTRODE CABLE MUST BE SNUGGED UNDER THE CLAMP BAR ON THE LEFT SIDE OF THE NA-5 CONTROL BOX.

N.J.

TERMINALS #73 AND #74 WERE NOT PRESENT ON DC-1500 MACHINES BELOW CODE 8294. THESE EARLIER CODE MACHINES ARE NOT SUITABLE FOR

 

USE WITH THE NA-5.

 

 

 

N.K.

ALTERNATIVE 500 AMP POSITIVE TERMINAL CONNECTION PROVIDED ON DC-1000 MODELS ABOVE CODE 9500 ONLY.

N.L.

ALTERNATE SUBMERGED ARC MODE AVAILABLE FOR IMPROVED ARC STABILITY IN HIGH CURRENT, LARGE PUDDLE, SLOW TRAVEL PROCEDURES BY MAKING

 

SPECIAL CONNECTIONS ON BOTH DC-1500 AND NA-5.

 

 

 

 

ON DC-1500 CONTROL BOARD (G-1530-2 AND SUPERSEDING) REMOVE RED AND BLUE JUMPERS FROM "FR" PINS AND RECONNECT TO CORRESPONDING "SR" PINS.

 

ON NA-5 VOLTAGE BOARD (G-1556-1 AND SUPERSEDING) WHITE JUMPER MUST BE CONNECTED TO PIN "D".

 

NA-5 PIN "D" CONNECTION MAY ALSO BE USED FOR SOME PROCEDURES ON DC-1500 WITHOUT CONTROL BOARD JUMPERS, DC-1500 WITH CONTROL BOARD

 

JUMPERS ON "FR" PINS OR DC-1000.

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.
