KP3937-1 - Lincoln Viking PAPR Standard Lithium-Ion Battery Pack (8-9 Hour Run Time)

Reliable Power for Your Viking PAPR System

When you are deep in a weld and the shop air is thick with fume, the last thing you want to worry about is your respirator dying. The Lincoln Electric KP3937-1 Standard Battery Pack is the heartbeat of your Viking PAPR system, designed to keep clean air flowing so you can focus on laying perfect beads. Built with modern lithium-ion technology, this battery packs a serious punch in a lightweight package. It offers up to 9 hours of run time on a single charge, meaning you can clock in, work a full shift, and clock out without ever needing to swap batteries or stop for a recharge. It is the kind of reliability professional welders demand.

Comfort is king when you are wearing gear all day. Old-school batteries were heavy and bulky, dragging down your belt and straining your back. The KP3937-1 weighs in at just under a pound (13 oz), making it incredibly light for the power it delivers. You will barely notice it is there, but you will definitely appreciate the fresh air it powers. The lithium-ion chemistry also means you don't have to drain it completely before recharging—top it off during lunch or between shifts without worrying about ruining the battery's lifespan. It is rated for over 500 charge cycles, giving you years of dependable service.

We always recommend keeping a spare KP3937-1 in your kit. While one battery covers a standard shift, overtime happens, and forgetting to charge your gear happens to the best of us. Having a backup charged and ready ensures you never have to revert to a passive helmet or compromise your safety just because of a dead battery. This is a genuine Lincoln Electric part, built tough to withstand the heat, sparks, and grime of the welding shop. Simply click it into your blower unit, and you are ready to breathe easy and weld hard.
