Key Technical Features

This model is rated at 400 Amps at 100% duty cycle when using CO2 shielding gas, and 60% duty cycle with mixed gases. This high duty cycle makes it ideal for high-volume production environments where equipment needs to run continuously without overheating. The gun utilizes the Universal Conventional Liner, which is designed to minimize friction and wire chatter, ensuring a stable arc and consistent bead profile.

Centerfire Consumable System

The S4015MC3CMC comes equipped with Bernard's Centerfire consumables. The unique design of the Centerfire tip allows it to be rotated 360 degrees to create a fresh wear surface, extending the life of the tip before replacement is necessary. The spatter shield within the nozzle protects the diffuser and ensures smooth gas flow, while the threadless design prevents tips from seizing in the gun head.

Ergonomics and Durability

Featuring the S-Series handle, this gun offers a slim, comfortable grip that allows for precise manipulation of the torch. The trigger is designed to withstand over one million cycles, ensuring longevity even in the harshest conditions. Additionally, the armored neck and rugged cable jacket resist cuts, burns, and abrasion. For welders who demand the best in terms of uptime, comfort, and weld quality, the Bernard BTB 400A gun is the superior choice.
