Centerfire™ Consumable System


Bernard developed its Centerfire™ Consumable System with the user's cost considerations in mind. Our contact tips, nozzles and diffusers are easy to use and high performing – they provide better arc starts, less spatter and more consistent welds – and also last up to three times longer than competitive brands.

All consumables are not created equal.
From materials to cost and design quality, each brand on the market varies and so does their performance. In fact, comparing consumable quality and costs to the amount of labor for changeover and rework often reveals surprising results – less expensive consumables don't always add up to cost savings.
