Miller Bernard® BTB Series Air-Cooled MIG Welding Gun
An air-cooled MIG welding system relies solely on the ambient air and shielding gas to dissipate heat that builds up along the length of the welding circuit. Air-cooled systems use much thicker copper cabling than water-cooled systems, which allows the cable to transfer the electricity to the gun without building up excessive heat from electrical resistance. Industrial-grade BTB semi-automatic air-cooled MIG guns are engineered to accommodate each welder's neck, handle and trigger preferences for increased weld access, comfort and productivity.
Features
Multiple handle and trigger options -
- Choose between seven different curved and straight handle styles,
- Wide selection of handles and easy-to-change trigger options allow guns to be matched to user preference and welding application.
Fixed or rotatable necks -
- Wide variety of angle and length options,
- No tools required to adjust rotatable necks.
High-performance consumables-Choose from new AccuLock™ S, Centerfire™, Quik Tip™ or TOUGH LOCK® consumables.
AccuLock™ S liners-Bernard® BTB Series can all be supported with a common line of high-performing consumables – including new AccuLock™ S liner – which simplifies ongoing maintenance and inventory costs.
Centerfire™-Centerfire™ 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.
Quik Tip™-Bernard Quik Tip™ consumables are designed with a threaded taper lock between the contact tip and the gas diffuser that increases tip life by providing excellent heat transfer and electrical conductivity.
TOUGH LOCK®-TOUGH LOCK contact tips are manufactured from high-quality, high-conductivity copper using a mandrel-drawn process that controls tip tolerances. When mated with our TOUGH LOCK retaining heads, they produce lower contact tip temperatures.
Durable unicable design-Choose Hytrel® polymer cable (industrial grade), or upgrade to steel monocoil cable for extra pinch/kink resistance.
Liner options-Choose between new AccuLock S liners for a flawless wire-feed path and error-proof liner replacement, Bernard conventional liners, front-loading QUICK LOAD® liners or the QUICK LOAD liner AutoLength™ system.
QUICK LOAD® liners-Innovative QUICK LOAD® liners install from the front of the MIG gun in less than half the time required to install conventional liners, increasing uptime, cost savings and safety.
Patented Jump Liner-allows quick neck change and replacement of only most commonly worn or clogged liner area, which reduces the amount of time a gun is offline and minimizes inventory.
Back end with durable rigid strain relief-and easily interchangeable direct plugs and trigger leads connect to wire feeders and machines from major manufacturers and allow simple maintenance.
