PowerBall® Torch Liners provide a simple and cost-effective way of boosting the performance of existing robotic and semi-automatic MIG Guns. By reducing wire skid friction, wire vibration and wire shaving, they can provide instant results with improved welding quality, consistency and smoother wire delivery. The additional durability and reduced wire friction also makes these torch liners ideal for cored wire applications, as these wires are more abrasive than solid steel wire used in GMAW.

• Elliptical wire liner with proprietary coating reduces skid friction and eliminates wire shaving
• 72% LESS wire skid friction vs. round wire liner (as tested with .045 wire @ 175 IPM / 15' liner)
• Long life due to less friction and reduced wear
• Reduces wire vibration that can cause arc failures and poor welding consistency
• Replacement liners available for most robotic and semi-automatic torch brands, including: Lincoln Electric®, Abicor Binzel®, OTC®, Fronius®, American Weldquip®, Tregaskiss®, Panasonic®, Bernard® & Tweco® - Click here for a full list of replacement liners available
• American-made and in stock!

The Wire Pilot® Pneumatic Wire Feed Assist (aka PFA), along with the Wire Guide Module System, is the most effective way to eliminate wire skid friction inside the conduit. This is especially critical with aluminum wire, longer distance runs to the feeder, and larger diameter wires used in submerged arc welding. When adjusted properly, the Wire Pilot® Feed Assist can eliminate birdnesting, excess wire friction, burn-backs and more. Here are three quick tips to fine tune the PFA for optimum wire delivery performance:

Drive Roll & Wire Alignment
When first setting up the Feed Assist and after each wire changeout, it is critical that the drive rolls are aligned for proper gear alignment. Otherwise, they will not rotate in sync, and can cause feeding issues and drive roll slippage. Additionally, just like with a wire feeder, it is important the wire is fed through the grooves in the drive rolls and so it is not being crushed by them.

Proper Air Pressure Adjustment
In most applications, the Feed Assist requires a surprisingly low amount of air pressure (often 5 PSI or less – more for larger diameter wires). This varies based on the wire size, type and length of run to the feeder. Supplying too much air pressure is one of the most common mistakes made when setting up the Feed Assist, however it is easily resolved. Simply back down the air pressure, then slowly turn it up until the PFA just begins pushing wire through the conduit. Perform the following "pinch test" to ensure proper setup:

Adjusting the Drive Roll Tension
If the drive rolls are slipping and not pushing the wire, this is a clear sign the drive roll tension is too loose and needs to be adjusted. It can also be too high if the wire is getting crushed or stuck between the drive rolls. The drive roll tension is easily adjusted using the tension knob on the Feed Assist, and should be either tightened or loosened in short ¼ to ½ turns until the Feed Assist successfully passes the pinch test mentioned above.
