How to install AccuLock S liners?

• Remove the nozzle of the welding gun.
• Loosen the gas diffuser and remove it from the gun.
• Lossen the set screw in the power pin cap and remove the cap from the rear of the gun.
• Now remove the old liner and replace it with a new liner through the neck.
• Keep the gun straight and push the liner through until the brass liner lock bottoms on the neck.
• Now, lock and centre the liner by reinstalling and tightening the gas diffuser.
• Reinstall the nozzle.
• Place the power pin cap over the liner and thread it onto the power pin.
• Tighten the cap that is snug against the power pin shoulder with welding pliers or an appropriate wrench.
• Trim the liner flush with the power pin.
• Finally, insert a piece of welding wire onto the liner to check for burrs or obstructions. If needed loosen the screw slightly until the wire slides freely.

What items are included in TOUGH LOCK consumables?

• Retaining Heads: These units mate with contact tips to minimise contact tip temperature due to increased surface contact.
• Contact Tips: These tips are made of high-quality and highly conductive copper using a mandrel-drawn process to control tip tolerance in high-temperature applications.
• Nozzles: These nozzles are made of hard-drawn copper or brass and feature rounded edges to minimise weld spatter build-up.

How does a water-cooled MIG gun work?

Water-cooled MIG guns feature an integrated cooling mechanism that utilises a dedicated circuit for water circulation. This water is drawn from a separate cooler or chiller and directed through the gun's cable assembly. As it passes through the welding cable, nozzle and contact tip, it effectively absorbs and disperses excess heat, ensuring a consistently lower operational temperature.
