The Flex-Loc™ series torch is a variable-angle torch that locks into any position within a 360-degree rotation. Interchangeable heads allow different size tungsten and head sizes to be quickly and efficiently changed. The patented Flex-Loc™ TIG Torch is available in water-cooled and gas-cooled models. Great for applications requiring a unique angle yet allowing the user a rigid torch. Ergonomically designed to help eliminate fatigue. Applications: Cup walking on pipe root welds, welds that require a mirror to access weldment, and welds requiring different tungsten sizes.
Answers to common questions about complete water-cooled TIG torch packages with flexible cables and machine connections.
TWI notes that lower currents use smaller electrodes and air cooling, while higher currents need a larger torch and water cooling. A water-cooled torch suits heavier material, higher currents and long, continuous welding, where an air-cooled torch can get too hot.The trade-off is extra equipment and upkeep: you need a cooler unit and coolant, and a little more maintenance. Compare your highest welding current and your typical weld time with the torch rating on the data plate or in the manual before you decide.
You need a TIG machine with a compatible torch connection, a coolant circulating unit, shielding gas and coolant. A water-cooled setup has more connections than an air-cooled one: the power lead, a gas connection and two water hoses, one carrying coolant to the torch and one returning it.The power cable is cooled by the returning coolant, so it must never be run dry. Check how your machine and cooler connect and whether the cooler can be powered from the machine, and read the manuals for both before first use.
Use the coolant that the cooler and torch makers specify. Torch makers advise against car antifreeze, which can coagulate and clog lines, and against ordinary tap water, which can corrode the system. Do not dilute a pre-mixed coolant, as that weakens its protection.Many TIG coolers call for a low-conductivity coolant, partly because of the high-frequency arc start. Check the cooler manual for the right product and the change interval, which depends on the maker and how heavily you use it.
Yes. Water or coolant on the floor near welding equipment is a shock hazard, so fix leaks promptly and wipe up spills before welding. Keep connectors, the machine and the cooler dry, and replace any hose that is cracked, bulging or leaking.If you find a leak at a torch connection, switch the machine off and isolate it before dealing with it. Where a torch repeatedly leaks or overheats, it should be replaced or repaired by a competent person following the maker's instructions and your risk assessment.
