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, welds requiring different tungsten sizes.

Answers to common questions about complete air-cooled TIG torch packages with a flexible one-piece cable and a machine connection.
For lower welding currents an air-cooled torch is the usual choice. TWI notes that lower currents use smaller electrodes and air cooling, while higher currents need a larger torch and water cooling. Air-cooled torches can also get too hot during long, continuous welding runs.Look at the highest current you will actually weld at and how long you weld without a break, then compare that with the torch rating on its data plate and in the manual. If you regularly run near the limit, step up to a higher-rated or water-cooled torch rather than pushing the air-cooled one.
Aluminium and magnesium form tough oxides, so TWI says an AC power source is typically needed to weld them. Makers' data sheets for air-cooled torches usually list a lower current for AC than for DC at the same duty cycle, so the figure that matters for aluminium is often the lower one.Check the AC rating, not just the headline DC figure, when you plan to weld aluminium. If you need to run close to the AC limit for thicker material or longer welds, a higher-rated or water-cooled torch is usually the safer choice. The data plate and manual give the exact figures for your torch.
A longer cable gives more reach from the machine, which helps on large fabrications or when the machine has to stay put. A shorter cable is easier to manage, less likely to tangle or get trodden on, and has fewer places to kink.Choose the shortest length that comfortably reaches your work without pulling on the connections. Extra cable can be coiled loosely, never in tight loops, and should be kept away from sharp edges and heat. Always keep within the current rating given by the maker for that cable, which is on the data plate or in the manual.
Check three things on your machine. First, the power connection: connector types and sizes differ between machines. Second, whether the shielding gas is routed through that connection or comes from a separate outlet. Third, the thread type and size on the torch end, which should match the machine fitting or a suitable adaptor.If the sizes differ, use a correct adaptor rather than forcing a fit, and make sure the adaptor is rated for the current you will use. Check the manuals for both the torch and the machine, and contact us if you are unsure which fitting you have.
