EVERYDAY WELDING COMFORT
Kemppi presents the latest in their TIG torch range; the Flexlite TX series. These TIG torches are designed for the best reliable welding performances with a focus on the process of everyday welding. All Flexlite TX products feature tremendous technical performance lifespans and there is plenty of different sizes and types to choose from to fit your welding needs. Flexlite TX welding torches provide excellent user comfort and lowers the chance of welder fatigue. A firm grip is made from silicone rubber and the torches’ innovative design reduces time in wrist loading, allowing more time to concentrate on welding tasks.
All Flexlite TX welding torches comply with standard IEC 60974-7.
Answers to common questions about choosing, connecting and looking after 4-pin TIG torches, including scratch start versions with a gas valve.
Only if the machine has a matching control socket. The control connector carries the start signal from the handle switch, so it has to match the socket on your power source. Torches are made with different control plugs, commonly 4-pin or 7-pin among others, and the plug must match the socket on your machine. A similar-looking plug is not proof of compatibility, and adapters are not a substitute for checking the wiring.Look up the torch or remote socket in your welding machine's manual and compare the connector type and pin function before you order. If the machine has no suitable socket, check whether it is a stick power source, in which case a valve torch may be the right type.
A scratch start torch has a manual gas valve in the torch body and a simple connector instead of a control plug. You use it with a stick (MMA) welding machine. Open the valve to start the shielding gas, then strike the arc by scratching or touching the tungsten on the work. It is designed for equipment that cannot control gas for you.Scratch start can contaminate the tungsten and weld, so it is not recommended for critical welds. If your machine has a TIG torch socket and gas control, a standard torch without a valve is normally the better match. Check which ignition methods your machine supports.
Air-cooled torches use the shielding gas and surrounding air for cooling, so they are lighter and need no extra equipment. Water-cooled torches connect to a cooling unit and generally carry higher current for longer, with a lighter, more flexible cable.A water-cooled torch typically has a control plug, a welding cable that also carries the coolant return, a coolant supply hose and a separate gas hose, though the layout varies between makers, so you need to plug in every one. Choose from the current and duty cycle you need, using the figures on the torch data plate rather than a general rule.
A water-cooled torch typically has a control plug, a welding cable that also carries the coolant return, a coolant supply hose and a separate gas hose, though the layout varies between makers. The gas is supplied separately from the coolant circuit.Make sure each coolant hose goes to its correct connector, because if the connections are crossed the torch and torch body may overheat. Tighten the connectors as the manual says. Loose connectors can overheat, cause poor contact and lead to water or gas leaks. Always read the connection steps in your torch and cooling unit instructions.
Not on every torch. Many torches have a simple ON/OFF start switch on the handle, and how that switch behaves (for example 2T or 4T operation) depends on your welding machine's settings. Current adjustment from the handle is only possible on torches with a remote-type control in the handle, and basic 4-pin versions often do not have it.If you want to change current while welding, check the specification of the torch you are considering, or plan to use a separate foot or hand remote control on a machine that supports one. Our team can help you choose.
Pick the shortest cable that gives you comfortable reach. A shorter lead is easier to manage in tight spaces and is less likely to catch, while a longer lead gives more freedom around large work. Remember that remote controls and earth leads need to reach too, so extending only the torch cable may not solve the problem.Whatever the length, avoid sharp bends and kinks in the cable and check the protective hose for damage, because cable damage is a common cause of heating and gas leaks. The lengths made and any limits for your torch are listed in the specification.
