Answers to common questions about torch switches, cable covers, adaptors, quick connectors and accessory kits for this style of TIG torch.
How do I know which accessory kit or part fits my TIG torch?
Start with the torch type and the model marking on the torch body, handle or data plate, then check the torch manual or parts list for the part you need. Accessory kits are usually sold against a list of torch families and a contents chart, so read the chart to see exactly which collets, cups and spares are included and what size they are.
Makers warn that fitting consumable parts from other makers, or fitting them in the wrong order, can damage the torch. If the part number is not clear, our team can help you match it to your torch.
Is a gas lens kit worth choosing over a standard collet body kit?
A standard collet body releases shielding gas through a few small holes, which can become turbulent. A gas lens uses a diffuser and fine mesh to spread the gas more evenly in a smoother column, which gives better coverage and usually allows the tungsten to stick out further for better visibility in tight joints.
At short stick-out the difference can be small, and a gas lens needs a matching insulator and cup. If you mostly weld open, easy joints a standard set-up may be enough; if you weld corners, fillets or reactive metals, a gas lens is worth considering. Follow the torch maker's parts list for compatible items.
Should I choose a torch switch or a foot control?
A torch switch is an on/off control, so the current is whatever you set on the machine. It suits tack welds, repetitive short welds and awkward positions where dragging a foot pedal around is a nuisance. A foot control (or a thumb or finger control on the torch) lets you vary current while you weld, which gives finer control of the weld pool and the end of the weld.
Check that the switch or remote you choose is compatible with your welding machine's control socket and wiring, and choose a cable long enough to reach comfortably without being pulled tight. The machine manual will say what is supported.
What does a leather cable cover do and when is it worth fitting?
A cable cover is a sleeve that wraps around the torch lead bundle (power cable, gas hose and, on water-cooled torches, the water hoses). It protects them from abrasion when dragged over rough surfaces and from sparks, slag and hot spatter from nearby work. Leather is commonly chosen where heat and spatter are a concern; woven nylon covers are lighter.
Measure the bundle first, because the inside diameter must suit the leads, and a hook-and-loop fastening makes it easy to fit and to remove for inspection. A cover is no substitute for checking the leads regularly: take it off now and then and look at what is underneath.
What should I check on the torch lead, switch cable and connectors before welding?
HSE guidance says arc welders using hand-held equipment are at risk of electric shock and electrical burns, and that the insulation on welding cables, plugs, clamps and the torch should be undamaged. Connectors should be clean, undamaged and correctly rated for the current required.
Before each job, look along the lead, switch cable and gas and water hoses for cuts, crushing, kinks, scorching or loose fittings, and check the torch handle and any switch housing for cracks. Do not use damaged equipment: take it out of use and have it repaired or replaced as the maker's instructions and your risk assessment require.
What are pre-flow and post-flow, and do my accessories affect them?
Pre-flow starts the shielding gas before the arc is struck, so the metal and tungsten are not exposed to air at the start. Post-flow keeps gas flowing after the arc stops, protecting the cooling weld and the hot tungsten. Welding guidance generally advises longer post-flow on stainless steel and titanium, which oxidise more readily.
Both are set on the welding machine, not on the torch, but accessories matter: a leaking connector, adaptor or hose can let air in and undo the protection. Longer tungsten stick-out also leaves more of the electrode exposed, so it generally calls for good coverage. Check your machine manual for the adjustable range and the material supplier's advice.
