If You're Not Sure Which Supply A Particular Machine Needs Or Whether Your Workshop Can Support It, It's A Sensible Question To Put To A Supplier Before Ordering, And The Team At Tec Products Ltd Can Talk Through The Options Against Your Existing Set-up.
Every workshop is different, so rather than relying on general advice, it's worth getting your own set-up properly assessed. A system that works well for one shop can be quite wrong for another with different ventilation, floor space or process mix, and an on-torch extraction option, such as those available for Fronius torches, suits a different layout to a fixed overhead hood.
If you're still working out which process fits your workload, it helps to talk it through with people who field these questions every day rather than guess from a spec sheet, and the team behind Tec Products Ltd in Thirsk deal with exactly this kind of query on the advice line.
Plasma cutting uses a jet of ionised gas, usually compressed air, forced through a nozzle at high speed and heated by an electric arc to a temperature hot enough to melt through electrically conductive metal. The molten material is then blown clear by the same jet, leaving a narrow, clean cut. Unlike oxy-fuel cutting, plasma works on any conductive metal, including stainless steel and aluminium, not just carbon steel. Hypertherm is the plasma cutting brand we get asked about most, and it's worth understanding the basics before comparing specific units.
TIG welding relies on a handful of small consumable parts inside the torch that have an outsized effect on how the arc behaves. The tungsten electrode itself doesn't melt into the weld; it simply carries the arc, and different tungsten types, distinguished by their alloying elements, suit different current types and materials. Getting the wrong tungsten for the job typically shows up as arc wander or poor arc starts long before it shows up anywhere else.
A reliable, adequately sized compressed air supply is the part most first-time buyers underestimate. Undersized or contaminated air, whether from moisture, oil or an undersized compressor, is one of the most common causes of poor cut quality and shortened consumable life, so it's worth checking a machine's air requirements against what your compressor can actually deliver before you buy, not after.
If you're not sure which supply a particular machine needs or whether your workshop can support it, it's a sensible question to put to a supplier before ordering, and the team at Tec Products Ltd can talk through the options against your existing set-up.
