<p>JewellC1120274: </p> <hr /> <div>The collet and collet body hold the tungsten in place and need to match its diameter exactly. A worn or incorrectly sized collet allows the tungsten to shift slightly during welding, which affects arc stability in ways that are easy to blame on technique when the actual cause is a consumable that needs replacing. CK Worldwide and Furick are two of the ranges we stock here, and these are inexpensive parts, but neglected ones cause a disproportionate amount of frustration at the torch.&lt;br&gt;&lt;br&gt;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.&lt;br&gt;&lt;br&gt;Portability and durability matter depending on how the table gets used. A shop building large frames or vehicle chassis needs a solid, well-supported table that won't flex under load, while a mobile fabricator or someone working across multiple sites benefits more from a lighter, foldable design. Material and construction quality affect long-term flatness too, since a table that warps under heat from repeated welding stops being reliable exactly where it matters most.&lt;br&gt;&lt;br&gt;Abrasive discs look interchangeable on a shelf but perform very differently depending on what they're made from and what they're used on. Cutting discs are generally thin, designed to slice through material quickly with minimal heat build-up, while grinding discs are thicker and shaped to remove material from a surface or clean up a weld, rather than cut all the way through it.&lt;br&gt;&lt;br&gt;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 [http://tarchouni.de/index.php?title=Benutzer:DQHSalvador www.tecproducts.co.uk] can actually deliver before you buy, not after.&lt;br&gt;&lt;br&gt;Surface flatness and tolerance are the starting point, but fixturing is what turns a flat plate into a genuinely useful tool. Tables with a grid of holes or T-slots let you bolt down clamps, stops and jigs in repeatable positions, which speeds up repetitive fabrication and makes it far easier to hold parts square while tacking. A table without any fixturing options usually ends up needing extra clamps, magnets or improvised supports to achieve the same result.</div>
