A gas lens sits in place of the standard collet body and uses a fine mesh to straighten the shielding gas flow into a smoother, more laminar stream around the arc. This generally allows a longer stick-out from the cup without turbulence pulling in surrounding air, which is particularly useful when working in tighter joints or awkward positions where the torch needs to sit further back from the work. 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. Budget for a first machine is rarely just the welder itself. A gas cylinder and regulator for MIG or TIG, a decent auto-darkening helmet, gloves and basic workshop ventilation all add to the real cost of getting started, and skimping on the supporting equipment tends to cost more in frustration than it saves in cash. It's worth pricing the whole set-up before settling on a machine at the top of the budget. Space and power supply are the other two practical constraints worth checking early. Confirming that a chosen machine will run comfortably from the electrical supply actually available in the workshop, and that there's room to work safely around it with materials laid out, avoids the common mistake of buying a machine that then can't be used the way it was intended. If you're weighing up options for your own workshop, from portable units to fixed installations, it's worth talking through the layout with a supplier who stocks a range of systems, such as [http://cmc365.co.kr/bbs/board.php?bo_table=free&wr_id=763109 welding tables]. Our own TP Weld Tables range is designed and manufactured in-house in Yorkshire, cut on a fibre laser for tight tolerances, which is the kind of detail worth asking about wherever you're sourcing a table, and you can see the full range via welding tables.
