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 www.tecproducts.co.uk.

Cutting capacity is usually described in terms of clean cut and maximum cut thickness, and the two are worth distinguishing. Clean cut is the thickness a machine handles with a good edge finish and reasonable speed, while maximum cut is the thickest material the machine will get through at all, usually slower and with a rougher edge. Buying with your typical material thickness in mind, rather than the thickest job you might occasionally face, generally gives a better day-to-day result.

Getting the right disc for the material and finish you're after saves both abrasives and time, and it's worth checking your current selection against the job list with a supplier who stocks a full abrasives range, such as www.tecproducts.co.uk.

Helmet choice comes down to the mix of processes you run and how much you're prepared to spend for extra sensors or a wider shade range, and it's a straightforward conversation to have with a stockist that carries several options, including www.tecproducts.co.uk.

Most people buying their first welder get stuck at the same fork in the road: MIG, TIG or MMA. Each process strikes an arc differently and suits a different type of work, so the right choice depends more on what you'll be building than on which machine looks the most impressive on a shelf.

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.
