Keeping A Stock Of The Right Tungsten Types, Collets And Gas Lens Sizes For The Work You Do Avoids A Lot Of Avoidable Downtime, And It's The Sort Of Consumables Range Worth Sourcing From A Specialist Supplier Like Tec Products UK.
The figure changes with output. Turn the amperage down and the duty cycle climbs, because the internal components are working less hard. This is why a welder can feel completely different in a busy production environment compared with occasional home workshop use: someone welding continuously through a shift needs a much higher duty cycle at their working amperage than someone doing short repair jobs a few times a week. It's the kind of spec worth comparing properly across brands such as Kemppi and EWM, not just reading off the headline amperage figure.
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 Tec Products UK.
Before choosing a machine, it's worth checking what your workshop's consumer unit and incoming supply can actually handle, not just what socket is nearest the bench. Buying a three-phase-only machine for a single-phase workshop, or underestimating the load a higher-output single-phase welder places on existing wiring, are both avoidable problems with a bit of checking upfront.

The abrasive material itself matters as much as the shape. Discs formulated for steel typically contain aluminium oxide, while stainless steel usually calls for an inox-rated disc that's free from iron, sulphur and chlorine contaminants that could otherwise cause surface corrosion on the stainless. Aluminium and other soft, non-ferrous metals need their own dedicated abrasives too, since standard steel discs tend to clog quickly and produce a poor finish on softer materials.
Duty cycle is one of the most misunderstood figures on a welder's spec sheet, yet it tells you more about real-world usability than the headline amperage does. It's expressed as a percentage over a ten-minute period at a given output, so a machine rated at 30% duty cycle at its maximum amperage can run for three minutes out of every ten at that setting before it needs to rest and cool.
