Power Equipment
What this page is
buythis.co.za/power-equipment is the Power Equipment hub on Buythis, AM.CO.ZA's online shop. It groups the workshop utilities that keep machines such as lasers, CNC routers, plasma cutters and printers running safely: clean, stable electricity of the right phase, and dry, clean compressed air or nitrogen. The hub also links to the main machine ranges (laser machines, plasma cutters, CNC routers, digital printers, 3D printers and vinyl cutters). Cooling, dust extraction and vacuum pumps have their own pages, listed under related pages below.
Why it matters
- Unstable mains damages electronics. South African supply can sag, surge or drop out during load shedding and when big loads start. Laser power supplies, printhead boards, servo drives and spindle inverters fail early on poor voltage. A voltage stabiliser keeps the output close to 220 V or 380 V.
- Many industrial machines need three-phase 380 V. Larger CNC routers, fibre lasers, plasma cutters, screw compressors and liquid-ring vacuum pumps run on three-phase power. Where only single-phase 220 V is available, a phase converter can make three-phase power on site.
- Laser cutting, plasma cutting and CNC tools need compressed air. Air assist keeps lenses clean and blows away smoke and dross; it must be dry and oil-free, or it damages optics and torches.
- Nitrogen gives clean cut edges. Fibre laser cutting of stainless steel and aluminium, laser welding shield gas and some CO2 laser jobs use nitrogen instead of air, and a PSA generator makes it from compressed air.
Phase converter
PhaseMagic converts single-phase 220 V into three-phase 380 V for CNC machines and workshop equipment, so you can run a three-phase machine where the municipality only supplies single phase.

Voltage stabilisers (AVR)
Fully automatic servo stabilisers, also called variac voltage regulators or AVRs, correct a wide input range back to a steady output. The 3 kVA model suits single-phase 220 V machines such as desktop lasers, printers and vinyl cutters. The 50, 100 and 150 kVA models are three-phase 380 V units for large CNC, fibre laser and plasma installations. A stabiliser is not a UPS: it corrects voltage but does not keep the machine running when the power goes off.

Tips for choosing and using power equipment
- Check the machine's rated power and voltage on its product page, then size the stabiliser or converter with spare capacity for motor and spindle start-up current.
- Put the stabiliser between the supply board and the machine, and wire three-phase units exactly as shown in the wiring video below.
- During load shedding, switch machines off before the power goes and let stabilisers settle before switching back on. Printers need extra care; see the load-shedding printhead video.
- Drain water from the compressor tank and air dryer regularly, and change screw-compressor oil and filters on schedule, then reset the maintenance counter.
- Use an air treatment unit before any laser, plasma torch or nitrogen generator so moisture and oil never reach the optics.
