System description
The Powermax45 is a highly portable, 45-amp, handheld and mechanized plasma cutting
system appropriate for a wide range of applications. The Powermax45 uses air or nitrogen to cut
electrically conductive metals, such as mild or stainless steel or aluminum. With it, you can cut
thicknesses up to 1 inch (25.4 mm) and pierce thicknesses up to 3/8 inch (9.5 mm).
The standard Powermax45 system includes a complete set of the consumables needed for cutting
(shield, retaining cap, swirl ring, nozzle, electrode), 2 spare electrodes, 2 spare nozzles, gouging
consumables (handheld configurations only), a quick-disconnect air fitting (1/4 NPT on CSA
units and 1/4 NPT x G-1/4 BSPP on CE units), a consumables box, a shoulder strap, an Operator
Manual, a Quick Setup Card, and a Setup DVD. Mechanized configurations include a remote-start
pendant as well.
You can order additional consumables and accessories – such as the plasma cutting guide – from
any Hypertherm distributor. See Section 6, Parts, for a list of spare and optional parts.
The power cords on the CSA power supplies are shipped with a 50 A, 250 V plug (NEMA 6-50P)
on the power cord. The CE units are shipped without a plug on the power cord. See Prepare the
electrical power in Section 2 for more information.
