-
The CUT55 MP requires a minimum of 60 PSI and at least.
We recommend a compressor rated at 90 PSI or higher
with a tank of at least 20 gallons for sustained cutting.
Oil-free compressors are preferred. If your compressor has an
oil-lubricated pump, install the included air filter to help prevent oil
mist from reaching the torch, as contamination can significantly shorten
consumable life.

240VClean cut: up to 18 mm / 11/16"Maximum severance: up to 26 mm / 1"
110VClean cut: approximately 10 mm / 3/8"Maximum severance: approximately 14 mm / 9/16"
For shop work on steel thicker than 3/8", use 240V for better cut
quality, full output, and reduced risk of overheating.
-
HF, or High Frequency, plasma cutters use a high-voltage spark to start
the arc. This can generate electromagnetic interference that may affect
computers, CNC controllers, vehicle ECUs, solar inverters, and other
nearby electronics.
The CUT55 MP uses a Non-HF blow-back start. Air pressure
retracts the electrode to initiate the arc without producing
radio-frequency interference.
This makes it a safer choice for auto shops, garages, fabrication areas,
and other environments containing sensitive electronics.
-
The CUT55 MP uses IPT60 torch consumables, including
electrodes, nozzles, swirl rings, and shields.
Important:
IPT60 consumables are not compatible with the AG60 consumables used by
the CUT55 Prolux and CUT55 Pro. Do not mix the two systems.
IPT60 consumables are designed to offer improved heat resistance and
durability compared with the IPT40 series.

PAPilot Arc Delay
Controls how long the pilot arc remains active before the main
cutting arc transfers to the workpiece. It is adjustable from
2 to 10 seconds.
Use a longer delay when cutting rusty, painted, coated, or dirty
metal so the pilot arc has more time to penetrate surface
contamination.
PTPost-Flow Time
Controls how long air continues flowing after the trigger is
released. This cools the torch nozzle and electrode.
A setting of 1–3 seconds can help extend consumable life and reduce
tip burn-back.
