INSTALLATION
MIGACUT 5i is ready for use after connection to
electric power and compressed air or some technical
gases for plasma cutting.
MIGACUT 5iC (with built-in compressor) is ready for
use after connection to electric power.
Power supply
3~50 Hz 400 V
Fuse: 10A
Gas supply (MIGACUT 5i only)
Air plasma cutting:
Connect the compressed air to the filter regulator and
adjust to 3 bar pressure.
Gas plasma cutting:
Connect the constant flow regulator of the gas
cylinder to the filter regulator and adjust to 3 bar
pressure.
The gas flow should be approx. 15 l/min.
ATTENTION!
The SPARCUT plasmacutting torch for MIGACUT 5i
is supplied with a red hose. The plasma-generating
gas/air flow quantity is determined by a gas injector
(nozzle) in the gas hose connection of the torch
body.
The gas injector is designed for MIGACUT 5i
exclusively, and in order easily to establish this, the
protection cover of the hose is coloured red.

OPERATION
Check that the machine has been properly
connected to the power supply and gas, see the,
Installation.
NOTE!
Use only the machine with a 400V power supply!
Connect the earth-lead to the front of the machine.
Connect the earth clamp directly to the work piece.
If necessary, clean the surface from paint, rust, dirt,
etc.
Cutting sequence
The main switch (Power) is set at pos ON.
The power lamp READY lights, and the pump, fan
(and built-in compressor) start.
Choose process power (cutting current 20-40 A).
Place the torch in position for contact cutting or
distance cutting and activate the cutting start button
on the torch handle.
Contact cutting
The nozzle is placed directly onto the work piece.
Special contact cutting nozzles are available as
accessories for this type of cutting. Contact cutting is
suitable for plate thicknesses up to 4 mm.
Distance cutting
Keep a few millimetres distance between nozzle and
work piece - with or without aids such as distance
guide, support trolley and circle cutting device.
When the cutting start control has been activated,
air/gas will flow for a short while before the plasma
arc (pilot arc) is established. If the cutting process
does not start, the pilot arc will switch off and another
attempt to start can be made a few seconds later.
Stop the cutting process by releasing the START
button on the torch handle. The plasma arc will
switch off instantaneously. Gas/air will flow for a few
more seconds.
PLEASE NOTE!
When the machine is not in use or when the cutting
sequence is seperated by long intervals, the main
switch (power) should be at pos. 0/OFF
The plasmacutter contains working parts such as fan,
pump, (and built-in compressor), which should be
protected against unnecessary wear
Air plasma cutting
Choose a type of electrode intended for use with air
as plasma generating gas.
Characteristics:
This electrode is nickle plated.
