2-3. Install procedure
2-3.1. Cutting machine should be installed in a stable position and with good
ventilation. Avoid direct sun outdoors. Avoid transport in invert or side position.
2-3.2. Connect SG55 plasma gun to torch connector (“-“). Attach earth clamp
supplied with the machine into earth connector (“+”). Attached control cable to
the control receptacle. see Figure 2.1.
2-3.3. Connect machine with115/ 208/230V single phase power supplies.
CAUTION
WAIT 30 SEC BEFORE SWITCH TO DIFFERENT
VALTAGE!!
CAUTION
SHOCK HAZARD: ALWAYS TURN OFF THE POWER,
UNPLUG THE CORD AND WAIT 5 MINUTES BEFORE REMOVE AND POWER
SUPPLY COVER. IF THE POWER SUPPLY IS DIRECTLY CONNECTED TO A
LINE DISCONNECTION, PLACE SWITCH IN THE OFF POSITION. IN THE US,
USE A
“
LOCK-OUT/TAG-OUT” PROCEDURE UNTIL THE SERVICE OR
MAINTENANCE WORK IS COMPLETE. IN THE OTHER COUNTRIES, FOLLOW
APPROPRIATE LOCAL OR NATIONAL SAFETY PROCEDURE.
2-3.4. Be sure machine is well grounded.
2-3.5. Gas supply can be either air or Nitrogen. A high pressure regulator must be
used on either type of gas and must be capable of delivering 155 l/min at a
pressure of 5 bar(72psi) to the filter.
2-3.6. Use a 3/8 inch (9.5mm) ID inert gas hose to connect the gas supply (air or
nitrogen) to the power supply filter. To connect the hose, install a 1/4 NPT
nipple to the filer as show in Figure 2.1. Apply liquid pipe sealant to the threads
to ensure a leak-free installation.
Never use Teflon tape when installing the
nipple or adapters. Bits of tape can break off and enter the air line and
harm the pressure regulator, pressure switch and valve.
2-3.7. Use a three-stage coalescing filtration system as shown in Fig 2.2 when site
conditions introduce moisture, oil or other contaminants into the air line.
