SECTION  2 

 INSTALLATION

2.5  PRIMARY ELECTRICAL INPUT  

 

       CONNECTIONS 

ELECTRIC SHOCK CAN KILL! PRECAUTIONARY MEASURES 

SHOULD BE TAKEN TO PROVIDE MAXIMUM PROTECTION 

AGAINST ELECTRICAL SHOCK. BE SURE THAT ALL POWER 

IS OFF BY OPENING THE LINE (WALL) DISCONNECT SWITCH 

AND BY UNPLUGGING THE POWER CORD TO THE UNIT 

WHEN CONNECTIONS ARE MADE INSIDE OF THE POWER 

SOURCE.

Be sure that the power source is properly configured for 

your input power supply. DO NOT connect a power source 

configured for 115V to a 208/230V input power supply. 

Damage to the machine may occur.

The  HandyPlasma

®

 250  power source operates on 115 VAC, 

1-phase input power and is equipped with a 8 ft. (2.4m), 3-

conductor cable.  The customer is responsible for supplying 

a plug with a NEMA 6-30 rating minimum ir desired.

THE CHASSIS MUST BE CONNECTED TO AN APPROVED 

ELECTRICAL GROUND. FAILURE TO DO SO MAY RESULT 

IN ELECTRICAL SHOCK, SEVERE BURNS OR DEATH.

2.1   GENERAL  

Proper installation will insure satisfactory and trouble-free 

operation of the HandyPlasma

®

 250 cutting package.  It is 

suggested that each step in this section be studied carefully 

and followed.

2.2  EQUIPMENT REQUIRED

A source of clean, pre-filtered dry air that supplies 250 cfh at 

75 psig (118 l/m @ 5.2 bar) is required for the cutting opera-

tion. The air supply should not exceed 150 psig (10.3 bar) 

(the maximum inlet pressure rating of the air filter-regulator 

supplied with the package). 

2.3    LOCATION

Adequate ventilation is necessary to provide proper cooling 

of the HandyPlasma

®

 250 and the amount of dirt, dust, and 

excessive heat to which the equipment is exposed, should 

be minimized.  There should be at least one foot of clearance 

between the HandyPlasma

®

 250 power source and wall or 

any other obstruction to allow freedom of air movement 

through the power source.

Installing or placing any type of filtering device will restrict 

the volume of intake air, thereby subjecting the power source 

internal components to overheating.  The warranty is void if 

any type of filter device is used.

2.4  INSPECTION

A. 

Remove the shipping container and all packing mate-

rial  and  inspect  for  evidence  of  concealed  damage 

which may not have been apparent upon receipt of the 

HandyPlasma

®

 250.  Notify the carrier of any defects or 

damage at once.

B. 

Check container for any loose parts prior to disposing 

of shipping materials.

C. 

Check air louvers and any other openings to ensure 

that any obstruction is removed.

A line (wall) disconnect switch, with proper sized fuse or 

circuit breaker (see Table 2.1), should be provided at the 

main power panel. 

*

  Sized per National Code for 80°C  rated copper conductors @ 30°C ambient. Not more than three conductors in 

raceway or cable. Local codes should be followed if they specify sizes other than those listed above.
