3.01 Location
SECTION 3:
INSTALLATION
Adequate air circulation is needed at all times in order to
assure proper operation. Provide a minimum of 12 inches
(305 mm) of free airspace on all sides of the unit. Make
sure that the ventilator openings are not obstructed. Ventilation
air flow is from rear to side.
3.02 Voltage Changeover
For proper operation and to prevent damage to the machine,
the voltage changeover must be set according to
the incoming AC line voltage. Remove the left side panel
of the machine to gain access to the voltage changeover
board. Set the links to agree with one of the four available
voltage settings. (See Figures 3-1 through 3-4).
The four settings are:
200 VAC
230 VAC
400 VAC
460 VAC
1. Check the name plate of the machine for proper
line voltage.
2. Move the voltage links by loosening the nuts securing
the links in place. For 200 and 230 VAC
settings place the two links in the 200/230V positions.
For 400 and 460 VAC settings place the two
links directly on top of each other in the 400/460V
position. See figures 3-1 through 3-4. Make sure
that the connections are properly tightened.
DANGER
ELECTRIC SHOCK CAN KILL.
Open the main wall disconnect switch or breaker,
before removing any covers or access panels on the
welding machine. Live voltage is still present even
with the front panel control switch OFF. Wait at
least three full minutes after power has been removed
before removing any covers or access panels
to allow adequate time for internal capacitors
to discharge.
