A-5 INSTALLATION A-5
Using fuses or circuit breakers smaller than
recommended may result in "nuisance" shut-off
from welder inrush currents even if not welding at
high currents.
1Also called "inverse time" or "thermal/magnetic" circuit
breakers; circuit breakers which have a delay in tripping action
that decreases as the magnitude of the current increases.
INPUT RECONNECT PROCEDURE
On multiple input voltage welders, be sure the
machine is connected per the following instructions
for the voltage being supplied to the welder.
Failure to follow these instructions can cause
immediate failure of components within the welder
and void machine's warranty.
Multiple voltage models are shipped connected for
the highest voltage. To change this connection refer
to the following instructions.
ELECTRIC SHOCK can kill.
Turn the input power OFF at the
disconnect switch or fuse box
before working on this equipment.
. Have a qualified electrician
install and service this
equipment.
. Turn the input power OFF and unplug the
machine from the receptacle
before working on this equipment.
. Allow machine to sit for 5 minutes minimum to
allow the power capacitors to discharge before
working inside this equipment.
. Do not touch electrically hot parts.
. Machine must be plugged into a receptacle
that is grounded according to the National
Electrical Code and local codes.
. Do not remove or defeat the purpose of the
power cord ground pin.
RECONNECT PROCEDURE
The Inverter machine auto reconnects to either
115V or 230V supply.
Fuse the input circuit with time delay fuses or delay
type1 circuit breakers. Using fuses or circuit
breakers smaller than recommended may result in
“
nuisance
”
shut-offs from welder inrush currents
even if not welding at high currents.
The Inverter machine is recommended for use on
an individual branch circuit.
1Also called
“
inverse time
”
or
“
thermal/magnetic
”
circuit breakers.
These circuit breakers have a delay in tripping
action that decreases as the magnitude of the
current increases.
220/230/240V INPUT
The equipment is provided with a 230 cable,
6.6ft.(2m) in length with a 230V attachment plug.
The Inverter machine performs best when
connected to 230VAC inputs. This input allows full
output of the machine (315 amps).
ATTACHMENT PLUG INSTALLATION
Connect the white (neutral) wire under terminal
clamp with silver screw, and black (hot) wire under
terminal clamp with brass screw. Connect green
wire under terminal clamp with green screw.
. Failure to wire as instructed may cause
personal injury or damage to equipment.
To be installed or checked by an
electrician or qualified person only.
In all cases, the green or green/yellow grounding
wire must be connected to the grounding pin of the
plug, usually identified by a green screw.
Attachment plugs must comply with the Standard
for Attachment Plugs and Receptacles,.
The product is considered acceptable for use only
when an attachment plug as specified is properly
attached to the supply cord.
For use on engine drives, keep in mind the above
input draw restrictions and the following precaution.
