INVERTER MULTI-PROCESS WELDER KIT

POWER SUPPLY

Before installing the machine, consider

the availability and proximity of the

required power supply circuit. If an

existing circuit does not meet the

requirements for this machine, a new

circuit must be installed. To minimize the

risk of electrocution, ﬁre, or equipment

damage, installation work and electrical wiring must be done by an electrician or

qualiﬁed service personnel in accordance with all applicable codes and standards.

FULL-LOAD CURRENT RATING

The full-load current rating is the amperage a machine draws at 100% of the rated

output power. On machines with multiple motors, this is the amperage drawn by the

largest motor or sum of all motors and electrical devices that might operate at one

time during normal operations.

Full-Load Current Rating at 230V ..... 17.5 Amps

Full-Load Current Rating at 120V...... 17.5 Amps

The full-load current is not the maximum amount of amps that the machine will

draw. If the machine is overloaded, it will draw additional amps beyond the full-

load rating. If the machine is overloaded for a sucient length of time, damage,

overheating, or ﬁre may result— especially if connected to an undersized circuit. To

reduce the risk of these hazards, avoid over- loading the machine during operation

and make sure it is connected to a power supply circuit that meets the speciﬁed

circuit requirements.

CIRCUIT INFORMATION

A power supply circuit includes all electrical equipment between the breaker box

or fuse panel in the building and the machine. The power supply circuit used for

this machine must be sized to safely handle the full-load current drawn from the

machine for an extended period of time. (If this machine is connected to a circuit

protected by fuses, use a time delay fuse marked D.)

CAUTION!

For your own safety and protection of property, consult an electrician if you are

unsure about wiring practices or electrical codes in your area.

Note: Circuit requirements in this manual apply to a dedicated circuit—where only

one machine will be running on the circuit at a time. If machine will be connected to

a shared circuit where multiple machines may be running at the same time, consult

an electrician or qualiﬁed service personnel to ensure circuit is properly sized for

safe operation.

CIRCUIT REQUIREMENTS FOR 230V

This machine is prewired to operate on a power supply circuit that has a veriﬁed

ground and meets the following requirements:
