WELDER INSTALLATION

POWER SOURCE CONNECTION

Power Requirements

This welder (FP-100) is designed to operate on a properly grounded 120 volt, 60 HZ, single-phase alternating
current (AC) power source fused with a 20 amp time-delayed fuse or circuit breaker. (FP-235 and FP-235
AC/DC requires 230 Volt, 60 Hz, single phase AC with a 50 amp delayed fuse or circuit breaker. Please consult
local codes for proper plug and receptacle applications.) A qualified electrician should verify the 

ACTUAL

VOLTAGE

at the receptacle into which the welder will be plugged and confirm that the receptacle is properly

grounded. The use of the proper circuit size can eliminate the nuisance of circuit breaker tripping when welding.

DO NOT OPERATE THE FP-100 WELDER

if the ACTUAL power source voltage is less than 110 Volts

AC or greater than 132 Volts AC. Contact a qualified electrician if this problem exists. Improper performance
and/or damage to the welder will result if operated on inadequate or excessive power.

DO NOT OPERATE THE FP-235 OR FP-235 AC/DC WELDER

if the ACTUAL power source voltage is

less than 220 Volts AC or greater than 240 Volts AC. Contact a qualified electrician if this problem exists.
Improper performance and/or damage to the welder will result if operated on inadequate or excessive power.

Connection to Power Source

High voltage danger from power source!

Consult a qualified electrician for

proper installation of receptacle at the power source.

This welder must be grounded while in use to protect the operator from electrical shock. If you are not sure if your
outlet is properly grounded, have it checked by a qualified electrician. 

DO NOT

cut off the grounding prong or alter

the plug in any way. 

DO NOT

use any adapters between the welder’s power cord and the power source receptacle.

Make sure the POWER switch is OFF.  Connect the welder's (FP-100) power cord

to a properly grounded 120 VAC, 60 Hz, single-phase outlet. Connect the FP-235 / FP-235
AC/DC to a properly grounded 230 VAC, single-phase outlet.  Contact a qualified electrician if
a problem exists.  Improper performance and/or damage to the welder results if operated on
inadequate or excessive power.

Extension Cords (Applies to FP-100 ONLY)

For optimum welder performance, an extension cord should not be used unless absolutely necessary. If neces-
sary, care must be taken in selecting an extension cord appropriate for use with your specific welder.

Select a properly grounded extension cord that will mate directly with the ac power source receptacle and the
welder power cord without the use of adapters. Make certain that the extension cord is properly wired and in
good electrical condition (minimum gauge size 10/3 AWG).

WELDER ASSEMBLY

The following steps describe the assembly, installation, maintenance and operations of your new welder.

Be sure that the welder’s electrical power supply cord is not connected

while performing this procedure.

Avoid contacts with wires or parts. 

DO NOT

work with the panels partially opened

or removed completely from the power source.

1. Tools required: Hammer, Flat Head Screwdriver, Allen Wrench (metric)
