WELDER INSTALLATION
POWER SOURCE CONNECTION
Power Requirements
This welder 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 160 requires 230 Volt, 60 HZ,
single phase AC. 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-120 OR FP-130 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 per-
formance and/or damage to the welder will result if operated on inadequate or excessive power.
DO NOT OPERATE THE FP-160 WELDER if the ACTUAL power source voltage is less than 208 Volts
AC or greater than 245 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. DONOT cut off the grounding prong or alter
the plug in any way. DONOT 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 power cord to a prop-
erly grounded 120 VAC, 60 Hz, single-phase, 20 amp power source. DO NOT operate this
welder if the 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.
Extension Cords
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).
MACHINE ASSEMBLY
1. Unpack the welder.
2. Lay the power source on one side and fix the four rubber feet (front and back) to the base of the machine
using the four screws supplied in the kit. Bring the power source back to the upright position.
