CYLINDER MAY EXPLODE IF DAMAGED: Use only compressed gas cylinders containing the
correct shielding gas for the process used and properly operating regulators designed for the gas and
pressure used. Always keep cylinders in an upright position securely chained to a fixed support. Do
not move or transport gas cylinders with the protection cap removed. Do not allow the electrode,
electrode holder, work clamp or any other electrically live part to touch a gas cylinder. Gas cylinders
must be located away from areas where they may be subjected to physical damage or the welding
process including sparks and heat sources.
MOVING PARTS ARE DANGEROUS: There are moving mechanical parts in this machine, which can
cause serious injury. Keep your hands, body and clothing away from those parts during machine
starting, operating and servicing.
The manufacturer reserves the right to make changes and/or improvements in design without upgrade at the same time
the operator’s manual.
Introduction
PF44
and
PF46
are digital wire feeders which have been
designed to work with all Lincoln Electric power sources
using ArcLink
®
protocol to communication.
Digital wire feeders allow the welding:
•
GMAW (MIG/MAG)
•
FCAW-GS / FCAW-SS
•
SMAW (MMA)
•
GTAW (arc ignition using lift TIG)
Recommended equipment, which can be bought by
user, was mentioned in the chapter "Accessories".
Installation and Operator Instructions
Read this entire section before installation or operation
of the machine.
Location and Environment
This machine will operate in harsh environments.
However, it is important that simple preventative
measures are followed to assure long life and reliable
operation.
•
Do not place or operate this machine on a surface
with an incline greater than 15° from horizontal.
•
Do not use this machine for pipe thawing.
•
This machine must be located where there is free
circulation of clean air without restrictions for air
movement.
•
Dirt and dust that can be drawn into the machine
should be kept to a minimum.
•
This machine has a protection rating of IP23. Keep
it dry when possible and do not place it on wet
ground or in puddles.
•
Locate the machine away from radio controlled
machinery. Normal operation may adversely affect
the operation of nearby radio controlled machinery,
which may result in injury or equipment damage.
Read the section on electromagnetic compatibility in
this manual.
•
Do not operate in areas with an ambient
temperature greater than 40°C.
Duty cycle and Overheating
The duty cycle of a welding machine is the percentage
of time in a 10 minute cycle at which the welder can
operate the machine at rated welding current.
Example: 60% duty cycle
Welding for 6 minutes.
Break for 4 minutes.
Excessive extension of the duty cycle will cause the
thermal protection circuit to activate.

Input Supply Connection
Check the input voltage, phase, and frequency of the
power source that will be connected to this wire feeder.
The allowable input voltage source is indicated on the
rating plate of the wire feeder. Verify the connection of
grounding wires from the power source to the input
source.
