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.
NOISE APPEARES DURING WELDING CAN BE HARMFUL: Welding arc can cause noise with high
level of 85dB for 8-hour week day. Welders operating welding machines are obligated to wear the
proper ear protectors /appendix No. 2 for the Decree of the Secretary of Labor and Social Policy from
17.06 1998 – Dz.U. No. 79 pos. 513/. According to the Decree the Secretary of Health and Social
Welfare from 09.07.1996 /Dz.U. No. 68 pos. 194/, employers are obligated to carry examinations and
measurements of health harmful factors.
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.
Installation and Operator Instructions
Read this entire section before installation or operation
of the machine.

installation.
•
Do not touch metal portions of the LN-25™ PRO
work clip when the welding power source is on.
•
Do not attach the work clip to the wire feeder.
•
Connect the work clip directly to the work, as close
as possible to the welding arc.
•
Turn power off at the welding power source before
disconnecting the work clip from the work.
•
Only use on power sources with open circuit voltages
less than 110 VDC.
Location
For best wire feeding performance, place the LN- 25™
Pro on a stable and dry surface. Keep the wire feeder in
a vertical position. Do not operate the wire feeder on an
angled surface of more than 15 degrees.
Do not submerge the LN-25™ Pro.
The LN-25™ Pro is rated IP23 and is suitable for
outdoor use.

The handle of the LN-25™ Pro is intended for moving
the wire feeder about the work place only.
When suspending a wire feeder, insulate the hanging
device from the wire feeder enclosure.
High Frequency Protection
WARNING
Locate the LN-25™ PRO away from radio controlled
machinery. The normal operation of the LN-25™ PRO
may adversely affect the operation of RF controlled
equipment, which may result in bodily injury or damage
to the equipment.
Weld cable size
Table 1 located below are copper cable sizes
recommended for different currents and duty cycles.
Lengths stipulated are the distance from the welder to
work and back to the welder again. Cable sizes are
increased for greater lengths primarily for the purpose of
minimizing cable drop.
Electrode lead
The electrode lead is a 4/0 cable.
