Installation And Operator Instructions - Lincoln Electric POWER WAVE STT Operator's Manual

WELDED MATERIALS CAN BURN: Welding generates a large amount of heat. Hot surfaces and
materials in work area can cause serious burns. Use gloves and pliers when touching or moving
materials in the work area.
SAFETY MARK: This equipment is suitable for supplying power for welding operations carried out in
an environment with increased hazard of electric shock.
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.
Location and Environment
Mount the STT Module directly to the bottom of a
compatible Power Wave "S" series power source
utilizing the quick lock mechanism as shown.
The STT Module will operate in harsh environments and
can be used outdoors. Even so, it is important that
simple preventative measures are followed in order to
assure long life and reliable operation.

The machine must be located where there is free
circulation of clean air such that movement into and
out of the louvers will not be restricted.

Dirt and dust that can be drawn into the machine
should be kept to a minimum. The use of air filters
on the air intake is not recommended because
normal air flow may be restricted. Failure to observe
these precautions can result in excessive operating
temperatures and nuisance shutdown.

Keep the machine dry. Shelter from rain and snow.
Do not place on wet ground or in puddles.

Do not mount the Power Wave "S" series power
source and STT Module combination over
combustible surfaces.

Control Cable Connections
General guidelines
Genuine Lincoln control cables should be used at all
times (except where noted otherwise). Lincoln cables
are specifically designed for the communication and
power needs of the Power Wave systems. Most are
designed to be connected end to end for ease of
extension. Generally, it is recommended that the total
length not exceed 30,5m. The use of nonstandard
cables, especially in lengths greater than 7,6m, can lead
to communication problems (system shutdowns), poor
motor acceleration (poor arc starting), and low wire
driving force (wire feeding problems). Always use the
shortest length of control cable possible, and DO NOT
coil excess cable.
