Installation and Operator Instructions

Read this entire section before installation or operation
of the machine.

Product Description

The PW345 is a semiautomatic multi-process DC arc
welding machine offering CV and CC DC welding. It is
rated for 350Amps at 35% and 300 amps at 60% duty
cycle. Equipped with the correct wire feeder (LF40 code
54000 and above), this machine is able to weld CC-
Stick, CC-GTAW, CV-FCAW, synergic and non-synergic
CV-GMAW / synergic GMAW-P processes. The digital
microcomputer based control system allows easy and
accurate adjustment of weld parameters through the
multi-process panel located on the wire feeder.
It is available with :
- 230 VAC/ 3.5 amp auxiliary power for water cooler.
For a quick and easy handling within the welding area, it
is factory mounted on a built-in undercarriage equipped
with a platform for a gas cylinder.
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 7° from horizontal.
This machine must be located where there is free
circulation of clean air without restrictions for air
movement to and from the air vents. Do not cover
the machine with paper, cloth or rags when switched
on.
Dirt and dust that can be drawn into the machine
should be kept to a minimum.
This machine has a protection rating of IP23. It can
be used in moderate raining conditions without
causing any danger for users' safety..
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.
This machine cannot be used for pipe thawing.
Input Supply Connection
Check the input voltage, phase, and frequency supplied
to this machine before turning it on. The allowable input
voltage is indicated in the technical specification section
of this manual and on the rating plate of the machine.
Verify the connection of grounding wires from the
machine to the input source.
The frame of this machine must be grounded. A ground
terminal located on the base of the generator is provided
for this purpose.
This machine is factory 3ph-400V connected. To connect
it in 3ph-230V, remove the left case panel of the
machine (A) to have access to the input reconnect
panel. Modify the connections according to the
connection diagram located on the inside of the case
side.
Gas Connection
Once a gas cylinder has been securely installed on the
machine, connect the gas hose of the input cable to the
gas cylinder using a flow regulator.
Output connections
Ground cable delivered with the machine has Twist-mate
plugs for connection to the POWER WAVE 345.
Use the shortest possible cable lengths.
When using an pulse type power source like
thePowerWaves, use the largest welding (electrode and
work) cables that are practical, even if the average
output current would not normally require it. When
pulsing, the pulse current can reach very high levels.
Voltage drops can become excessive, leading to poor
welding characteristics, if undersized welding cables are
used.
Changing Polarity
Connect the output lead to the desired polarity and the
ground lead to the other terminal.
The positive terminal marked (+) is the standard
configuration. This polarity is mainly used on GMAW and
FCAW-GS welding mode.
The negative terminal marked (-) is mainly used on
FCAW-SS ( Innershield) welding mode.
Negative electrode polarity :
When operating with electrode polarity negative the
"Electrode Sense Polarity" DIP switch must be set to the
"Negative" position on the Wire Drive Feed Head PC
Board. The default setting of the switch is positive
electrode polarity. Consult the Wire Drive instruction
manual for further details.
