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.
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 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. 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.
Minutes or decrease
duty cycle
Input Supply Connection
Installation and mains outlet socket shall be made and
protected according to appropriate rules.
Check the input voltage, phase, and frequency supplied
to this machine before turning it on. Verify the
connection of grounding wires from the machine to the
input source. The allowable input voltages is 3x400V
50/60Hz. For more information about input supply refer
to the technical specification section of this manual and
to the rating plate of the machine.
Make sure that the amount of mains power available
from the input supply (connection) is adequate for
normal operation of the machine. The necessary fuse
(or circuit breaker) and cable sizes are indicated in the
technical specification section of this manual.
Refer to points [1] and [12] of the images below.
Output Connections
Refer to points [4], [5] and [6] of the images below.
Controls and Operational Features
1. Power Switch ON/OFF (O/I): It controls the
machine power input. Be sure the power source is
connected to the mains supply before turning power
on ("I").
2. Status Light: A two color light that indicates system
errors. Normal operation is steady green light. Error
conditions are indicated, per TABLE 1.
NOTE: The status light will flash green, and
sometimes red and green, for up to one minute
when the machine is first turned on. This is a
normal situation as the machine goes through a self
test at power up.
