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.
Excessive extension of the duty cycle will cause the
thermal protection circuit to activate.
The machine is protected from overheating by a
thermostat. When the machine is overheated the output
of the machine will turn "OFF", and the Thermal Indicator
Light (on front panel of wire feeder) will turn "ON". When
the machine has cooled to a safe temperature the
Thermal Indicator light will go out and the machine may
resume normal operation. Note: For safety reasons the
machine will not come out of thermal shutdown if the
trigger on the welding gun has not been released.

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 of the power 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.
Gas Connection
A gas cylinder must be installed with a proper flow
regulator. Once a gas cylinder with a flow regulator has
been securely installed, connect the gas hose from the
regulator to the machine gas inlet connector. Refer to
point [8] of the images below. The wire feeder supports
all suitable shielding gases including carbon dioxide,
argon and helium at a maximum pressure of 5,0 bar.
Output Connections
Refer to point [1] of the images below.
Controls and Operational Features
1. EURO Socket: For connecting welding torch.
2. WFS (Wire Feed Speed) Control Knob:
It enables continuous control of wire
feeding speed in the range from 1.0 to
20m/min with manual mode or correction of the speed
automatically matched by the machine in the range
50% at synergic mode.
Before welding beginning and during Cold Inch Switch
using the Wire Feed Slow Run Control Knob [12] has also
an influence on the wire feeding speed.
3. Thermal Overload Indicator: This lamp
will light up when the machine is
overheated and the output has been
turned off. Leave the machine on to allow the internal
components to cool, when the lamp turns off normal
operation is possible.
