500x.
The CAN protocol is used for communication between the
power source and the wire feeder. All signals from the
power source are displayed on the User Interface located
in the wire feeder machine.
Set of power source and wire feeder allow welding in
listed processes:

GMAW (MIG/MAG),

FCAW,

SMAW (MMA),

GTAW,

CAG.
The complete package contains:

Wire feeder.

USB memory with operator’s manual.

Easy Start.
Recommended equipment, which can be bought by
user, was mentioned in the chapter "Accessories".
Installation and Operator Instructions
Read this entire section before installation or operation
of the machine.
Exploitation conditions
This machine can operate in harsh environments.
However, it is important to use the following simple
preventive measures that will ensure its long life and
reliable operation:

Do not place or operate this machine on a surface
with an incline higher 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. 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 away from the item.

This machine has a protection rating of IP23. Keep it
dry when possible and do not place it on a wet
ground or in puddles.

Locate the machine away from a radio controlled
machinery. Normal operation may adversely affect
the operation of a 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

Input Supply Connection
Check the input voltage, phase, and frequency of the
power source that will be connected to this wire feeder.
The acceptable level of input voltage is indicated in the
section „Technical Specifications
ʺ and on the rating plate
of the power source. Verify the connection of grounding
wires from the power source to the input source.
