Installation and Operator Instructions

Read this entire section before installation or operation of
the machine.
Location and Environment
This machine will operate in standard 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 10° 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 IP21S. 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.
English
Break for 4 minutes.
For GMAW and FCAW-SS process, the technical
specification describes:

Type of welding wire

Wire diameter.
Recommended equipment, which can be bought by user,
was mentioned in the chapter "Accessories".

Input Supply Connection
Only a qualified electrician can connect the welding
machine to the supply network. Installation had to be
made in accordance with the appropriate National
Electrical Code and local regulations.
Check the input voltage, phase and frequency supplied to
this machine before turning it on. Verify the connection of
ground wires from the machine to the input source. The
welding machine BesterMig 200-S, must be connected to
a correctly installed plug-in socket with an earth pin.
Input voltage is 230V, 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 is adequate for normal operation of the
machine. The necessary delayed fuse (or circuit breaker
with "B" characteristic) and cable sizes are indicated in the
technical specification section of this manual.
The welding machine can be supplied from a power
generator of output power at least 30% larger than input
power of the welding machine.
When powering welder from a generator be sure to turn
off welder first, before generator is shut down, in order to
prevent damage to welder!
Output Connections
Refer to points [10], [11 and [12] of the Figure 2.
