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. Interpretation is shown below:
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.
Input Supply Connection
Warning! 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
MAGPOWER 2100 i must be connected to
a correctly installed plug-in socket with an earth pin.
Input voltage is 1x230V, 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 "D" characteristic) and cable sizes are indicated in the
technical specification section of this manual.
Warning! The welding machine can be supplied from an engine driven generator of output power at least
30% larger than input power of the welding machine. Engine driven generator must have voltage
stabilizator. Otherwise, may cause a damage. See "Technical Specifications" chapter.
Warning! 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!
