General Description - Migatronic DELTA 180 E Manuel D'instruction

GENERAL DESCRIPTION

DELTA 180E is a monophased welding machine based on the Power Mosfets technology. It has
been constructed especially for those applications where welding jobs must be completed quickly
and easily. Using the latest inverter technology, MIGATRONIC has designed and produced a com-
pact welding machine able to weld with all types of electrodes (not high-yield electrodes) at currents
up to 180 amps.
The combination of low weight and compact design makes the DELTA 180E extremely suitable for
installation work, field construction, emergency repairs, etc.
The electronics of the machine will keep the welding current stable at the set level by automatically
readjusting mains voltage and load variations.
DELTA 180E is very easily operated since it is only fitted with one knob for infinitely variable adjust-
ment of the welding current from 20-180 A.
The block diagram illustrates
the principle of the machine.
The machine is equipped with the following fixed functions:
Hotstart:
This auxiliary function helps to establish the arc when MMA welding starts. This is done by
increasing the welding current (when the electrode touches the workpiece) compared to the set
welding current. This function facilitates the ignition of the electrode and results in quicker and
better welding.
Arc control:
When arc and weld pool have been established, this function will ensure that the arc is kept stable,
and that the result will be a more uniform welding.
