DELTA 140E/160E 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 compact welding machine able to weld with all types of electrodes (not high-yield electrodes) at
currents up to 140/160 amps.
The combination of low weight and compact design makes the DELTA 140E/160E 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 140E/160E is very easily operated since it is only fitted with one knob for infinitely variable
adjustment of the welding current from 10-140A on DELTA 140E and 20-160A on DELTA 160E.
Information on single phase welding machines without PFC
(Applicable in the European Union Directive-regulated areas)
According to IEC 60974-10 which e.g. includes single-phase welding machines without PFC
(Power Factor Correction), the user should note the following before connecting equipment to
public networks in countries within the EU:
Power plants set out more stringent requirements for "harmonic leakage current" as of
01.12.2010, cf. IEC 61000-3-12; For all products without PFC, regardless of make, there is a
risk that the current in the sine curve is not as harmonic as required by power plants. The CE
marked product, Delta 140E/160E, does not meet the requirements for short circuit impedance
on the mains supply. This means that the user before connecting the equipment must make
sure that the local network is suitable for single-phase products without PFC. If in doubt, it is
recommended to seek the advice of the electricity supplier or other qualified advisers.
There are no special requirements for products connected to closed networks, such as
generators or similar equipment.
The Delta 140E/160E without PFC meets all other CE marking requirements.
