SWEISS SKYWORKS 3550 has another feature: Synergic control of the welding current and voltage.
SKYWORKS SERIES arc welding machine is suitable for all positions welding for various plates made of
stainless steel, carbon steel, alloyed steel, copper, titanium, etc, which is also applied to pipe installment,
mould mend, petrochemical, architecture decoration, car repair, bicycle, handicraft and common
manufacture.
MAG--Metal Active Gas Welding
MIG--Metal Insert Gas Welding
2.2 Working Principle
The working principle of SKYWORKS SERIES arc welding machine is shown as the following gure.
three-phase 220/440 V work frequency AC is recti ed into DC （530V） , then is converted to medium
frequency AC (about 40KHz) by inverter device (IGBT), after reducing voltage by medium transformer
(the main transformer) and rectifying by medium frequency recti er (fast recovery diodes), and is
outputted by inductance ltering. The circuit adopts current feedback control technology to insure
current output stably when MMA or TIG. And adopts voltage feedback control technology to insure
voltage output stably when MIG. Meanwhile, the welding current parameter can be adjusted
continuously and in nitely to meet with the requirements of welding craft.

2.3 Volt-Ampere Characteristic
SKYWORKS SERIES welding machine has an excellent
volt-ampere characteristic, whose graph is shown as the
following gure. The relation between the rated loading
voltage U2 and welding current I2 is as follows:
