WELDING MACHINES
WIG Inverters AC/DC
Two of the most modern technologies in the field of welding, digital and analogue, are in-built TIG Inverters for direct or alternating current
welding. This allows welding of all kinds of metals, including aluminum. We can decide between two versions according to welding parameters
adjustment mode – classic, analogue operating system (AC/DC) with power switches for individual settings or digital operating system (HDp)
with three microprocessor switches for all operating parameters. All the settings are monitored on a digital display and can be saved on 18
program memory posts.
The following welding parameters can be adjusted:
• Electric arc ignition
• Two or four cycle welding mode
• Reduced initial welding current in % according to the main welding current
• Welding current increase period
• Amount of welding current
• Decrease of terminating welding current in % according to the main welding current
• Welding current decrease period
• Cooling gas post flow time
• Welding current oscillation
The digital version also allows welding current pulsation adjustments within the frequency range of 1 and 150 Hz as well as pulsating power
percentage adjustment according to the selected welding current. This enables higher thermal protection of the welding material and as a
result reduced possibility of material texture changes.
Alternating welding current (AC) is suitable for welding aluminum and aluminum alloys. Due to a higher melting temperature of alumina, which
covers the surface, we need to break the oxide with current oscillations and only then we can melt the core with pure welding current. Thanks
to this special welding method the amount of material overheating is reduced to minimum. At the same time WIG Inverters allow welding with
all types of coated electrodes up to 6mm in diameter.
