TIG AC/DC Welding machines







The applied Panasonic 300 WX3 Mix-Tig power source makes use of a double inverter control, offering the following methods:

AC TIG
• Very stable welding arc both for high and low currents;
• Fast IGBT transistor technology
• AC square-wave without high-frequent currents between welding;
• 3 types AC-wave: AC Standard, AC Soft and AC Hard



MIX TIG
• alternative AC and DC between welding of aluminium;
• better cleaning operation
• deeper burning-in at equal heat-input
• equal burning-in at less energy (metallurgic advantage)
• less stress on the electrode
• unique for Panasonic



DC TIG
• Very stable arc ignition within 0.001 sec., mainly important for robot welding;
• IGBT technology also guarantees less noise during ignition and welding;

PULSE TIG
• Low Pulse Control: 0.5 – 25 Hz for uniform penetration, different material thickness, various materials and simple wire feeding;
• Middle Pulse Control: 10 – 500 Hz for thin plates at higher speeds, purer melting bath at high speeds and easy corner joints;



Extra
• Adjustable cleaning operation arc



Safety
• Warnings for fluctuating supply voltage and too high temperatures, too high input-current and output-voltage and too low cool water level for the welding torch
• Prevention of electrocution with DC electrode welding
• Pulse detection, current detection and emergency stop

Cold wire feeding if applicable
• 4-roll drive for stable feeding of welding wire
• wire alignment set for compensation bending
• continuous and adjustable wire feeding
• intermittent wire feeding with adjustable pauses (synchronised with pulse welding current)
