INVA series products are semi-automatic gas shielded metal ARC welding machine with IGBT inverter technology.

• Easy to operate.
• Suitable for all position welding of mild steel, stainless steel, carbon steel, aluminum & its alloys etc. for both solid wire and flux-cored welding wire with the diameter of 0.8/ 1.0/ 1.2/ 1.6.
• Arc voltage and current feedback control circuit to make the welding process steady, strong adaptability for changes in the Arc length.
• Excellent FTT – Globule control circuit make positive striking of arc.
• Designed with high open circuit voltage and slow wire feeding speed for smooth and steady arc striking/initiation.
• The machine has the characteristics of stable welding process low spatter and good weld. The molten pool is easy to be controlled.
