ARC-160 is a professional Stick Arc with Lift-TIG welding machine using the advanced inverter technology. The welding power source can provide a stronger, more concentrated and more stable arc. When the stick and work-piece become shorter, the response will be faster. This means it is easier to design it as a welding machine with different dynamic characteristics, and it can even be adjusted as needed to make the arc softer or harder.
