The six-axis AR1730 robot provides fast and accurate performance for a range of arc welding applications. While a slim profile allows for high-density robot placement, a contoured arm gives easy access to parts in close spaces, avoiding potential fixture interference. An extensive robot reach accommodates a wide variety of parts. The AR1730 has a patented double-yoke upper arm, and it utilizes a symmetric wrist with a substantial range, providing equal torch access to both sides of a part. A 50 mm thru-hole reduces cable wear and interference.
