Welch was a full-blood Chippewa born in Spooner, Wisconsin. He attended the Carlisle Indian School, located in Carlisle, Pennsylvania and graduated in 1911. Gus was one of Carlisle's first honor students. While at Carlisle, Welch was the quarterback for the schools football team, that featured Jim Thorpe and was coached by Glenn "Pop" Warner. He was a member of the USA Track and Field team during the 1912 Summer Olympics, although an illness prevented him from competing. After 1912, Welch played professional football for the Canton Bulldogs, coached by Thorpe. In 1917, Welch graduated from the Dickinson School of Law.
In 1917, he entered the American Expeditionary Force during World War I as a Second Lieutenant, 808th Pioneer Infantry, under John J. Pershing. During his time in the military he achieved the rank of captain. He left the service in 1919.
Welch was the 15th head college football coach for the Washington State University Cougars located in Pullman, Washington and he held that position for four seasons, from 1919 until 1922.  His coaching record at Washington State was 16 wins, 10 losses, and 1 tie. As of the conclusion of the 2007 season, this ranks him tenth at Washington State in total wins and 13th at Washington State in winning percentage (0.611). 
From 1923 to 1929, he was the athletic director and head football coach at Randolph Macon College. From 1930 to 1934, he served as the head lacrosse coach at Virginia. From 1937 to 1938, he served as head football coach at American University where he compiled an overall record of two wins, ten losses and one tie. From 1938 until 1940, Welch served as the Director of Athletics and Head Football Coach at Haskell Indian Nations University, located in Lawrence, Kansas. Afterwards he served as the Head Coach at Georgetown Prep School.
During World War II was in charge of Physical Fitness at Georgetown University; and by 1947 taught physical education at Lyndon Hill Junior High School, located in Prince George County, Virginia.
In 1929, Welch purchased a boy's camp near the Peaks of the Otter in Bedford County, Virginia, which he operated during the next 30 summers as Camp Kewanzee for young people. In 1939, some of his land was condemned by the US Department of the Interior to extend the Blue Ridge National Park, a seizure Welch fought vigorously. He then purchased a farm near Bedford, Virginia, and continued to work with young athletes. Gus finally served as Athletic Director at American University in Washington, D.C. prior to his 1970 death.
In 1973, Welch was named to the American Indian Athletic Hall of Fame and in 1975 to National Football Foundation's College Football Hall of Fame. In the late 1960s, Welch's help was sought by both the Jim Thorpe Project of Carlisle, Pennsylvania, and the Jim Thorpe Athletic Award Committee of Yale, Oklahoma.
In 1923, Welch married Julia Carter, daughter of Charles David Carter, Oklahoma Congressman from Boggy Depot. A Chickasaw, Carter descended from David Carter, a white man captured in Connecticut and raised as an Indian who elected to remain with them as an adult, married an Indian woman, and for a time edited The Phoenix, an Indian newspaper. The Welchs had no children but adopted a niece, Serena, who became the model for the figure portrayed on the canning labels of Pocahontas Foods.
Carter's family was also close to Vinnie Ream, after whom Vinita, Oklahoma is named. Ream became a sculptor of several statues in Washington, D.C., including one of Abraham Lincoln placed in the United States Capitol rotunda.
