In 2013, Del Caño was elected as national deputy, obtaining 14% of votes in the elections, positioning the PTS in the third place and sending the traditional Democratic Party of Mendoza to fourth place.
During his political campaign, he questioned the high salaries of politicians and proposed that minimum wage be equivalent to a teacher's, which he later presented as a bill and he himself lowered his own salary by donating the better part of it to striking workers, which, according to himself, was inspired by the members of the Paris Commune of 1871.

Once he took office as deputy, he challenged the fact that his fellow deputy Diego Mestre from the Radical Civic Union was allowed to take office too, arguing he had usurped his seat and had taken it from the FIT through fraud.
Unlike the rest of the coalitions in Congress, Del Caño and the FIT refused to vote Julián Domínguez as president of the Chamber of Deputies.
Such was the case too with the Deputies' vice-president.

As deputy, he presented several bills proposing the nationalization of oil, prohibiting outsourcing, dismantling the State's repressive forces, including government espionage and the criminalization of social protests, demanding the declassification of files ranging from times of the Dictatorship to the current government, and questioning the existence of a political caste with higher salaries, proposing they be reduced to that of a teacher or a qualified worker.
Most of his electoral propositions became bills once he took office as deputy.

During a strike of laid-off workers of Lear Corporation in 2014 at their factory in General Pacheco, within Greater Buenos Aires; Del Caño was attacked with rubber bullets from the National Gendarmerie while he was supporting a picket line in the Pan-American Highway.
Later, as he was attending a session in the chamber of deputies, he was harassed by bureaucrats of the Mechanics and Allied Automotive Transport Trade Union (SMATA from its Spanish acronym), a union that has publicly supported the layoffs of delegates and dissident activists.
After Del Caño's complaint, judge Sandra Arroyo Salgado ordered that the National Gendarmerie could no longer make operations within the highway.
