Tandy recognises the challenge of travelling to play the Pumas represents a higher level for his squad, with Wales ranked 11th in the world and Argentina currently seventh.
“It’s a great opportunity to see how far our development has come and to play a world-class team in their own backyard,” said Tandy.
“We know this is a major challenge for us. There’ll be lots of passion, they’re at home, it will be be hostile.
“It’s just an exciting opportunity for us to embrace that. The boys are used to playing in hostile environments but it will probably be a bit more intense this weekend.
“It will be a great experience but ultimately it is making sure we stay connected as a team on that field because we’ll have to survive some moments.
“When we get an opportunity to put ourselves in the game, it’s about making sure we are ruthless.”
Tandy’s side have had limited preparation time given the party was split over two flights on consecutive days from London Heathrow to Buenos Aires for a journey that spanned 7,000 miles, took 18 hours and crossed four time zones.
This resulted in just one full training day with the whole squad on Wednesday and the following day there was another two-hour flight to San Juan from Argentina’s capital.
“It’s a good test and there are no excuses,” said Tandy. “It’s character building and good for us to bond as a team.
“I love these tours and it can bring out the best in you.”
