Gateshead lost further ground on the Skrill Premier play-offs when they went down to a disappointing defeat at Welling who scored in each half.
The Tynesiders have now won just one of their last seven games and they were behind early on in Kent.
Gateshead were breached after just seven minutes at Park View Road. Joe Healy had scored the Wings’ early goal in a 1-1 draw on Tyneside last month and the midfielder was at it again in the rematch.
Just at the International Stadium Healy was found by Ross Lafayette and he gave Welling the initiative with a fine strike from outside the box through a ruck of players.
The Wings were on the front foot with Toby Ajala’s pace causing problems and Adam Bartlett was forced to save from Harry Beautyman.
James Brown fired over from a central position, Jamie Chandler shot just wide and defender James Curtis had a header cleared off the line.
The Heed keeper had to save from Ajala in the first minute of the second half and manager Gary Mills threw on line-leader Liam Hatch 11 minutes in.
Welling, however, doubled their lead before the hour when Alfie Mawson headed home Beautyman’s corner. It was Mawson’s first goal for the club, Gateshead responding by giving 38-year-old former Nottingham Forest striker Jack Lester his debut. Lester fashioned an opening for Marcus Maddison but Butcher was equal to the effort, livewire Maddison putting another effort wide. Hatch put a header wide late on while Healy put a free kick over the bar.
