This was supposed to be a banana skin tie for Glenavon but, on the day, it was no more than a stroll for Gary Hamilton’s men.
Sadly the sixth round draw was not kind and paired the men from Mourneview against either champions Linfield or Crusaders.
And victory came at a cost because Hamilton, Eddie McCallion and Mark Haughey picked up injuries.
All three are doubtful starters along with new signing Mark Farren, Niall Henderson and Brendan Bennett for tomorrow night’s crucial league clash with Dungannon Swifts at Stangmore Park.
Goals from Marc Brown, Guy Bates, Ciaran Martyn and subs Andy McGrory and Robbie McDaid made it oh so easy and made a mockery of the pre-match hype suggesting the Lurgan outfit was vulnerable.
There was never a chance of an upset with Welders merely nicking a controversial consolation as the game eased into time added on.
Bates was the main man helping to tee up four of the five goals and Welders boss Paul Miskelly was brutally honest.
He said: “It could have been more. Our plan was to make sure they didn’t settle and to put the foot in to rattle them.
“We came hoping but we couldn’t get near them. They have quality and they made it pay. They were a lot sharper to the ball and moved it quickly to penetrate us.
“I reckon our defensive display was the worst for three years but you cannot take anything away from Glenavon and I hope they can go on and win it.
“We would have had to play really well to have got something from the game but we didn’t even run them close. Glenavon were really determined.”
Home boss Hamilton said: “We were very professional. There can be upsets in the Cup and we didn’t want to be the fall guys.
“We dominated for all but a sloppy 10 minutes in the second half. All I wanted was to be in the draw for the next round and we made it.”
On the draw he said: “There were easier ones but you have to take the hand you are dealt. Some of our best performances have been against the better teams so we’ll take things as they come.”
