Yup... just lotsa-lotsa inert gas and a low enough amperage so that you
can have the weldment cool enough before leaving the gas shield.
Oh... it doesn't make a weldor happy to see the bottom-side of the work
catch fire, so gas should be applied to both sides of the work.

Purge box, even a taped up cardboard box enclosing the deck with just
enough access to get to the weld area. Pre-purge with plenty of argon
before welding, set post flow to the max time available.
