“Stand back. Things are gonna get hot.”
The Welder thrives on a good emergency. Give him a week to repair a broken deck plate and he’ll yawn and put off the work until tomorrow, but tell him that he has 45 seconds to fix a cracked pipe or the whole sewage system will blow, and he’ll jump into action and get it done just in the nick of time.
With a mask to shield his eyes from sparks and bright light, and heavy-duty overalls to protect the rest of him, the Welder sets to work with his welding torch in hand. As metal sizzles and the clock ticks down, his concentration never falters until the job is done, and done right. This is one Minifigure who can definitely take the heat!
