I thought pre-heat was a waste, but a boiler repair changed my mind

I always had issues with cracks... a clean weld on a boiler jacket last week fixed that.

Ever think pre-heat was pointless? Fixed my boiler cracks too.

Not just for boilers, @robertanderson uses pre-heat for welds.

Pre-heat made my welds stick better too.
