Cooling welds with water can cause weld cracks and affect the mechanical properties of the __ - Base
metal✅✅✅
Cooling with water is only done on _ - Practice coupons✅✅✅
Engine generators should be shut down if no welding is to take place for more than__ minutes -
10✅✅✅
For an open-root V-groove weld, root reinforcement should be flush to _ - 1/8"✅✅✅
For better puddle control when welding vertically, you should _ - Set the amperage in the lower part
of the suggested range✅✅✅
Groove weld should be made with slight reinforcement and a gradual transition to the base metal at

Groove welds should be made with slight reinforcement and a gradual transition to the base meta at
each - Toe✅✅✅
Hand tools for preparing a welding surface and cleaning completed well include __ - Files, wire
brushes, and chipping hammers✅✅✅
Horizontal welds can be made on a horizontal open-root V-groove or on a(n) _ - Vertically positioned
flat surface✅✅✅
If 3/8" carbon steel is not available, practice welds can be made on steel __ to 3/4" thick -
1/4"✅✅✅
If the tip of an SMAW electrode is touched and held against the workpiece instead of allowing for a
gap between the two, the electron will __ - Pass the electricity directly to the work piece without
creating an arc✅✅✅
In a transformer-rectifier type welding system, AC voltage is reduced to a lower voltage level, and
