principle of MMAW

The symbol for SMAW indicates the type of welding

• arc welding

• GAS welding

• MIG welding

The electric current used in welding

• AC - DC

• BC - NC

• FG- HG

The temperature at the start of the welding process reaches

• from 100 to 300

• from 5000 to 7000

• from500 to 700

An arc is struck by contacting the electrode on the work-piece and maintaining gap (about..............).

• 3 to 4 mm

• 10 to 14 mm

• 20 to 30
