Effect of welding parameters on the weld bead 
Welding issues due to weak welding current are
Arc voltage beyond optimum value generates
Increased welding speed can cause
Reduced welding voltage generates
Slow welding speed
Faster welding speed generates
Unreasonably high welding voltage can result in
Low welding current can cause
for welding thicker material electrode diameter should be
