What is a satisfactory duty cycle for Shielded Metal Arc Welding (SMAW)?
75%
What is another term for 'workpiece lead cable' in the context of welding?
Ground cable
What effect does the absence of flux covering on the electrode have on the weld?
The weld will have inadequate protection from contaminants and may result in porosity.
How does the absence of flux covering affect the stability of the arc during welding?
The absence of flux covering may cause instability in the arc during welding.
What is the consequence of using an electrode without flux covering in terms of slag formation?
Inadequate flux covering leads to insufficient slag formation and removal, affecting the quality of the weld.
