Welding is of many types. SMAW or Shielded Metal Arc Welding is a complicated name for arc welding. In arc welding an electrode coated with flux is the one which aids in making welds. Electric arc is produced with the help of AC or DC power. Here the shielding gas is formed when flux starts to disintegrate and vaporize. It resists contamination. Below are the basics of using an arc welder.

• Dc is used to produce smooth welds.
• AC produces more spatters.
• Direct Current Electrode Negative is named as Straight Polarity and Direct Current Electrode Positive is named as Reverse Polarity.
• SMAW can lead to defects such as undercut, slag inclusion and porosity.
• Exposed skin welding leads to cancer and brutal medial issues in the long run.
• Spatters are drops of molten metal. They stick to the metal that you are welding. They usually chip off unless you are using your welder at a very high temperature.
