Please be noted:
1. While using argon gas for stopping a strong short circuit arc which leads to the formation of stomata, arc voltage should not be too low, and the arc length should be between 4-5 mm.
2. With argon gas, it performs well (less spattering, good weld molding). To avoid white points you should use the high pure gas and pay much attention to the skill.
