Backing weld throat thickness should be thin, and the roots of fusion, the closing arc to a gentle slope-shaped arc shrinkage, if received, the application of grinder wear off.

When you solid solder weld thickness should be as thin as the root, and the good, when you want to become an arc-shaped, such as slope, there is a hole, use a grinder grind away.

Hits when the backing weld welded joint thickness should be as far as possible thin, is good with the root fusion, when receiving arc must become the gentle slope shape, if has the receiving arc shrink hole, abrasions using the polishing engine.

End of welding seam thickness should be as thin as possible, with good roots fusion, your ARC to be mild, if your ARC shrinkage, polishing machine grinding away.

Weld thickness of each electrode diameter of 0.8 to 1.2 times the levels of point and arc extinction point should be staggered.
