How To Learn Arc Welding. You also need to understand how to control the arc and this requires knowledge of the welding circuit and the equipment that provides the electric current used in the arc. If you are asking yourself how to arc weld and maintaining travel speed you simply need to keep the arc in the leading 13 of the weld pool.
How long does it take to learn welding. As the electrode is brought near the base metal 2-4 mm apart where the welding is to be done spark or arc starts to produce in between the base metal and electrode. For most arc welding the rod is moved in a straight line to form a stringer.
Adjust your welders output amperage to suit the material you are welding and the desired penetration of the arc.
In the video the arc is started with a tap start. It is important for welders to understand the symbols as much as learning how to properly weld. If you find the finished weld bead is pitted with deep cratering at the beads edges or the adjacent metal is simply melted or burned away reduce the amperage incrementally until the condition is corrected. This tutorial is intended to offer practical advice to beginner arc welders.
