Arc Length
To strike the arc, the electrode should be gently scraped on the work until the arc is established. There is a simple rule for
the proper arc length; it should be the shortest arc that gives a good surface to the weld. An arc too long reduces
penetration, produces spatter and gives a rough surface finish to the weld. An excessively short arc will cause sticking of
the electrode and result in poor quality welds. General rule of thumb for down hand welding is to have an arc length no
greater than the diameter of the core wire.
Electrode Angle
The angle that the electrode makes with the work is important to ensure a smooth, even transfer of metal. When welding in
down hand, fillet, horizontal or overhead the angle of the electrode is generally between 5and 15 degrees towards the
direction of travel. When vertical up welding the angle of the electrode should be between 80 and 90 degrees to the work
piece.
Travel Speed
The electrode should be moved along in the direction of the joint being welded at a speed that will give the size of run
required. At the same time, the electrode is fed downwards to keep the correct arc length at all times. Excessive travel
speeds lead to poor fusion, lack of penetration etc., while too slow a rate of travel will frequently lead to arc instability, slag
inclusions and poor mechanical properties.
Material and Joint Preparation
The material to be welded should be clean and free of any moisture, paint, oil, grease, mill scale, rust or any other material
that will hinder the arc and contaminate the weld material. Joint preparation will depend on the method used include sawing,
punching, shearing, machining, flame cutting and others. In all cases edges should be clean and free of any contaminates.
The type of joint will be determined by the chosen application.
TIG CONNECTION
To use TIG with the Elite COMPACT 160 connect the torch to the negative socket or connector of the machine and the work
clamp (ground) to the positive socket or connector of the machine, as shown in the following picture:
