7 WELDING
7.2
SMAW welding
SMAW welding may also be referred to as welding with coated electrodes. Striking the arc melts the
electrode, and its coating forms protective slag. When the SMAW application is selected, there is a 5 s
delay to protect from unintentional arc strike.
Setting range
The table below shows the setting range for the SMAW application.

Current
A higher current produces a wider weld pool, with better penetration into the workpiece.
Arc force
The arc force is important in determining how the current changes in response to a change in the arc
length. A lower value gives a calmer arc with less spatter.
Hot start
Hot start increases the weld current for an adjustable time at the start of welding, thus reducing the
risk of poor fusion at the beginning of the joint.
7.3
Gouging
For arc air gouging, a special electrode is used comprised of a carbon rod with a copper casing. An
arc is formed between the carbon rod and the workpiece, which melts the material. Air is supplied so
that the melted material is blown away.
When the Gouging application is selected, there is a 5 s delay to protect from unintentional arc strike.
