TIPTIG Hot Wire Unit, Technical Manual

Page: 18 / 63

With the TIP TIG Process, you will be welding with more wire so your weld
current will be higher than normal. 150 – 350 amps is typical. You will have
much longer arc on times. How the tungsten is sharpened will have dramatic
effect on the weld duty cycle attained.
For manual TIP TIG welds you want an included
angle of
“ 25 degree” with a flat on the tungsten
tip. This provides a wider arc plasma suited for
most TIG welds.
For better penetration at high travel rates, you
will need a included angle of
“ 35 degree” . This
angle provides a narrow, more concentrated arc
plasma better suited for automation.
