TIG GTAW

The TIG mode features continuous control from 5 to

425 amps. The TIG mode can be run in either the

Touch Start TIG or Scratch start mode.

The Arc Control level selects the starting mode.

Between –10 and 0, the Touch Start TIG mode is

selected. The OCV is controlled below 10V and the

short circuit "TIG touch" current is maintained at

approximately 25 amps, independent of the preset

current. When the tungsten is lifted, an arc is initiated

and the output is regulated at the preset value. A set-

ting of 0, results in the most positive arc initiation. A

setting of -10 reduces the start procedure to start the

weld, and from there, to ramp to the welding proce-

dure over a specified amount of time.

A setting above 0 selects a Scratch Start. Full OCV is

available when the arc initiates the output is regulated

to the preset value

Typically starting procedure on a higher “+” setting is

known as a “Hot Start”. Setting a starting procedure

on a lower setting is known as a “Cold Start”.

Recommended Welding Procedures for Power Mode

NOTE: Later versions of weld software

eliminated the Arc Control Function

in TIG mode and only allow for

“Touch Start” operation.

SMAW

In SMAW (STICK mode), the arc control adjusts the

arc force. It can be set to the lower range (0 to -10) for

a soft and less penetrating arc characteristic or to the

higher range (0 to +10) for a crisp and more penetrat-

ing arc. Normally, when welding with cellulosic types of

electrodes (E6010, E7010, E6011), a higher energy

arc is required to maintain arc stability. This is usually

indicated when the electrode sticks to the work-piece

or when the arc pops-out during manipulative tech-

nique. For low hydrogen types of electrodes (E7018,

E8018, E9018, etc.) a softer arc is usually desirable

and the lower end of the Arc Control suits these types

of electrodes. In either case the arc control is available

to increase or decrease the energy level delivered to

the arc.
