TIG WELDING FUNCTIONS
ALUMTIG QUICK START GUIDE
200
Function
PULSE TIME ON (10-90% NA EASY MODES)
Purpose
The pulse consists of two stages: Welding amps (upper /Peak) and Pulse amps (lower/background
current). This is represented by a % of total time the pulse spends in the pulse amp stage of the
cycle during one full pulse. The feature can be used to increase or decrease pulse amp time
relative to the welding amp time of the cycle to help manage heat input.
Function
PULSE FREQUENCY (1-500Hz NA EASY MODES)
Purpose
Represented by Hertz (Hz), the pulse frequency denes the actual number of times each second
the pulse makes one complete cycle between welding amps (peak/high amp value) and pulse
amps (background/low amp value).
Function
HF ON/OFF
Purpose
HF - High Frequency Start which allows non contact starting of the arc or when o (lift tig)
requires contact with the metal to initiate the arc (for AC and DC). (HF is selected when symbol is
not striked out) The lift start function on the ALUMTIG 200 provides a cold electrode for safety,
and prevents accidental starts.
Function
AC BALANCE (50-98% NA EASY MODES)
Purpose
Controls arc cleaning action when welding on AC. Adjusting the % electrode negative (EN) AC
wave controls the width of the cleaning zone surrounding the weld. Lower percentage AC
balance more cleaning action but less penetration. Higher percentage AC balance less cleaning
action but more penetration. PRO TIP: Typically a range between 65% - 75% is used. 75% for new
material 65% for oxidised old material.
