PARAMETER
pressed then released, from INITIAL CUR to PEAK or BASE current
PEAK CUR.
This parameter sets the PEAK weld current when in PULSE mode
A This parameter sets the TIG WELD current in STD, SLOPE, REPEAT and
SPOT modes when PULSE is off. This parameter also sets the STICK
(WELD)
weld current.
BASE
(Background
This parameter sets the Background current when in Pulse TIG mode.
Current)
This parameter sets the duration of the SPOT TIME in HF TIG mode only
SPOT TIME
PULSE WIDTH
This parameter sets the percentage on time of the PULSE FREQUENCY
for PEAK weld current when the PULSE is on.
PULSE FREQ.
This parameter sets the PULSE FREQUENCY when the PULSE is on.
AC
This parameter operates in AC mode only and is used to set the frequency
FREQUENCY
for the AC weld current.
This parameter is used for aluminium AC TIG mode and is used to set the
penetration to cleaning action for the AC weld current. Generally WAVE
BALANCE is set to 50% for AC STICK welding. The WAVE BALANCE
control changes the ratio of penetration to cleaning action of the AC TIG
welding arc. Maximum weld penetration is achieved when the WAVE
BALANCE control is set to 10%. Maximum cleaning of heavily oxidised
aluminium or magnesium alloys is achieved when the WAVE BALANCE
control is set to 65%.
WAVE BALANCE=50%
WAVE
BALANCE
Balanced with 50% penetration
This parameter works only in AC mode and is used to set the negative
current value of AC welding current.
VR CUR The VR current cannot be set beyond the output current range.
The minimum output current during AC welding is 10 A.
The maximum output current is 300A in AC mode and 200A in
