V1.0
R AMPS – Set the current between 10 to 200A (peak current when in pulse
mode).
S AC Frequency – Set the AC frequency range between 20 to 250 Hz.
T AC Balance – Set the ratio of positive to negative time during the AC
wave cycle from 1 to 10. The positive part of the AC cycle removes
refractory oxide from the workpiece material's surface, improving the
weld. Higher numbers removes more oxide, but also increases the heat
level of the tungsten.
U Downslope Timer – Set the time duration from 0 to 10 seconds for the
power to fall once the welding has ended. Longer durations will help
eliminate crater and pin holes in the weld.
OPERATION
THERMAL OVERLOAD PROTECTION
Constantly exceeding the duty cycle can damage the cutting unit. An internal
thermal protector will open when the duty cycle is exceeded, shutting OFF all
cutting unit functions except the cooling fan. Leave the cutting unit turned
ON with the fan running. The thermal protector will automatically reset and
the cutting unit will function normally again once it has cooled.
Wait at least another 10 minutes after the thermal protector opens before
resuming cutting. Starting before this additional time may result in a
shortened duty cycle.
OVER-VOLTAGE
This equipment has an automatic voltage compensation function, which
enables the unit to maintain the voltage within the given range. In case that
the input voltage or amperage exceeds the stipulated value, it is possible to
damage the equipment's components. Please ensure your primary power
supply is correct (See Specifications).
POLARITY
Placement of the dinse connector determines the torch's polarity.
Direct Current Electrode Negative (DCEN)
Insert the dinse connector into the negative output socket (C). The torch or
electrode has negative polarity in this configuration. Connect the earth clamp
to the positive output socket (B).
DCEN welding imparts more heat into the workpiece, creating a deeper
molten pool for easier penetration. It is suitable for thicker workpieces.
