AC TIG WELDING QUICK START UP
ELECTRIC SHOCK can kill.
.
Have an electrician install
and service this equipment.
. Turn the input power off at
the fuse box, disconnect or
unplug supply lines and allow machine
to sit for five minutes minimum to allow
the power capacitors to discharge before
working inside this equipment.
. Do not touch electrically hot parts.
Connect the shielding gas
–
typically argon
–
using a appropriate regulator. Connect the
Adjustable foot control
, torch and work lead to
the power source.
With the work cable connected to a properly
grounded work piece, turn the power source on.
The Inverter machine is ready to AC TIG weld with
the following features:
. AC TIG
. Local control
. AC Square Wave
. AC Balance(sp%) 50% EN
. AC Frequency 100Hz
. Post Flow 5 sec.
. High Freq Start
Set the maximum output current desired using the
Output Control. Initiate the arc by closing the arc
start switch. The
Adjustable foot control
will
control the output current from 10 amps to current
level set by Output Control.
To change the AC Frequency,
Regulating
the AC Frequency knob, It can be selected
between 20 to 250Hz..
The AC Frequency is now
selected and can be varied by the Output Control.
To change the (SP%) AC Balance,
Regulating the
AC SP% knob, It can be selected between
10% TO 90%
.
Adjust the Output Control for the
desired AC Balance.
.
To change the Post Flow time
, Regulating the
Post flow knob, It can be selected between 1 to
10s. Adjust the Output control to the desired Post
Flow time.
DC TIG WELDING QUICK START UP
ELECTRIC SHOCK can kill.
. Have an electrician install
and service this equipment.
. Turn the input power off at
the fuse box, disconnect or
unplug supply lines and allow machine
to sit for five minutes minimum to allow
the power capacitors to discharge before
working inside this equipment.
. Do not touch electrically hot parts.
Connect up the shielding gas
–
typically argon
–
using an appropriate regulator. Connect
Adjustable
foot control
, torch and work lead to power source.
With the Work cable connected to a properly
grounded work piece, turn the power source on.
To change to DC TIG Welding:
. Press Mode button to select "DC TIG."
. Press Local / Remote Mode button and set for
Remote.
Set the maximum output current desired using the
Output Control.
Initiate the arc by closing the
Adjustable foot
control
s arc start switch. The
Adjustable foot
control
will control the output current from 10 amps
to current level set by output control.
To change the Post Flow time, repeatedly push the
Parameter button until the Post Flow indicator light
is on. Adjust the Output control to the desired Post
Flow time as indicated on digital display.
REMOTE CONTROL OPERATION
A
Adjustable foot control(
optional) is included
with the PRECISION TIG models and available for
other models (See Accessories Section) for remote
current control while TIG welding. An Arc Start
Switch may be used to start and stop the welding if
no remote control of the current is desired. Refer to
the Accessories Section of this manual.
Both the Hand and
Adjustable foot control
work in
a similar manner. For simplicity, the following
explanation will refer only to "Ampcontrol", meaning
both Foot and Hand models. The term "minimum"
refers to a foot pedal in the "up" position, as it would
be with no foot pressure, or a Hand Ampcontrol in
the relaxed position, with no thumb pressure.
