GENERAL DESCRIPTION & SAFEGUARDS
These are a newly developed TIG AC/DC range of AC/DC and Pulse Welding
Machines. DC function allows the welding of stainless steel, alloy steel and carbon steel
and other nonferrous metals. AC function allows the welding aluminum and aluminum
alloys. The machine is equipped with Pulse function, selection of the pulse function
provides adjustable pulsation of the welding current. Therefore providing better control
of the welding and control of the heat input to the work piece during some applications.
The power exchange rates of this welding equipment are over 85,
and it is energy-saving.
The development of Inverter technology of welding machines has many benefits.
The invention of high power switching components enables these TIG welding
machines to function with HF of 100KHz, thus reducing the volume and weight of the
main components (transformer and inductor). The application of PWM (Pulse Width
Modulation) technology enables the concentration and stability of the welding current
and much more precision of the current adjustment. The unique structuring design
enables ease in the disassembly and maintenance of this welding equipment and
maximizes the EMI.
Exclusive HF Inverter technology, TIG ACDC P series provides many advantages in
comparison to the traditional welding equipment. Smaller in size, lighter in weight,
higher power efficiency rate and more energy saving.The most outstanding feature is
the application of Twin Square Wave Inverter Technology.

INSTALLATION & OPERATION
1.Connection of Input Cables
11. Pre-flow Gas Timer:
Provides pre-flow gas to purge tig torch
gas line prior to the initialization of the arc.
Adjustment is 0-2sec.
12. Welding Current Control:
For adjustment and setting of the main
welding current.
13. Base Current Control:
(Available Pulse Model Only) For the
adjustment and setting of the base current
in Pulse mode.
The set value is a percentage of the main
welding current.
14. Down Slope Control:
Approaching the end of the weld time the
welding current can be reduced gradually
until it stops, this prevents craters and pin
holes and is referred to as “down slope”.
This dial is for the adjustment and setting
of the down slope time.
Adjustment is 0-10sec.
Note: When using the remote foot control
set the dial to “0”.
15.Arc Force Control:
(Available Pulse Model Only). Applies
only in MMA mode. This dial adjusts the
characteristic of the welding arc from
forceful arc at maximum to soft arc at
minimum.
16.Pulse Frequency Control:
(Available Pulse Model Only). This dial is
for the adjustment and setting of the pulse
frequency when the machine is set in
Pulse mode.
Adjustment is 0.5-300Hz.
17. Pulse Width:
(Available Pulse Model Only). This dial
is for the adjustment and setting of the
on time of the peak current (pulse width)
when the machine is set in Pulse mode.
Adjustment is 10% – 90%.
18. AC Balance Control:
In AC TIG welding, the current exchanges
between positive and negative directions.
When current flow is from tungsten to
work piece it is in a positive (+) direction,
the arc energy is stronger at the tungsten
and is good for removing the oxidized
surface of the work piece. However too
much + current flow can drive too much
energy to the tungsten causing it to
overheat and melt the tungsten electrode.
When the current flow is from work piece
to tungsten it is in a negative (-)
direction, the arc energy is greater at the
work piece providing better penetration
and the tungsten heats up less. The arc
stability is good and ideal for most AC
welding situations.The dial is for adjusting
the current flow time between positive and
negative. When set at the middle the
proportion is 50%. When set at the
maximum it is 80% and at the minimum it
is 20%. Adjusted in a clockwise direction,
the positive current flow time is longer and
negative flow is less, and vice versa.
19. Post Flow Gas Timer:
This dial provides an after flow of gas
when the welding arc is extinguished.
Post flow gas prevents contamination of
the molten pool and tungsten
electrode during cool down cycle.
Adjustment 0-10sec.
