This equipment is suitable for butt joint or fillet weld of pipe fittings. Diameter of circular workpiece: girth weld with customizable size. Example: straight pipe to straight pipe, straight pipe to elbow, straight pipe to tee, straight pipe to flange.
XD-GH400 is a 400A TIG girth welding power source with a built-in pipeline welding database independently developed and manufactured by KEPUNI. It integrates hardware and program control such as welding machine movement, control module, arc voltage tracking, welding gun swing, integrated wire feeding, printer module, Internet of Things module, USB download interface, etc. It can automatically generate all the parameters required for welding according to information such as pipe diameter and wall thickness. It is easy to operate and use.
Key Features:
Welding head design:
The
welding gun adopts the standard TIG 500A water-cooling design, which
can work continuously for a long time. It is equipped with an arc
voltage height adjustment device and a welding gun angle swing device,
which can be adjusted automatically or manually.
Wire feeding structure:
Adopts
V-shaped serrated wire feeding wheel and high-precision motor, which
can feed wire evenly and can feed 0.8mm-1.6mm welding wire without wire
sticking.
Protection function:
Overvoltage,
overload, leakage, arc ignition failure, tungsten needle short circuit
protection，air shortage alarm, defect detection.
Control function:
Current
control,frame 5-axis control,wire feeding control ,rotation angle
movement,arc pressure control, yaw control,printer control and
circulating cooling water control.
User-Friendly Design:
Siemens PLC+DSP digital signal control, more accurate arc output, 400A welder movement and high-frequency ring porcelain arc ignition technology, making it easier to arc.
The
circular automatic welding program with stable output current
automatically controls the current output, wire feeding speed, arc
voltage tracking, welding gun swing, positioner, circulating water and
other parameters.
Embedded pipeline welding V2.0 database, users only need to input pipe diameter, wall thickness or welding wire diameter, and the system can automatically produce welding parameters.
Built-in Internet of Things module can remotely upgrade the control program anytime, anywhere, and realize industrial interconnection with its own USB interface, which can be exported by users.
The
6-axis design allows the welding gun to be adjusted left and right, up
and down, and front and back to meet the welding requirements of various
pipe fittings.
