Arcraft Plasma Equipments ( India ) Pvt Ltd are leading manufacturers of

Plasma Torches ( Both ID and OD ) Power sources , Positioners ,

Manupilators and related equipment used for PTA welding .


3/22

Powder Plasma welding

is widely used for

hardfacing , wear

resistance , corrosionresistance , impact

resistance besides

many applications in a

wide variety ofindustries.

The benefit of PPAW

or PTA is that it gives a

strong metallurgical

bond unlike manythermal spray

processes.


4/22

PPAW / PTA system

This is a complete systemconsisting of

Power source

Plasma torch with cables

Torch Oscillator

Controller

Water chiller andrecirculator

Positioner Torch Manupilator or

Column and Boom


5/22

Main Unit

This is the main unit whichalso has the Pilot arc systemfor striking the plasma arc.The main Power Source is areliable inverter basedsystem with indicators forCurrent and Voltage .

It also has Flowmeters forcontrolling thePlasma Gasand Sheilding Gas .

It has indicators andswitches for variousfunctions which will beexplained in more detail


6/22

Control console

Flowmeter for Plasma gas andShielding Gas

Power on /off switch withindicator

Indicator for gas flow with Testand Switch off function

HF/ Pilot arc test and switchoff function.

Water chiller on / off switch

Trip indicator for water and

gas failure 220 and 24 VAC Fuse in case of

current over drawing due tofault in electrical / electroniccomponents


7/22

Power Source

Power source fordelivering power to theplasma torch

Power source will be

selected depending oncustomers requirement /location and budget.

For export models we useLincoln ( USA ) power

source with current andvoltage display andinternational warranty ofthree years .


8/22

Plumbing Board

The Plumbing board has

all the fittings for water

, power and gas

connections to thetorch.


9/22

Powder feeder on /off

This panel gives 220

VAC supply to the

powder feeder and also

the on / off signal .

It has a floating auxillary

contact for external

interface if required.


10/22

Plasma Torch for surface applications.

400 Ampere heavy duty

PPAW torch with 8

meter cables for surface

applications.

Torch is fully servicable

with no moulded parts

for easy replacement.


11/22

Plasma torch for internal bore welding


12/22

Plasma torch for internal bore welding

This torch can do

service in internal bore

of pipes of minimum

diameter 75 mm and alength of 500 mm

continuosly . Longer

lengths can be

developed .

Torches are being

developed for even

smaller bores.


13/22

Controller


14/22

Controller

Controller has functionsfor controlling the torchmanipulator ( up,down ,left right of base )

Job positioner ( tilting ,rotation speed anddirection)

Pilot arcing and weld start

Programmes for torch

oscillation automaticweld sequence straightor circular.


15/22

Oscillator control

Oscillator stroke width

from zero to 25 mm

Speed of oscillation

upto 60 strokes perminute

Dwell time 0 to 9.9

seconds independently

adjustable on both

sides.


16/22

Linear weld in control

Cycle time

Stroke and speed of

straight weld

Step for number of

bands


17/22

Circular weld programme

Speed control of

rotational movement

Cycle count for stepover

of torch for number ofbands .

Overlap between two

bands can be preset as

required


18/22

Welding Positioner

Available in tilting or

fixed models upto .

Faceplate diameter and

weight bearing capacityas per customer

requirement


19/22

Torch Manupilator or Column and

Boom

Various models

available for height and

stroke length

Provison for oscillatormounting

Base can also move and

rotate manual or

motorised options


20/22

Powder Feeder

Hopper capacity of 5 kgs

Delivery capacity 5 kgsper hour

Positive displacement ofpowder gives smoothflow of powder withoutpulsing.

No need to place the

feeder above the torch asrequired by gravity basedfeeders


21/22

Torch Oscillator

Consist of stepper

motor with ball screw

mechanism for smooth

jerk free movement asper signal from

controller


22/22

Water Chiller cum Recirculator

Water chiller

refrigerator heat

transfer principle with

digital display of watertemperature .
