Advantages
Large scale reduction in KVA demand
Welding of similar and dissimilar metals possible.
No water cooling required for electrodes
Installation and operating cost of the machine is less.
Machine can run on Genset
Weld joint free of blackening and distortion
No effect of voltage fluctation on weld quality.
Welding of heat sensitive parts is possible.
Minimum heating of components during welding.
As there is no heating of electrodes and no water cooling is required, cost of manufacturing and maintenance of fixtures and electrodes is reduced considerably.
All recommended electrode materials are suitable for these welders.

The Spot / Projection welding machines manufactured by Artech operate
on the principle of Capacitor Discharge.
The welders use mains input power only for control and charging
the Capacitors that store the energy. The built in controls ensure that the stored energy is
always constant irrespective of voltage fluctuations. The demand on input power, required
for charging of capacitors is less. This results in large scale reduction of KVA demand and
hence reduction in operational cost. The number of units consumed are also less as
compared to conventional welders.
The stored energy is discharged into the weldment via a pulse transformer and
the weld is carried out in a few milli seconds. In this process only the actual welding area is
molten and fused together. The welded parts are clean and undistorted as there is
insufficient time for heat to conduct beyond the welding area and the result is smooth finish
with minimum blemish.
The welders use fabricated frame structure for housing the capacitor
banks, control circuits, charging and discharging transformers. The welding electrodes are
mounted in C- shaped quick response press mechanism and electrode movement is
hydraulically / pneumatically operated.
Artech manufacturers machines ranging from 500 wattseconds ( joules)
to 30000 wattseconds ( joules ).
