|
|
|
Construction |
| |
Heavily fabricated
with streamlined appearance,
suitably stiffened at points
of stress. The transformer is
mounted directly on to the body
and the bearings for the arm
are provided in the same.
|
| |
|
|
|
Cooling
system |
| |
Electrodes,
electrode holders water cooled,
water required to be free from
residue forming impurities and
at a temperature of less than
30C. If water temperature is
higher, increased water flow
is required.
|
| |
|
|
|
Electrodes |
| |
One pair
Morse Taper II straight electrodes
supplied as standard with the
machine. Other types available
on request.
|
| |
|
|
|
Adjustment
of Electrode Force |
| |
By means
of air pressure. The force is
adjustable and gives a constant
force from 1-5 kg Cm by Pneumatic
Cylinder, adjusted by Regulating
Valve.
|
| |
|
|
|
Adjustment
of electrode stroke |
| |
By
vertical adjustment of electrode
holder. |
| |
|
|
|
Current
Control |
| |
By means
of 6 tap change links between
50% and 100%.
|
| |
|
|
|
Weld
Initiation |
| |
By means
of Foot Switch which initiates
the weld only after the pre-set
pressure id built up.
|
| |
|
|
|
Electronic
Control |
| |
Thyristorised
synchronous electronic sequence
timer consisting of: Sqeeze,
weld, forge, off and heat control
uint range 1-99c/s.
|
| |
SOLID STATE:
3 Timers provided for squeeze,
weld & forge Timings - Short
range 5-50 cysles. Longe Range
