HW 300 is a professional DC welder with capacity of
300 Ampere powered by hydraulic motor, machine
can also be used as generator with three single
phase.
HW300 gives low cost welding capacity and
electricity obtained from the hydraulic circuits of
excavators, trucks, mobile work shops, service
vehicles and all machines with sufficient hydraulic
capacity.
The welding current can be fine regulated to give the
precise capacity needed in professional welding
works.
Hydraulic functioning means : quietness, safety,
reduced weight and space, no need of extra fuels ,
easy transportability, robustness, absence of
vibrations and exhaust smokes, minimal
maintenance necessity.
HW 300 increases the versatility of the machines and
eliminate all problems associated with traditional
engine powered welders.

TOOL IS DELIVERED INSTALLED ON A STEEL SUPPORT FIXED BY SHOCK MOUNTS HIGH QUALITY COMPONENTS
EXCLUSIVE GEAR MOTOR PROTECTED BY HYDRAULIC VALVE AGAINST EXCESS OF FLOW / SPEED - SUDDEN
BLOCK OF ROTATION - REVERSED ROTATION
VOLTMETER ALLOW TO VISUALIZE CORRECT SETTING AND SPEED
WELDING CURRENT CAN BE FINE ADJUSTED TOHAVE IDEAL WELDING PARAMETERS
