When restarting work, tapping
the base metal with theelectrode.

The engine welder will
restart automatically.
Then resume welding works.

DROOP (Drooping characteristic):
For stick welding and if you want tochange the conditions by the arc length.

CC (Constant Current characteristic):
For stick welding and if you want to dostable welding.
CV (Constant Voltage characteristic):
For semi-automatic welding. (Wire Feeder)

CC(Constant current characteristic)
Even when the arc length
becomes long and thus the voltage rises,
the current remains same.

e-mode(3 Position)––

Non-stick welding function

SOFT:
Pipe welding and welding in all types of positions.
Able to get the end result looks more manicured because of the less spatter.
HARD:
Overlay welding, Underwater welding, Arc air gouging.
Makes arc start easier.
(Prevent the electrode form getting stuck on the base material.)
STANDARD:
Fillet welding. If you are ever in doubt, choose “STANDARD” .

Welding Mode Selector switch: DROOP/CC/CV

Denyo engine driven welders can be used for welding by two operators at the same time.
This helps reduce purchasing costs for welding machines and contributes
significantly to work efficiency improvements.

AVR&

Inverter Can also be used as generators

Able to do double-duty at all kinds of work sites.
Denyo Engine Welders can provide high quality electricity.
It can be used for the power source for the precision machinery such as computer.

SAFE and SECURE“Non-stick welding function” can improve work efficiency.
Easy to remove the electrodefrom the base metal even if
the short-circuit occurs andthe electrode sticks to thebase metal.
Not only that, it can prevent
accidents if the short-circuit
occurs while operators areaway from at site.

Smart Stick“Voltage Reductoin Device (VRD)” .
Reduce the risks from incidental disasters ofelectrical accidents. So workers can work evenworking in high places or in high humidity with relief.
