Mobi Weld™ generates 110 volt DC which means
it can run any universal motor (any motor that has carbon brushes).
Such tools include grinders, drills, saws, sanders, impacts, heaters,
coffeepots, blenders, hot plates, halogen lights, incandescent lights
and air compressors with universal motors (Sears Craftsman #15234 with
the 1.5 HP)
The 55 amp Bosch alternator generates maximum welding
amperage equivalent to 120 amps. The 90 amp Bosch generates maximum
welding amperage equivalent to 180 amps and the 140 amp Bosch generates
a maximum welding amperage equivalent to 250 amps, all at 100% duty
cycle.
Because Mobi Weld™ is powered by an alternator,
the DC current's frequency is higher than that of a conventional welder.
Consequently, the #4 welding cables can be longer than the typical stationary
welder with little inefficiency.
What are the advantages/disadvantages of a standard/piggy
back installation?
When engine compartment space is premium, the piggyback
installation may not be an alternative. The Mobi Weld™ Bosch alternator
was manufactured to provide normal battery charging capabilities as
well as welding/generation output. However, when the power unit is switched
from 'Normal' to the "Power" position, the battery is no longer
being charged. Therefore, after 50-60 minutes in the "Power"
mode, the unit should be switched back to the "Normal" mode
to top off the battery for about 5 minutes. When a piggyback installation
is utilized, the unit is not used to charge the battery and can be run
continuously; the only limitation being the fuel in the gas tank.
Will the alternator deteriorate with excessive use
as a welder?
No. The Bosch alternator is designed to self saturate
and shut itself down in the event of short circuit conditions, preventing
any damage from taking place. When the unit is switched to the "Power"
mode, it simply draws 90 amps from the alternator that was designed
to produce 90 amps. Bosch alternators utilize press-fitted, very robust
diodes. This allows for efficient heat dissipation and cooling. Welding
with Mobi Weld™ doesn't tax the alternator any more or less that
driving the vehicle.
How can a Bosch 90 Amp alternator take the place
of a 120 Amp alternator?
The Bosch 90 amp is a "hot" rating. This
means that when you run your vehicle and the alternator becomes hot,
the output is still 90 amps (if needed). American alternators utilize
a 'cold' rating. However, when a vehicle runs it becomes very hot and
the alternator is less efficient when its hot. Therefore, the actual
output of the alternator is 70% to 80% of its "cold" rating.
Remember that an alternator's output doesn't necessarily correlate to
a vehicle's amperage needs. It depends on the accessories and the amount
of amperage they collectively draw.
Why is the Bosch 90 Amp more reliable than other
welders that utilize "high-output" 160-200+ amp alternators?
The Bosch 90 amp is engineered not only to produce
90 amps but also to cool efficiently and properly while producing 90
amps. If the amount of windings within the alternator are increased
in order to generate 160+ amps, then the size of the alternator must
also increase to allow for proper cooling. Without a substantial increase
in the physical size of the alternator, such a "beefed up"
alternator is subject to chronic cooling difficulties, especially when
a welding machine taps it for maximum amperage. Consequently, these
"high-output" alternators can be unreliable because they may
overheat and fail! The Mobi Weld™ pulls 90 amps from an alternator
that was engineered to produce 90 amps, then kicks the power box using
solid-state technology to produce welding power, like 110 current and,
most importantly, reliable battery charging during day to day driving.
A reliable alternator is key!
Why is the MobiWeld™ power box more reliable
than other welders on the market?
The Mobi Weld™ power box utilizes transformers
and a printed circuit board. The printed circuit board acts as the brain
of the system by controlling the LED indicator lights, automatically
shutting down the Mobi Weld™ in case of malfunction and insuring
that all components are performing properly. We use solid state technology,
no moving parts. Other units on the market utilize capacitors that have
limited life spans, solenoids that can stick, and technology that lacks
any kind of regulation. Without regulation integrated into the process,
the first indication of a problem is a catastrophic failure. Not with
Mobi Weld™. The printed circuit board activates the LEDs that indicate
Mobi Weld's status, always keeping the user informed.
Does the power box have to be mounted in the engine
compartment?
The power box can be mounted in the engine compartment,
under a seat or in a truck bed utility cabinet. Using heavier gauge
wire and cables, the power unit can be mounted anywhere on the vehicle.
When out of the warranty period, can the alternator
be easily serviced?
The Bosch alternator provided in the Mobi Weld™
package utilizes over-the counter Bosch components that can be serviced
at any alternator repair facility that services Bosch components. Remember,
we don't alter the original engineering that makes Bosch so reliable.
Its in the power box where the amperage is stepped up using a worldwide
patented process that sets Mobi Weld™ apart.
