MECHANICAL
DESIGN
The
Workhorse provides exceptional ruggedness and durability
in demanding environments such as construction, shipbuilding and
offshore welding. The case is made out of fiberglass, which provides
sturdier resistance to dents and forces than a sheet metal case.
ELECTRICAL DESIGN
The
Workhorse uses an SCR inverter design for its power supply.
The inverter design allows for an industrial welding machine weighing
only 79lbs/36kgs. We have chosen the proven SCR component instead
of the IGBT to increase reliability. Indications from the market
show that SCRs are up to 100 times more reliable in welding applications.
TIG
Welding
The
Lift Start feature allows contact between material and electrode,
with no damage to the electrode, and is a low-cost solution for
TIG welding since no expensive high frequency or capacitor discharge
circuits are needed.
Smart
Hot Start
This
feature brings
the puddle temperature up quickly for good initial penetration.
The amount of Hot Start required is dependent on the weld puddle
temperature. The Workhorse measures the time in between
welds. The longer the period between stopping and starting, the
greater the Hot Start current. If the arc is broken for less than
a second, the Hot Start is eliminated. This prevents the puddle
from overheating and the weld burning through.
Arc
Force
This
allows the operator to adjust the current surge which results when
a drop shorts the arc.
Remote
Hand Control
Hand
operated remote control with 25 feet of cable.
Safety,
Warranty and Service
The
welding units are designed to meet UL551 and CE requirements.
The
units come with a factory warranty and user manual.
Service
will be taken care of by the factory or can in many cases be performed
locally by your service authorized Distributor.
