FABRICATOR 281
Manual No. 0-4880B - INTRODUCTION
2.04 General Information
The Fabricator 281 is a 208-230 Volt MIG machine with
a best in class performance of 300 Amp maximum
output @ 40% duty cycle, 24 voltage steps, digital
meter and dual cylinder racks. The completely separate
wirefeeder system has 26ft (8m) interconnection cables,
spool gun operation on demand and spot/stitch timers.
The wirefeeder, with fitted wheels, conveniently fits on
a pivot mount on top of the power source or can be
lifted off the pivot and carried up on top of equipment
or machinery up to 26 feet away. Additionally, the spool
gun connects to the wirefeeder allowing even further
distance. The Fabricator 281 is an extremely versatile all
round performer in its class.
The Fabricator 281 gives excellent performance on
mild steel, stainless steel, aluminum, silicon bronze
and some hard facing wires with Argon based shielding
gases. The Power Supply also gives excellent results on
mild steel using Carbon Dioxide shielding gas.
The Fabricator 281 is supplied as a complete package
ready to weld (apart from gas cylinder and electrode
wire). The following instructions detail how to correctly
set up the welder and give guidelines on gaining the
best production efficiency from the Power Supply.
Please read these instructions thoroughly before using
your Fabricator welder.
2.05 Safety
The following basic safety rules should always be
followed:
• Ensure the machine is correctly installed, if
necessary, by a qualified electrician.
• Ensure the Power Supply is grounded correctly
(electrically) in accordance with local regulations.
• Excessive heat in the welding cables may cause
fire. Never weld with poor electrical connections,
damaged welding cables or exceed the welding
cable current rating as this will produce excessive
heat and may cause a fire.
• Always wear the correct protective clothing for
protection from sparks, molten particles and arc
rays.
• When welding in confined spaces, always ensure
adequate ventilation and constant observation of
the operator.
• Keep combustible materials away from the
welding area. Have a suitable fire extinguisher
handy.
• Never watch the welding arc with naked eyes.
Always use and wear a welding mask fitted with
the correct filter lens.
• Do not stand on damp ground when welding.
For more complete safety advice please read section 1.
2.06 Protective Filter Lenses
Protective filter lenses are provided to reduce the
intensity of radiation entering the eye thus filtering out
harmful infrared, ultraviolet radiation and a percentage
of the visible light. Such filter lenses are incorporated
within face shields. To prevent damage to the filter
lenses from molten or hard particles an additional hard
clear glass or special plastic external cover lens should
be used. This cover lens should always be kept in place
and replaced before the damage impairs your vision
while welding.
Table 2-1: Filter lens size versus welding current
It is recommended to use a welding helmet, conforming
to the local relevant Standards when electric arc
welding. Use a welding helmet in serviceable condition
with the correct filter lens. Refer to Table 2-1 above and
AWS table in Section 1.
