Setting Up The Weld - Chicago Electric 62486 Owner's Manual & Safety Instructions

operating Instructions
fire resistant work clothes without pockets should be worn when welding. Light from the arc can cause
permanent damage to the eyes and skin. do not breathe arc fumes.
1. Place the Welder on a level surface that
can bear its weight near the work area.
Duty Cycle (Duration of Use)
Avoid damage to the Welder by not welding for more
than the prescribed duty cycle time. The Duty Cycle
defines the number of minutes, within a 10 minute
period, during which a given welder can produce
a particular welding current without overheating.
For example, this Welder with a 60% duty cycle at 165 A
welding current must be allowed to rest for at least
4 minutes after every 6 minutes of continuous welding.
Failure to carefully observe duty cycle limitations
can easily over-stress a welder's power generation
system contributing to premature welder failure.

1. Make practice welds on pieces of scrap the
same thickness as your intended workpiece
to practice technique before welding anything
of value. Clean the weld surfaces thoroughly
with a wire brush or angle grinder; there
must be no rust, paint, oil, or other materials
on the weld surfaces, only bare metal.

2. Connect a #12 AWG ground wire (not included)
to the Ground Post on the rear of the Welder
and route it to ground. If possible, ground
the workpiece independent of the welder.
This welder has an internal thermal protection system
to help prevent this sort of over-stress. When the unit
overheats, it automatically shuts down and the Overload
Indicator lights. The welder automatically returns to
service after cooling off. Rest the electrode on an
electrically non-conductive, heat-proof surface, such as
a concrete slab, well clear of the ground clamp while
allowing the welder to cool with the Power Switch on, so
that the internal Fan will help cool the welder. When the
welder can be used again, use shorter welding periods
and longer rest periods to prevent needless wear.

2. Use clamps (not included) to hold the workpieces
in position so that you can concentrate on
proper welding technique. The distance (if
any) between the two workpieces must be
controlled properly to allow the weld to hold
both sides securely while allowing the weld
to penetrate fully into the joint. The edges of
thicker workpieces may need to be chamfered
(or beveled) to allow proper weld penetration.
NOTICE: When welding equipment on a vehicle,
disconnect the vehicle battery power from both the
positive connection and the ground before welding.
This prevents damage to some vehicle electrical
systems and electronics due to the high voltage
and high frequency bursts common in welding.
