POWER SOURCE
CONNECTION
WARNING
High voltage danger from power
source! Consult a qualified
electrician for proper installation of
receptacle at the power source.
• This welder must be grounded while
in use to protect the operator from
electrical shock. If you are not sure if
your outlet is properly grounded, have
it checked by a qualified electrician.
Do not cut off the grounding prong or
alter the plug in any way and do not
use any adapters between the
welder's power cord and the power
source receptacle.
Make sure the POWER switch is OFF
then connect your welder's power cord
to a properly grounded 120 Vac, 60 Hz,
single phase, 15 amp power source. Do
not operate this welder if the source
voltage is less than 105 Vac or greater
than 132 Vac. Contact a qualified
electrician if this problem exists.
Improper performance and/or damage to
the welder will result if operated on
inadequate or excessive power.
EXTENSION CORDS
For optimum welder performance, an
extension cord should not be used
unless absolutely necessary. If
necessary, care must be taken in
selecting an extension cord appropriate
for use with your specific welder.
Select a properly grounded extension
cord that will mate directly with the ac
power source receptacle and the welder
power cord without the use of adapters.
Make certain that the extension cord is
properly wired and in good electrical
condition.
Extension cords must fit the following
wire size guidelines:
• 0-25 ft. requires #12 gauge
• Do not use an extension cord over 25
ft. in length
SELECTING THE WELDING
WIRE
This welder uses only four inch spools of
0.030 inch (0.8mm) self shielding flux-
core wire, AWS classification number
E71T-GS. Steel from 18 gauge up to
3/16 inch thick can be welded with this
wire.
NOTE:
• Metal thinner than 18 gauge cannot
be welded with this machine.
Attempting to do so will cause burn
through (blowing holes) in the metal
you are intending to weld.
• If a spool has developed heavy
oxidation, the only solution to the
problem is to discard the spool of wire.
If you have an oxidized spool of wire, do
not discard it until you have unspooled a
few turns of wire to see if the wire further
down on the spool is in usable condition,
if not, - discard the spool.
INSTALL THE WELDING
WIRE
WARNING
Electric shock can kill! Always turn the
POWER switch OFF and unplug the
welder's power cord from the ac power
source before installing wire.
