To prevent an electric shock, the user must
see the information in “Power Requirements” in page 3 and 5.
• The fast connections of the electrode holder and the ground
clamp are inserted and turned one quarter of a turn in a
clockwise direction in the outlets set in the front panel to
secure perfectly.
• Press the process selector to
set the welder working in SMAW
mode (coated electrode).
The upper LED in
the selector will light on.
Reverse Polarity ( A )
• Connect the grounding clamp cable to the negative (
-
)
output clamping screw of the welder.
• Connect the grounding clamp (
C
) to the work piece.
• Connect the electrode holder cable to the positive ( + )
output clamping screw of the welder.
This configuration generates more heat in the electrode,
which produce more penetration with basic electrodes,
making it ideal to weld thick pieces.
Direct Polarity ( B )
• Connect the grounding clamp cable to the positive (
+
)
output.
• Connect the grounding clamp (
C
) to the work piece.
• Connect the electrode holder cable to the negative ( - ) output.
This configuration generates more heat in the work piece, thus producing
less malformation in the work piece and narrower joints making it ideal
for thin pieces.
• Connect the power cable (
D
) to the power network to the work voltage
(127 V / 220 V ). The welding automatically detects the
working voltage (it is not necessary to make any type of connection).
Before using the welder it must be properly grounded.
You should not uninstall the ground wire as doing so will cause serious
bodily injury.
