Installing the Ground Cable and Clamp for Solid Wire MIG with Shielding Gas
MIG (DCEP) (Illustration MIG DCEP)
• Locate the Ground Clamp with Cable and connect the plug on the cable end to
the ( – ) connector on the Front Panel of the Welder. To connect the plug, line
up the key on the plug with the keyway on the socket of the Welder, insert the
plug and twist Clockwise until it is tight (FIGS 6 & 8).
• Attach the MIG Torch connector to the MIG/TIG Torch connection on the Lower
Left Front Panel. To connect the plug, line up the key on the plug with the
keyway on the socket of the Welder, insert the plug and twist Clockwise until
it is tight (FIG 6).
• Install the Polarity Jumper Lead into the ( + ) connector by inserting the keyed
brass connector and rotating to lock in place (FIGS 6 & 8).
Changing the Polarity
To use a Flux Cored wire, the Polarity must be changed to the DCEN configuration:
ELECTRIC SHOCK CAN CAUSE INJURY OR DEATH!
• Disconnect Welder from power supply before beginning.

• Remove the Ground Clamp Cable connection from the lower Front Panel
by rotating and pulling out.
• Install the Ground Clamp Cable connector by inserting the keyed brass
connector into the ( + ) connector and rotating to lock in place (FIGS 6 & 8).
Install the Polarity Jumper Lead into the ( - ) connector by inserting the
keyed brass connector and rotating to lock in place (FIGS 6 & 8).
INSTALLING THE SHIELDING GAS SUPPLY
BUILDUP OF GAS CAN INJURE OR KILL!
• Shut off gas supply when not in use.
• Ensure adequate ventilation
• Do not weld in confined areas.
• Always turn your face away from valve outlet when opening cylinder valve.
CYLINDERS CAN EXPLODE IF DAMAGED!
Shielding gas cylinders contain gas under high pressure.
If damaged, a cylinder can explode. As gas cylinders are
a normal component of the welding process, use extra
care to handle them carefully.
• Protect compressed gas cylinders from excessive heat, mechanical shocks, physical damage, slag, open flames, sparks and arcs.
Keep away from any welding or other electrical circuits.
• Install cylinders in an upright position by securing to a specifically designed rack, cart or stationary support to prevent falling or tipping over.
• Never weld on a pressurized cylinder or explosion will occur.
• Use only correct shielding gas cylinders, regulators, hoses and fittings designed for the specific application; maintain them and all related
components in good condition.
• Keep protective cap in place over valve except when cylinder is in use.
• Use proper equipment, procedures and have adequate help when moving or lifting cylinders.
