POWER-UP SEQUENCE
1.
Check that the electrode polarity is correct for the process being
used, then turn the power switch ON. The fan will come on and
stay on until power to the machine is removed.
2.
Configure the machine for the desired process and application.
T
he
user can select one of the desired processes
and
t
he diameter of the
electrode they have chosen. After the diameter select, the user
will
have an opportunity to select the thickness of material they
intend to
weld. With these inputs the interface will determine the
best settings
for the selected input values.
3. Press the trigger to feed the wire electrode through the gun and
cable and then cut the electrode within approximately 3/8"
(10 mm) from the end of the contact tip.
4. If shielding gas is to be used, turn on the gas supply and set the
required flow rate (typically 25-35 CFH; 12-16 liters/min).
5. When using an Innershield electrode, the gas nozzle may be
removed and replaced with the gasless nozzle. This will provide
increased visibility and eliminate the possibility of the gas nozzle
overheating.
6. Connect the work cable to the metal to be welded. The work clamp
must make a good electrical contact with the work. The work must
also be grounded as stated in “Arc Welding Safety Precautions.”
