Welding
1.
Select the right welding process based on the type
and condition of the pieces to be welded; the
environment in which welding is to be done; and
the desired finished appearance of the weld.
2.
Select and install the welding wire to match the
process. Use Genuine Lincoln Electric Brand wire.
Wire quality is essential for successful welding.
3.
Install the drive roll, contact tip, and nozzle
appropriate for the weld process.
4.
Check that the polarity is correct for the welding
wire being used and that the gas supply, if
required, is turned on.
Electromagnetic Compatibility (EMC)
This machine has been designed in accordance with all relative directives and norms. However, it may still generate
electromagnetic disturbances that can affect other systems like telecommuni cations (telephone, radio, and television) or
other safety systems. These disturbances can cause safety problems in the affected systems. Read and understand
this section to eliminate or reduce the amount of electromagnetic disturbance generated by this machine.
This machine has been designed to operate in an industrial area. To operate in a domestic area it is
necessary to observe particular precautions to eliminate possible electromagnetic disturbances. The
operator must install and operate this equipment as described in this manual. If any electromagnetic
disturbances are detected the operator must put in place corrective actions to eliminate these disturbances
with, if necessary, assistance from Lincoln Electric.
Before installing the machine, th e operator must check the work area for any devices that may malfunction because of
electromagnetic disturbances. Consider the following.
•
Input and output cables, control cables, and telephone cables that are in or adjacent to the work area and the
machine.
•
Radio and/or television transmitters and receivers. Computers or computer controlled equipment.
•
Safety and control equipment for industrial processes. Equipment for calibration and measurement.
•
Personal medical devices like pacemakers and hearing aids .
•
Check the electromagnetic immunity for equipment operating in or near the work area. The operator must be sure
that all equipment in the area is compatible. This may require additional protection measures.
•
The dimensions of the work area to consider will depend on the construction of the area and other activities that are
taking place.
5.
Refer to above Figure. Connect the work clamp to
the metal to be welded. The work clamp must
make good electrical contact to the work piece.
The work piece must also be grounded as stated in
Welding Safety Precautions in the beginning of this
manual.
6.
Based on the welding process type and material
thickness of the work piece, set the correct wire
speed and heat range setting.
7.
Based on the weld joint type and orientation of the
weld joint, position the gun into the joint at the
correct angel.
8.
To begin welding, raise your hand shield to protect
your eyes and pull the trigger.
9.
While welding, travel at a constant speed and
maintain an electrode stickout of 9 mm. Follow the
correct direction of travel for the process and joint
type and orientation.
10. To stop welding, release the gun trigger.
11. When no more welding is to be done, close the
valve on the gas cylinder (if used), momentarily
operate the gun trigger to release gas pressure,
and turnoff the machine.
Cleaning Tip and Gas Nozzle
Clean the contact tip and gas nuzzle to avoid arc
bridging between them. Bridging can result in a shorted
nozzle, poor welds and an overheating gun. Anti-stick
spray or gel, available from a welding distributor, may
reduce buildup and aid in spatter removal.
