3. Operation
3.1 Stud Welding Recommendations
Please review the following stud welding recommendations before
operating this equipment. They contain information important to
achieving good welds.
1.
Welding components and workpieces need to be suitable for
welding. Only use material combinations which are specified in
the operating and service instructions.
2.
The welding zone should be smooth and have a bright, metallic
finish. Care must be taken not to exceed a welding zone
coarseness of 80µm.
3.
Impurities in the welding zone such as rust, forging scales,
moisture, grease and oils need to be removed prior to
commencing welding. Anodized workpiece surfaces must be
ground to remove anodizing from weld zone.
4.
Workpieces made of aluminum or workpieces with aluminum
coating may only be cleaned with a stainless wire brush or
scraper to prevent contamination of the aluminum surface.
5.
Workpiece should be stationary, and free of vibration. (particularly
important in case of large and thin-walled workpieces).
6.
Chlorous solvents must be removed from the welding zone.
They may not be exposed to the arc radiation.
7.
Poor welding quality as a result of arc blow can be avoided by
careful grounding techniques, such as using multiple grounding
clamps, and symmetrically positioning the grounding clamps.
8.
Ensure that there is solid contact (low resistance) in all
connection points in the welding circuit (welding cable
connections
– chuck – grounding clamps).
9.
Lay out the welding and workpiece ground cable without loops
or snarls to minimize unwanted electromagnetic effects.
10.
Check the settings of the N1500i welding unit, and the setup of
the connected gun.
11.
During the brief stud welding process, maintain the position of
the weld gun and the workpiece.
12.
Welding on one workpiece with several welding units should be
avoided, if possible. If welding on one workpiece with several
welding units cannot be avoided, it is not recommended to weld
simultaneously.
13.
TIG welders are known to generate high frequency electrical
interference, and so they must not be used on the same
workpiece as the N1500i.
