6 Single-Sided Welding
Page 27
All Info Copyright © Pro Spot International Inc.
Single-Sided spot welding is used where Two-Sided spot welding cannot be used.
Important:
The Single-Sided spot welding is not permitted on supporting
frameworks of a vehicle. It is only permitted for cosmetic purposes.
1.
Select 1-4 Batteries in the ON position.
2.
Fit the Single-Sided Gun with Single-Sided electrode (
fig.6.9
).
3.
Grind between the inner and the outer body sheets to remove paint, primer and
rust. This ensures good electrical contact when performing Single-Sided welding.
4.
Ground the working area (
refer to section 6.1 "Single-Sided Welding
Overview"
).
5.
Apply about 33-44 lbs of pressure on the Single-Sided gun and push the trigger
to weld. Reposition and weld again.

Note:
Make sure that Single-Sided electrode is clean. If it isn't, use a file
or tip dresser to clean it. If the weld cap shows considerable wear, it
should be replaced
(refer to section 5.4 “Removing Welding Electrodes”)
Many of today's car bodies come with factory equipped threaded studs. After a collision,
the studs may be lost or do not accompany the replacement part. Withthe Hybrid Spot,
threaded studs can be welded-on in factory style. This type of stud is alsocommon
throughout the car body for attachments of interior, tail lights, door mold-ings, etc.
Studs are held in place during welding with magnetic adapter electrode.
1.
Select 1-2 Batteries in the ON position.
2.
Fit Single Sided gun with the magnetic stud adapter (
fig. 6.12
).
3.
Insert stud into the adapter (
fig. 6.12
).
4.
Prepare the surface area by removing paint and primer.
5.
Ground the working area (
refer to section 6.1 "Single-Sided Welding
Overview"
).
6.
Position single sided gun over work area and push the trigger to weld.
7.
Repeat as needed.

6.3 Bolt Welding
Tip:
A threaded stud can also be used to fasten the ground clamp directly
to the panel, minimizing the area needed for grinding.
Astuce:
Un goujon fileté peut également être utilisé pour fixer la pince
directement sur le panneau, ce qui réduit la surface nécessaire au broyage.
6.2 Single-Sided Spot Welding
Important:
Le soudage de Côté Unique par points n'est pas autorisée sur
les cadres de soutien d'un véhicule. Il est seulement permis à des fins
cosmétiques.
Remarque:
Assurez-vous que l ‘électrode Côté Unique est propre. Si
ce n'est pas, utilisez une lime pour le nettoyer. Si le bouchon de
soudure est considerablement usé, il devrait être remplacé (voir la
section 5.4 "Enlèvement d’Electrodes de soudage»)
