IMPORTANT! Single sided spot welding is not permitted on supporting
frameworks of a vehicle. It is only permitted for cosmetic purposes.
IMPORTANT! The outer sheet must be the thinnest sheet when
performing single sided spot welding. The thickness of the outer sheet to be
welded must be less than 1.5 mm, and the thickness of the inner sheet must
be less than 2 mm.
IMPORTANT! When not in use, be sure to place the multi-function gun
and the ground connector so that they do not make electrical contact. Risk
for short circuit.
Fitting the multi-function gun with a single side electrode
1. Release the lock nut on the multi-function gun by hand or with a
wrench to open the tool holder.
2. Make sure that the tip of the single side electrode is rounded. For
changing the electrode, see section "Changing the single spot
electrode" on the following page.
3. Insert the single side electrode and the electrode holder into the tool
holder.
4. Lock the tool holder by tightening the lock lock nut.
NOTE: To achieve a quality weld nugget it is important that the tip of the
single spot electrode is evenly rounded. It is also important that the tip of the
electrode is rounded.
A used electrode can be sharpened using a electrode tip dresser. Place the
electrode into the drill chuck. Rotate the drill chuck and grind the electrode
tip using a electrode tip dresser.
NOTE: The electrode, not the file, shall rotate when sharpening the elec-
trode.
