5. APPLICATIONS
5.1. A nail or washer, depending on accessibility, is welded to damaged panel to enable the panel to be pulled back into shape with the
slide hammer (figs 3 & 4). The washer electrode (fig.1.6) has a magnet to hold the washer in place prior to welding and should be used in
conjunction with extension electrode (fig.1.9 & fig.2). When reshaping is completed, cut and grind off nail or washer to give a smooth
finish.
5.2. The heating electrode (fig. 1.8) is used to locally heat and shrink out minor panel defects.
This electrode should be used in conjunction with extension electrode (fig.1.9).
6. OPERATION
WARNING: Ensure that you read and understand the safety instructions in Section 1.
Introduction
If you are not familiar with the SR20 or with stud welding, we recommend that you practice the
following procedure before attempting any actual task. When welding, you will find that the trigger
operation time is very short. Leave approximately 1 minute between each use to allow gun to
cool. Practice on a scrap panel before attempting the actual work. Proceed as follows:
6.1. Welding
6.1.1. Disconnect from power supply. Screw side handle to left or right side of gun, as
required.
6.1.2. Attach the appropriate electrode (see Section 5). If using either of electrodes
(figs 1.6 & 1.10) also fit extension electrode (fig.1.9); see fig.2.
Note: Electrodes are copper, DO NOT over tighten or threads will be damaged.
6.1.3. Ensure you check the following before you start:
a). Electrodes and extension electrode must be clean and without defect.
Carefully remove any defect with a fine file or abrasive paper.
b). If the electrode is too worn and cannot be repaired, replace with a new one.
c). The panel to be welded must be clean and free from paint, grease or rust.
6.1.4. Connect the welder to the power supply. Select the item for welding (i.e. nail,
washer etc.) and insert into the electrode.
Note that washer and rivet electrodes are magnetic to hold washer/rivet in place.
6.1.5. With moderate force, press gun onto damaged panel surface. The electrode will
retract and the outer rim of the carrier (or extension electrode if fitted) will make
contact with workpiece thereby completing the electrical circuit. Keep the gun head
at right angles to the panel surface to ensure good contact (fig.3).

6.1.6. Squeeze the trigger for no more than half a second, so as not to overheat the fitting to be welded. This could ‘cook’ it and make it less
resistant against being ripped out.
DO NOT keep the gun in place for too long as it may overheat or burn a hole in the panel.
6.1.7 DO NOT release the pressure on the welding surface until you have released the trigger or the circuit may be prematurely broken.
6.1.8. Allow 1 minute between applications to allow the welder to cool down.
6.1.9. When the task is complete, disconnect the tool from the power supply and store in a safe area.
Note: DO NOT use the welding gun continuously for long periods, as the gun may overheat.
6.2. Slide Hammer
6.2.1. Grip the nail in the slide hammer spindle and then operate the striking hammer until the dent is pulled out. To pull a washer, grip the
washer hook (fig.1.7) in the spindle and hook the washer. See fig.4.
6.3. Sheet Heating
Use the heating electrode (fig.1.8) and extension (fig.1.9), for localised sheet heating in order to shrink and remove small dents
and pimples. Proceed as 6.1. above, omitting 6.1.5. Carefully heat the localised area accordingly.
IMPORTANT; If the electrode, electrode holder, carrier contact face (fig. 4.A) and panel are not clean, dry and free from paint,
grease, rust etc. the weld will be poor and the welder may overheat, causing irreparable damage to the casings.

7. MAINTENANCE
WARNING: Unplug from the mains power supply before performing maintenance or service.
7.1. Check all electrical components as stated in Section 1.
7.2. Using a cloth or a brush, regularly clean the transformer cooling slots.
7.3. Replace or repair damaged parts. Use recommended parts only, unauthorised parts may be dangerous and will invalidate the warranty.
7.4. Keep the handgrips of the welder dry, clean and grease free.
7.5. Always keep the surfaces of the electrodes and of the electrode holding barrels free from any oil, grease, dust, paint, etc., in order to
allow proper flow of current.
7.6. After you have finished using the gun, allow it to cool and then return it, and the accessories, to the case for safe storage.
