2-1. Basic Machine Safety Information
(1) Input power is AC110 or AC220 ≥15A.
(2) Turn the switch “off “ when machine is not in use.
(3) Make sure to turn the switch “off “ when connecting or removing cables from the machine.
(4) When performing machine maintenance or repair the switch must be turned “off “ after 5 minutes.
(5) The stud clamp is inside the stud welding torch. The inside diameter of stud clamp must be suitable for the stud screw.
Do not use worn stud clamp.
(6) Stud welding may cause welding arcs and metal spatter, use appropriate safety protection and goggles.
(7) Make sure there are no flammable materials in the work area.
(8) The machine uses a special stud screw, use only original manufacturer parts.
(9) Pleases contact the manufacturer for the following situations: mechanical failure, reduce or increase the torch cable,
changes to the standard equipment.

2-2. Stud welding and spot welding
2-2-1. Stud welding
When mounting the stud, the stud must extend past the three support legs about 2mm. Confirm the stud welding position.
Press the support legs on the work piece firmly. Make sure the work piece is smooth and clean. Press the torch trigger.
The stud screw will be welded on the base metal immediately. Check the stud welding strength. If the strength is not
sufficient, adjust the torch pressure, recharge, and repeat the steps. Traditional method such as rivets, lock screws, and
common welding typically damages the base metal. The stud welding process does not damage the base metal.
Using this specific welding function heat will not affect the back side of work piece. The back of the work
piece will have a good appearance.
2-3. Stud welding visual test
Please refer to the pictures below for stud welding results. If the stud welding results are unsatisfactory adjust the power,
torch head pressure, or torch head height according to the instructions. (Note: only adjust one parameter at a time.)

2-4. Stud Welding Troubleshooting
(1) The ground cable or base metal are not making a good connection.
(2) Torch cable or ground cable is winding, coiled up, or crossed. Cables must be straight.
(3) The diameter of screw clamp and stud screw is not suitable, or screw clamp is worn.
(4) The base metal is dirty, rusty, painted, or other problem interfering with electricity conductibility.
(5) The torch is not suitable for the base metal or stud screw (material or diameter).
(6) The stud screw and the base metal are not making a good connection. (Keep the stud screw contacted to the base
metal vertically 90 degrees).
(7) The stud welding voltage is not correct.
(8) The capacitor is damaged, or limiting voltage.
(9) Welding torch must not have movement when welding. All feet must contact base metal.
(10) Stud screw extends too long or too short from the stud clamp.
(11) Base metal has distortion, dented or has moved while welding.
(12) Method for connecting the ground cable:
1. Cable must connect the base metal directly. Two ground cables must be connected.
2. The ground cable must connect to the diagonal position of the base metal. (Refer to the diagram as follow).

2-5. Welding cable connection
Note:
1). The torch cable and ground cable uses Euro type quick connectors. Push the plug to the end of the socket, torch cable
to “Torch” socket, ground cable to “Ground” socket, and turn right to lock connection.
2). The input cable and control cable connectors have screws. Lock the screw to fixed the
connector.
3). The ground cable must be a clamped to the base metal.
4). All cables must be kept straight .If the cable is winding it will imact with the stud welding performance.
For cable connections refer to the diagram.
