Mount the camera to the torch and use the camera cable to connect the camera to the controller. To see the image, connect a large format monitor (i.e. HDMI monitor) or a laptop to the controller. Check that the camera is in focus and start welding! If you are using the zoom lens and LED, mount this assembly to the bench and power up the LED. The LED provides a bright image when welding is off. The torch mount allows for a close-up image at almost any viewing angle. This is the principal advantage of the MeltView APEX3 camera over other welding cameras. The torch mount is not suitable for imaging SMAW, since the stick is consumed during welding, so the bench mount with zoom lens is used to capture video of SMAW.

The APEX3 camera mounted to the torch can be as close as 2" to the weld for a field of view of ~2". In some cases instructors will mount the APEX3 with microlens to the bench instead of the torch and use the camera up to 16" away. For working distances 16" or greater, we recommend mounting the APEX3 camera with varifocal lens on the bench with the magnetic mount.

While cameras are everywhere nowadays, they are not designed for imaging the very bright welding arc. In fact, there are only a few cameras that can do this, and MeltTools offers the most well-designed camera for welding education on the market. Every MeltView welding camera is designed and built and supported from our facility in Michigan.

No, it’s not. Our customers report that it takes getting used to having a camera mounted to the torch, but that it's worth it for the quality of the images that they can capture. The APEX3 plus lightweight torch mount weigh 10oz, while the APEX3 plus C-clamp torch mount weigh just over 1lb. Both mounts are included in the kit and are workable given the weight and drag of a typical welding torch and cables.

No. Our kit is designed for easy setup and comprehension. The APEX3 does not need software to operate, making it quick to set up the system and to start using. A manual is also included which gives clear examples of how the system can be put together and used for welding demonstrations. Our support team at sales@melttools.com is ready to further help when needed.

No. The APEX3 does not have any integrated cooling system because it does not need one. The camera can ideally operate in temperatures up to 50°C (122°F) and cools off between welding demonstrations.

Our customers have visualized all of the following: Melt-in at the leading edge of the puddle; melt-in on the sides of the puddle; solidification of the rear of the weld puddle; effect of parameter changes, electrode position and traverse speed on weld puddle behavior and dimensions; generation of various weld defects; torch manipulation techniques.

Additional cameras can be synchronized with the APEX3 camera. The video resolution can be set as required by life display, recording or streaming requirements and the size and position of the different cameras configurable on the screen layout configured as desired. See https://www.youtube.com/watch?v=XqKyTFfWb0M for an example.

Yes, the kit ships with a directional microphone and will display, record and stream the synchronized sound.
