Using these workpieces is straightforward. First, pick the right type of workpiece for your welding simulation on the AugmentedArc. Place it correctly according to the joint it represents, like aligning the pieces for a butt joint or setting them at 90 degrees for a t - joint. When using the V - Groove Workpiece Kit, add the extra workpieces to the AugmentedArc package as needed for NCCER exercises. Make sure to handle the workpieces gently to avoid any damage. After use, clean them with a soft cloth to keep them in good condition. Store them in a dry place away from moisture to prevent rusting. And always refer to the full spec sheet for detailed technical information.
