Increase mold life and reduce repair costs dramatically. This powerful microwelder allows you to repair all forms of minor mold damage quickly and easily. Uses short, controlled amperage discharges to weld metal powder, sheet or wire to molds. Produces strong, homogeneous welds, even under difficult working conditions.

Features two welding functions: standard for small welds and precision for tiny welds. Includes three push-button output selections and six push-button material selections for automatic welding, as well as override option for manual welding, which lets you fine-tune pulse frequency and output current.

Weldmax 350 emits no heat beyond the repair area, so it causes no metal stress, distortion or shrinkage. Minimizes weld material consumption to reduce final finishing time. Works best with gentle electrode pressure, discouraging the formation of cavities and pinholes. Produces clean welds that will not scale or flake. Eliminates the need for other types of welders (e.g., argon and laser welders). Gives off no harmful fumes. Requires no special training to operate.

Welds all steels and stainless steels, as well as other ferrous metals. Will not weld aluminum. Suitable for use on molds and dies for plastics and rubber, die-casting molds and compression molds. Not recommended for use on press dies.
