350 Microwelder. Its modern electronic controls help produce strong, homogeneous weld
patterns, even under the most difficult working conditions. Weldmax 350's precision func-
tion, which provides very short-duration pulses, permits ultimate control of tiny part weld-
ing. Unit features six push-button weld material selections and three push-button amper-
age selections for easy, automatic welding. Includes automatic operation override for man-
ual welding with up to 1,600 amps.
shrinkage. Weld material is minimal, which makes hand and machine finishing easier.
Hardening and plating can be done after welding. Only gentle pressure is required on weld-
ing electrodes, preventing the formation of cavities or pinholes.
Suitable for all forms of small mold damage. No need for other types of welding (e.g., argon
or laser welding). Safe and easy to operate--no special training necessary. No harmful weld-
ing fumes or toxic gases are emitted. No scaling or flaking occurs. High-quality welding alloys
are free of impurities to ensure resulting welds are reliable.
molds. For all steels, stainless steels and other ferrous metals. Not recommended for use on
press dies, and will not weld on aluminum molds.
· Building up parting lines, mold seams, three-point corners and edges
· Filling pores and repairing pinholes
· Eliminating characteristic holes, sags or pores following the argon welding process
· Repairing slides, ejectors, core pins, flat cores and mold edges
· Eliminating machining defects caused by milling, countersinking and wire EDM
· Modifying designs of inserts, cores and prototype molds
Input Voltage
a minute. As gentle electrode pressure is applied to the damaged area, these pulses fuse
metal powder, sheet or wire weld material to the mold under repair. Weld material con-
taining alloying properties of the ferrous metal being welded is first fused then welded into
the base metal by a systematic and controlled supply of amperage discharges. This process
builds up weld material, producing a strong weld that penetrates the mold surface. The
welding process can be fine-tuned by adjusting frequency of pulses and output current.
