Weldman ‘H’ series inverter power sources deliver constant current (CC) DC power. This is achieved using energy efficient IGBT inverter technology. These machines render smooth and stable arc for Stick / MMA welding with various types of electrodes. The machines are designed and built with careful layout of power components and cooling arrangement. Hence, heavy duty welding at higher current is achieved.

Processes

Stick welding   >   Scratch start TIG welding   >   HF start TIG welding (with optional modification kit and HF TIG control unit)   >   Gouging

Features

• Light weight, compact and yet reliable.
• Designed and built to operate under harshest environment and meets the requirement of quality welding in shipyards, pipelines, construction, petro-chemical plants, oil refinery, offshore works and workshop.
• Generator friendly (low kVA requirement).
• Ease of maintenance.
• Welder friendly controls.
• Digital display for easy current setting.
• Step-less current control.
• Arc force adjustment to minimize the electrode sticking to the weld puddle.
• Built-in hot start for additional current during arc striking (can be adjusted by preset potentiometer in PCB).
• Suitable for voltage sensing (OCV driven) wire feeder.
• MCB for fault protection.
• Under voltage and Overload protection.
• Current limit.
• Control circuit protection by fuse.

Optional Items
