ARC Welding Machine 630A 2ph (Transformers & Fematic Welding) THH630 : Esab Transformers for Industrial and Fematic Welding

·         Outstanding Quality

·         High Capacity

·         Excellent Welding Properties

·         Sturdy Design

·         Exceptional Reliability


THH 630

is manual welding transformers for industrial use with coated electrodes featuring high capacity and excellent welding properties. The high open circuit voltage ensures easy striking and re-striking action. Due to the high permitted loads, these transformers are ideal for Fematic welding.

Adjustment of Welding Current

Single stepless range with clearly visible indicator on the front panel.

Phase Compensation

THH 630 is available with or without phase compensation. Phase compensation may sometimes prove to be a good investment as the primary current and the rated output can often be reduced, resulting in reduced fuse size and cable diameter.


THH 630 as standard is provided with wheels and handle. For transport with lift-truck or crane, the transformers are also provided with lifting eyes.
