Adjustment of welding current
Stepless adjustment of welding current from min. to max. within a single range.
The current is controlled by movement of a screw arrangement fitted on the front panel.
Adjusted welding current is clearly indicated by a dial on the front panel of the
welding transformer.
Phase compensation
The THH 400 as well as the THH 630 are available with or without phase compensation.
Phase compensation may sometimes prove to be a good investment as the primary current
can often be reduced, resulting in reduced fuse size and cable diameter.
Movability
The THH 400 and 630 are as standard provided with wheels and handle. For transport with
lift-truck or crane, the transformers are also provided with lifting eyes.
