| "Weldtronix" H.F. unit suitable for both AC/DC TIG welding process and is suitable for both Gas cooled as well as Water cooled TIG Torches. Unit is rated at 400Amp. |
| Introduction to process |
| It is a compact, portable TIG control unit which constitute a complete TIG Welding machine when connected to a stand MMAW Rectifier for Ferrous Metal (MS/Ss), Copper and non-ferrous (aluminum and its alloys) metals |
|
| |
| Features |
| • |
An electronical controlled unit which eliminates the use of costly and bulky HF and DC suppressor unit incorporated with solenoid valve to economize the costlier argon gas. |
| • |
Built-in feature of Pre-flow control to prevent the electrode oxidization at the start of weld. |
| • |
Electronically balancing the AC wave forms helps in total removal of oxide films during welding of aluminum and its alloys |
| • |
Superior Arc striking through a discharge of 10KV of High Frequency Voltage pulse |
| • |
Auto HF cut-off in Dc mode |
