Features:
- Weatherproof Electrical cabinet.
- Robust DC motor for tractor movement.
- Fine adjustable manual cross slide for vertical & horizontal adjustment.
- Weld head slide assembly.
- Flux stored in Flux Recovery Unit as well as in Flux discharge hopper.
- View glass in flux hopper & in Flux Recovery Unit
- Same Power Source can be used for root welds and for FCAW / MIG / SMAW vertical welds.
- Two or more FCAW / MIG / SMAW welding heads can be used using one Power Source (by using Multi weld 350) which increases vertical welding productivity by more than double.
- Auto flux recovery unit.
- Auto sensor for wire feeder speed.
- Same mechanism can be used for Arc gouging.
- Ambient temperature range at which the machine can work: -5 to + 65 deg C.
- Machine is compact, lightweight & can be handled without the need for a large crane.
- Root welding with backing strip possible
- Astha AGW does the work equivalent to 6 welders
