Stronghold welding machines set the standard for multi-purpose resistance welding equipment, having adjustable reach for spot welding. They are easily adapted for projection welding and are available as a seam welding version.
Standard Features for spot welding include:-
> ADAPTABILITY – Infinitely adjustable reach from 500-800mm.
> HIGH QUALITY WELDING – Choice of weld control.
> PRODUCTIVITY – Welding speeds up to 250 spots per minute.
> RELIABILITY – 50% duty cycle encapsulated transformer.
> VERSATILITY – Simple adaption to projection welding.
Stronghold can be fitted with a range of AC Weld Transformers (100 to 150kVA) or MFDC Transformers (100 to 250kVA) as well as a choice of Weld Controls and other options.
MFDC offers the following added benefits –
> Improved weld quality.
> Reduced Power consumption costs.
> Lower peak currents providing increased electrode life.
> 3-phase even load distribution.
> Ideal for welding coated materials and Aluminium.
> Weld times reduced through increased rate of heat input to work piece.
> Reduced weld splash owing to lower peak currents.
> Can be retrofitted to existing machines.
> Retract/high lift and or 160mm air cylinder.
> 100KVA , 150KVA single phase AC or 100KVA 3-phase DC Medium Frequency Transformer.
> Load Cell for Force verification
> Nut Verification System
> Water Flow Sensors
> Electro-pneumatic regulator for automatic adjustment of weld force with weld program selection. (Compatible weld control required).
> Manual or Inline versions available
> Linear Transducer for Head Travel position
> Closed circuit water cooled system.
> Integration of automatic nut and bolt feed machines.
