Single Timer - Multiple SCR Systems
The MedWeld 3005 control can be shared amongst multiple SCRs in a cascade circuit.
This system allows for individual control for each welding application by time-sharing
the welding processor.
Multiple Timers - Multiple SCR Systems
The MedWeld 3005 can be configured to take advantage of both the lower cost
cascade system and the rapid advantage of the multi control system. The drawing
above shows three separate cascades integrated together over three phases. These
cascade systems are distributed across Phase A (L1-L2), Phase B (L2-L3) and Phase C
(L3-L1).

Rather than sequencing 9 SCRs in
cascade fashion, the user in this case
has equipped his control with 3 timers
that cascade 3 SCRs each for a total of
9 SCRs. This enables the user to
balance the loads over three phases
and also reduce machine cycle time.
