Thermatool solid-state welders with CFI2 achieve frequencies up to 800 kHz - the industry's broadest range. They require no output transformers, and deliver full output power from the RF welder under fluctuating loads, automatically.
Automatic speed / power control system adjusts weld power for mill speed changes and minimises unwelded tube when mill is started or stopped.
Programmable logic controller (PLC) provides adaptable handling of customer signals and fault diagnostics for rapid repair, minimising downtime.
Thyristor (SCR) power controller / stabiliser provides constant output power for consistent weld quality.
Low ripple filter network minimises AC line harmonics to less than 1%, standard, to eliminate "stitched" welds. Optional filters reduce ripples to less than 0.2% for welding stainless and non ferrous metals.
Heavy duty main power transformer provides reliable power output and long life.
Compact, sealed power cabinet may be located far away from the RF inverter to conserve space, without RF loss even over large distances. Removable doors and internal lighting enhance ease of maintenance.
AutoMatch Automatic load match system ensures maximum welder efficiency and consistent weld frequency for low cost operation and repeatable pipe and tube quality.
High-frequency high power capacitor bank delivers high power with low voltage to minimise arc-overs and enhance reliability
Water cooled high - frequency 50 kW module pairs minimise total power loss in case of module fault, and reduce time required for maintenance.
High-Current, low voltage CFI2 technology achieves frequencies of 400 Hz and above, the industry's broadest range.
Short circuit damage proof CFI2 technology ensures reliable operation through coil arc overs, minimises trip-outs, and is not damaged by short circuits.
