Cordless, IP54-sealed capacitive-discharge welder for on-site thermocouple repair. 500+ beads per charge, 2.9 kg, and a hand electrode pencil that reaches into installed assemblies.
US$890 indicative FOB · volume and DAP / DDP terms quoted on request
14.8 V / 5.2 Ah Li-ion pack delivers 500+ full-energy beads per charge. Recharge from any 100–240 V socket — or a vehicle inverter.
Foam-lined sealed case protects the welder, pencil and spares against dust, rain and vibration in a service van or on a plant floor.
Charge time at maximum energy is under 6 seconds, so a technician can keep a steady 8–12 bead/minute rhythm.
A slim 180 mm pencil reaches into burner assemblies, manifolds and panel-mounted sensors that a benchtop fixture cannot access.
Dial is graduated 0–50 W·s so the same setting reproduces the same bead on 0.1 mm or 1.0 mm wire.
Trigger and energy dial sit under one thumb — the other hand stays free to hold the workpiece.
