WAVEFORM ARC PHYSICS

The Digital Pulse Advantage over Standard MIG

Conventional short-circuit MIG produces excessive spatter and inconsistent penetration on aluminum and stainless steel. The OTC DP400 delivers pulsed spray transfer—firing one molten metal droplet per electrical pulse—delivering TIG-like bead appearance at high MIG deposition rates.

Structural Aluminum Welding

Equipped with push-pull torches and pulse wave shaping, the DP400 prevents burn-through on thin 5052 aluminum while achieving full fusion on thick 6061 extruded frame joints without cold-lap porosity.

Direct-to-Powder-Coat Cleanliness

Because digital pulse produces zero spatter beads, welded frames transition straight into our automated conveyor wash and powder coating line without tedious chisel de-spattering or manual flap disc grinding.
