“LOW SPATTER” PROCESS WB 500L
PRINCIPLE OF LOW SPATTER
In short arc welding where short-circuiting
and arc are repeated, most of spatter is generated when short-circuit is caused and immediately before arc generation. In the latter timing which is immediately before arc
generation, a phenomenon called [Squeeze]
shown in the below figure occurs on the
wire. Detecting this [Squeeze] and rapidly
decreasing current at the exact moment
prevent molten metal being blown off by arc
force and enable significant suppression of
generation of spatter. For this purpose, it is
important to accurately detect [Squeeze].

WAVE PULSE FOR STAINLESS
LOWERS RISK OF POROSITY!
WAVE PULSE has a profound effect on reducing porosity (blowholes) due to the degassing
effect created by agitating the weld puddle at various low frequencies.

WAVE PULSE BENEFITS FOR STAINLESS
• Eliminate the need for expensive, hard to get Helium
gas mixtures
• Individual Pulse waveforms for Austenitic and Ferritic
stainless
• Provides smooth transfer of highly viscous stainless
steel welding wire to minimize spatter
• Achieve a TIG-like bead appearance with travel speed

SYNCHRO MIG WITH AC SERVO TORCH
Synchro MIG - This innovative function coordinates the
welding torch placement with the current.This feature is
ideal for welding different thicknesses together.With the
OTC Synchro MIG the heat intensity changes with thinner materials.The result is a top-quality, more attractive
weld. OTC’s system makes sure the heat input matches
the material.
TIG WELDING DA300P
DA-300P: WELDING MACHINE FOR THE AC/DC HYBRID PULSE TIG WELDING
The DA300P takes advantage of both AC and DC welding modes, which allow for extremely precise control of heat, weld penetration and bead shape.The DA-300P adds full digital control to these
processes, which in turn allow for a tighter degree of control than ever before.
COLD TANDEM
LOW HEAT INPUT WELDING SYSTEM
Cold tandem GMA welding that achieves low distortion Cold wire is added from the backside of the welding pool where arc heat is generated on preceding wire. This can remove the
excess heat from the welding pool for minimizing the heat distortion.
