Semi-automatic Arc Welding Machine Equipped with the “Full Digital” Series

Features and Effects of Various Pulse Controls

Overview

Better welding results can be obtained by selecting and using the appropriate functions.

This page introduces the pulse function equipped on some Panasonic full digital welding machine models by control system.

GT Pulse Control

It combines the advantages of three conventional pulse control methods (hybrid, soft, and hard) into one and adds arc tracking characteristics to create an optimal arc. Effective in stabilizing hand shaking, undercutting suppression, and reducing spatter.


GTパルス制御1

Current/voltage: 200 A/25.2 V  Speed: 50 cm/min  Base metal: Mild steel  Thickness: 4.5 mm (black iron)
Joint: Horizontal fillet weld  Wire: Mild solid steel  Diameter: 1.2  Shield gas: Ar 80% + CO2 20%


GPパルス制御2

Current/voltage: 160 A/20.2 V  Speed: 50 cm/min  Base metal: Stainless steel (SUS304)  Thickness: 3 mm
Joint: Horizontal fillet weld  Wire: SUS308  Diameter: 1.2  Shield gas: Ar 98% + O2 2%

VP Pulse Control

Further evolution of GT pulse control. The arc length is controlled at a constant level even when the electrode extension changes, thus realizing high-precision pulse welding without concern for shaking.

HD-Pulse Welding Method

This method accomplishes low spatter in the high electric range and ideal penetration.
It enables high-quality welding with gapped workpieces and is effective in suppressing undercuts and preventing arc blow.

VH Pulse Control

The problem with high-current welding is the rotating transition, which causes the tips to melt and chain together, and rotate under the influence of electromagnetic forces. This makes the arc unstable and causes more spatter.
Pulse control on the YD-700VH1 provides stable droplet transfer with spray transfer, resulting in a stable arc and reduced spatter.
