Pulse Welding

Pulsed MIG Welding is a process where the Power Source switches between a high and low current extremely fast. The advantage is a smooth spatter free weld with reduced overall heat input.

Welding Processes

The APT Forge Pulse Series redefines versatility by putting elite-level arc control at your fingertips. Whether you are navigating intricate positions, tackling heat-sensitive alloys, or executing high-speed industrial production, our specialised pulsing modes adapt dynamically to your workflow. Experience reduced spatter, minimised distortion, and a flawless finish across all materials.

POSITION

Combining a high-energy pulse phase with our specialised APT Cold technology, this process gives you complete control over the weld pool when fighting gravity. Perfect for vertical-up or overhead joints, it ensures excellent penetration while preventing the puddle from sagging.

Pulse

Our standard pulse mode delivers a highly stable, uniform arc that transfers a single droplet of metal per pulse. This eliminates spatter entirely, drastically reduces post-weld clean-up time, and offers incredible aesthetics on aluminum and stainless steel.

Duo Pulse

By alternating between two distinct energy levels, Duo Pulse creates a beautifully consistent, "stacked-dime" weld bead profile automatically. It provides exceptional thermal management, making it the ultimate choice for thin-gauge materials where appearance and heat control are critical.

Twin

Designed for maximum productivity, the Twin process seamlessly transitions between two separate operating parameters. This allows for rapid filling of large joints and high-speed travel without sacrificing arc stability or weld integrity.

APT Processes

Beneath the rugged exterior of the Forge Pulse Series lies our proprietary Advanced Power Technology suite. These specialised software algorithms modify the arc characteristics in real-time, solving the most common challenges faced by industrial fabricators—from deep groove penetration to open-root gaps.

APT Stabi

The APT Stabi process automatically compensates for changes in your torch distance (stick-out). Even if your hand moves, the machine dynamically adjusts the wire feed speed and current to guarantee a uniform depth of penetration throughout the entire weld.

APT Deep

Engineered for heavy-duty structural steelwork, APT Deep delivers a highly concentrated, forceful arc that penetrates deeply into the root. This allows for reduced bevel angles, less joint preparation, and significantly lower wire consumption on thick plates.

APT Cold

By minimising the thermal energy transferred to the workpiece, APT Cold reduces the risk of burn-through and material distortion. It is the ideal solution for ultra-thin sheet metal, gap bridging, and delicate automotive or aerospace fabrications.

APT Root

Say goodbye to backing gas and backing strips. APT Root is specifically tuned to create a perfectly fused, stable root pass on open pipes and plates. It bridges wide gaps with ease, offering a smooth, uniform root bead that passes stringent X-ray testing.

APT FP4 Wire Feeder

Fitted to the FP 400 and FP 500 Machines, the APT FP4 Wire Feeder Unit is a heavy-duty, separate wire feeding powerhouse, engineered for demanding industrial fabrication environments. Featuring a robust 4-roll wire drive assembly that ensures positive, slip-free feeding and perfect consistency even when utilising extended interconnecting cable packages. Optimised for advanced digital synchronisation, effortlessly communicating with the main power source to manage the ultra-high-speed 25,000 pulses-per-second wire control loop, facilitating advanced processes like Deep, Root, and Twin-Pulse with flawless arc stability.

APT Water Cooler Unit

High-Performance, modular cooling system engineered specifically as an option for the Forge Pulse FP 353, FP 400 and FP 500 power source models. Designed to handle the extreme thermal demands of high-amperage spray transfer and prolonged pulse welding, the unit delivers consistent torch cooling to protect consumables and maintain arc stability during heavy-duty production cycles.
For maximum efficiency, rather than running continuously at full capacity, the power source actively monitors internal temperatures and torch usage to cycle the water cooler's pump and fan only when required.
