Kemppi Kempact 323A MIG/MAG Welding Machine

Overview

The Kemppi Kempact 323A is a compact MIG/MAG welding machine with an integrated wire feeder, belonging to Kemppi’s Kempact RA family. The 323 designation refers to its 320 A maximum output on a three-phase 400 V supply, and the A suffix denotes the Adaptive control panel, which adds automatic power regulation by plate thickness and weld profile, a memory for frequently used settings, crater fill and adjustable post gas. Kemppi describes the Kempact RA family as setting new standards for the compact MIG/MAG class, with a design that is easy to move around the workshop on its own chassis.

Seven Star LLC supplies the Kemppi Kempact 323A to fabrication workshops, maintenance departments and training centres in Oman and the GCC, with engineering support in Muscat. We can supply the machine with suitable feed rolls, contact tips and liners for steel, stainless or aluminium wire, and with solid and cored filler wires from our consumables range.

Operating Principle

As general background, in MIG/MAG welding a continuous wire electrode is pushed through the gun and melted in an arc that is protected by shielding gas. The power source controls arc voltage while the wire feed speed sets current. In the Kemppi Kempact 323A, the gun’s Euro connector is connected to the positive pole on delivery; Kemppi notes that the terminals inside the wire feed case can be swapped when running a filler wire specified for reverse polarity. An autostop safety function stops wire feed and gas and removes voltage from the wire if the trigger is held for more than 30 seconds without the arc igniting.

On the Kemppi Kempact 323A in Adaptive mode with AUTOMATIC selected, the welder chooses the filler material type (Fe, brazing, FCAW or MCAW), the wire diameter and the shielding gas, then sets the power with one knob; the second knob trims arc length. A dynamics control from minus 9 to plus 9 adjusts the rate of current rise during short circuits: negative values give a hotter, more fluid weld, and positive values a colder arc. MANUAL mode remains available for independent voltage and wire speed control.

Engineering Design of the Kemppi Kempact 323A

The Kemppi Kempact 323A stands on a wheeled chassis measuring 623 by 579 by 1070 mm and weighs 44 kg without gun and cables. The Kemppi Kempact 323A takes wire spools up to 300 mm in diameter and 20 kg, so it can run long between spool changes. The manual names the GasMate chassis as a way to secure the gas cylinder upright, and the machine also features Brights cabinet lighting. A large orange backlit LCD shows parameters clearly, and a polycarbonate lens protects the display.

Electrically, the Kemppi Kempact 323A is designed for 3-phase 400 V plus or minus 15 percent at 50/60 Hz, with a type C 10 A fuse and a 5 m H07RN-F 4G1.5 supply cable that the user fits with a suitable plug. Rated power is 12 kVA at 35 percent duty cycle and 320 A. The casing is rated IP23S, EMC class A and temperature class F. Kemppi lists conformity with IEC 60974-1, -5 and -10, and the operating range is minus 20 to plus 40 degrees Celsius.

Key Features

The following points summarise the Kemppi Kempact 323A from the operating manual:

• It delivers a welding range of 20 A at 10 V up to 320 A at 32.5 V, with 320 A available at 35% duty cycle.
• Wire feed speed is adjustable from 1.0 to 20.0 m/min and voltage from 8.0 to 32.5 V, both steplessly.
• The machine welds Fe solid and cored wires from 0.8 to 1.2 mm, stainless 0.8 to 1.2 mm, aluminium 1.0 to 1.2 mm and brazing wire 0.8 to 1.0 mm.
• The Adaptive panel offers automatic power regulation by plate thickness and weld shape, plus a memory function.
• Crater fill and post gas from 0.1 to 3.0 seconds are selectable on the Adaptive panel.
• A spot and cycle arc timer sets spot times from 0.1 to 9.9 seconds and pause times up to 3 seconds.
• A 2T/4T trigger mode, WireLine maintenance alert and overheating indicator support day-to-day use.
• The HOT SPOT function provides localised spot heating for straightening and stress relieving of panels.

Industrial Applications

The Kemppi Kempact 323A is a good fit for general fabrication shops in Muscat, Sohar and Salalah that build frames, skids, supports, gratings and light structural assemblies in carbon steel, as well as stainless and aluminium items with the correct liner and rolls. Workshops serving the oil and gas, utilities and construction sectors choose the Kemppi Kempact 323A because they value its integrated design, which avoids a separate feeder and interconnection cable, and its large spool capacity for longer production runs.

The Adaptive controls also make the Kemppi Kempact 323A useful in vocational training centres and maintenance departments, where welders of varying experience need repeatable settings that can be stored in memory. Seven Star LLC supplies the machine with MIG wire, flux-cored wire and spare parts, and our Muscat engineers help with commissioning advice such as plug fitting and feed roll selection.
