The Kemppi Kempact 2530 is a compact inverter MIG/MAG power source, in which the power source and the feeder sit in one housing. The welding current reaches 250 A at a 40% duty cycle and 160 A in continuous work at 100%, with a three phase supply of 400 V. The whole machine weighs 22 kg, so you carry it with no trolley and no crane.
What this machine is for
This is equipment for workshop work, assembly work and light production of steel structures. A current of 250 A covers the usual thicknesses of sheet and section met in metal work and body work, and on longer beads you count on 160 A at a 100% duty cycle. The compact build joins the power source and the wire feeder in one housing, so interconnection cables fall away and the station takes up less room.
A weight of 22 kg at a current of 250 A is the main plus of this model. You carry the machine up the stairs, put it into a van and set it on a scaffold, where a heavy transformer MIG welder would be a nuisance. Assembly and service crews take such a unit to a site, and in the workshop it serves as a second, mobile station that you set down where the part happens to lie.
The maker aimed this model at body and metal workshops, at assembly crews working in the field and at height, at the production of light steel and aluminium structures and at maintenance and rebuilding work in industrial plants. After you change the rollers to a groove for soft wire and the liner to a teflon one, the machine also feeds aluminium wires, and for steel you go back to rollers with a V groove.
Features and equipment
- Compact build: the power source and the feeder in one housing, with no external connecting cables, and a housing that shields the electronics from workshop dust.
- Weight of 22 kg with a handle shaped for carrying: you move the machine between stations with no lifting gear.
- Four roll DuraTorque feed mechanism: four drive rollers guide the wire without slip, and the pressure adjustment lets you work also with soft aluminium wire without crushing it.
- Panel with two knobs: you set the welding voltage and the wire feed speed, with no walking through a menu, in welding gloves.
- Inverter technology: smaller size and a fast reaction to changes in the arc across the whole current range.
- Electronic arc stabilisation: the circuit watches the arc in real time, limits spatter and gives repeatable fusion also under CO2.
- Wire spool 200 mm with a weight of 5 kg: a standard size that fits in the housing.
- Work from a generator of suitable power and voltage stability.
Inverter technology gives two things here at once: a smaller size than in a transformer machine and faster control of the current characteristic. You see that when you weld materials with different heat removal, where the arc has to keep up with the change of conditions in the pool. Electronic arc control limits spatter, so after welding under CO2 there is less grinding left.

What to watch out for
The supply is three phase 400 V, so for work in the field you need a power socket or a generator of suitable power and voltage stability. The torch is gas cooled, you add no cooler, but on long welds at high current it is the torch that is the bottleneck: in continuous work count on 160 A. A 5 kg spool means a more frequent change of wire on longer series, so in continuous production add the stops for changeover.
For aluminium prepare rollers with a U groove and a teflon liner, because the standard equipment is made for steel wire. Before you buy, settle with us which torch and earth cable belong to this piece and which set of rollers is fitted in the feeder. Check also the state of the liner and of the contact tips in the torch, because these are wear parts, and in a compact build they cause most of the trouble with wire feeding.
