Turn on the heat with Hotspot

Perfect for vehicle repair and thin sheet fabrication environments, the HotSpot function with four different heat settings makes metal shrinking and component heating simple and convenient. Fit the carbon electrode set to the FE welding torch and activate HotSpot on the control panel. Once the carbon electrode touches the workpiece, it forms an electrical circuit that gently heats the metal’s surface. HotSpot can also heat and help loosen corroded nuts, bolts, and other metal components.


Floor level design

GasMate chassis design makes gas cylinder collection, storage and movement easy. Gas cylinders are floor-level loaded and secured with a strong fabric webbing system.


Kempact RA gets the job done

Kempact RA is ideal for a variety of MIG/MAG welding applications. From vehicle repair to light- and medium-fabrication workshops, Kempact RA delivers reliable results.


Special features in Kempact Adaptive (A) models

Adaptive (A) models offer all the standard features provided in Regular panels, like Gas Type Selection, 2T/4T Gun Latching Mode, Spot/Cycle Arc Timer and HotSpot Function. Adaptive panels include plate thickness control, filler material selection, and four memory channels, plus an adaptive mode setup for your convenience.


415v MIG Welders FAQs

Straight answers to the questions people ask most when choosing a three-phase MIG welder for workshop and production use.

Who needs a three-phase MIG welder?icon-minus-redicon-plus-red

Three-phase machines suit fabrication shops, production lines, engineering workshops and anyone welding thicker material or for long periods. A three-phase supply carries more power for a given current per phase, so these machines can give higher output with a steadier load on the supply.

If you only have a single-phase supply, you are limited to single-phase machines.

What is the difference between 400v and 415v on these machines?icon-minus-redicon-plus-red

In practice, very little. Older documents and some machine labels refer to 415v, while the current nominal figure for a UK three-phase supply is usually given as 400v. Machines are normally designed to work within a tolerance either side of their rated input, but the allowed range depends on the maker and the model.

Check the data plate and the manual for the supply the machine accepts, compare that with the measured supply at your site, and ask a qualified electrician if you are unsure.

Do I need special wiring or a fuse rating to install one?icon-minus-redicon-plus-red

Yes, it needs a three-phase connection with the correct cable size and protection for the machine's input current, installed by a competent electrician. The manual states the recommended supply cable and fuse or breaker rating.

Do not connect a machine to a circuit that has not been checked for the load. Poor supply causes tripping, overheating and unreliable welding.

Air-cooled or water-cooled: which should I choose?icon-minus-redicon-plus-red

Air-cooled torches are simpler and need no extra equipment, and suit many general jobs. Water-cooled torches carry higher current for longer without overheating, so they suit heavy, continuous or production welding, but they need a cooler and a little more upkeep.

Choose according to the current and the duty cycle you will use.
