I bought a welding inverter for welding thin sheet metal, when repairing a car body. It ignites and holds the arc well, thin metal does not burn through, and the wire is fed evenly, without jerks. When welding car body elements with an intermittent seam, the inverter almost does not heat up. If the seams need to be made continuous, or of great length, then after some time the automation turns off the welding machine and you need to wait for some time until it cools down.See full review
