I use it at work. Easy to grip and easy to enter power. But, is the tip slightly weak? Because it became useless for a year's strength, I repeated. Satisfying when considering the amount of money.
It seemed that the joining of the head and the shaft was bad, so I started using it and it started idling soon. Since it was a work at the outside site, there was no replacement tool, and it happened to have another welder brought the welding machine, so it was no use stopping the work on the spot without stopping welding the head and the shaft. It is very troubling if there is such a thing.
