TrueAutoMode automatically detects which tools (electrodes and arms) are in use and makes any necessary adjustments as it welds. This saves considerable time over other “automatic” welders that require technicians to stop and program the welder every time they change tips. TrueAutoMode measures weld resistance roughly 1,000 times per second and automatically adjusts current level, weld time and clamp pressure as needed. At the end of a job, it can print out a report that includes parameters of every weld for easy documentation
