Hi, I'm new to TIG welding and have just joined this forum having bought a Sherman 210.
I've been trying various settings to try and understand the effect they all have. The first thing that had me puzzled was that when I plug in the foot pedal the amps display just shows 10/11 amps. I now realise having read a Jasic manual and watched the Sherman video that it is necessary to operate the foot pedal to see the maximum amps. This will be like this, I assume, as it will also take into account the setting of the control on the pedal. But from the videos I have seen not all welders appear to be like this.
The part that really confuses me is the down slope time. The range is from 10 to 25 secs but having done some tests it appears that 25 secs is only possible with 200 amps welding current and 10 amps end current. It appears the slope is fixed at 7.6 amps per second. So if the welding current is set to to 100 amps & down slope to 10 amps the max down slope time is 12 secs and similarly for lower welding currents or higher ending currents. At 30A welding and 10A end current it would be less than 3 seconds.
This should not be a problem as I'll probably usually use the foot pedal but I wonder if others welders are the same? Any comments on this or this welder generally would be appreciated.
