When set on “Auto” both phaser models switch to maximum impulse frequency (welds per second) depending on the chosen energy parameters. This frequency option allows very fast welding where needed. The option “fixed-2sec.” provides one weld only every two seconds. This setting is very helpful on complicated and advanced cases where initially just one shot is indicated.  With the optional foot pedal the impulse is not triggered by touching the workpiece with the electrode, but only by pushing the pedal.

The result: the new phasers offer the adequate speed for every welding job.
