TPmc remote
control unit
This workplace remote control unit is intended for use in particular with manual electrode
and TIG welding.

(34) Welding current dial
- for continuous adjustment of the welding current
(35) Arc force control dial
- influences the short circuit amperage at the moment of drop transfer (from
electrode to workpiece)
At scale setting "0" there is no increase at all in the short circuit amperage at the
moment of drop transfer (soft arc).
Range of application: welding using rutile electrodes (fine globules), basic shea-
thed electrodes in the medium and upper amperage ranges
NOTE! When welded at low load, basic-sheathed electrodes tend to "GET
STUCK" on the workpiece.
At scale setting "10" there is a very considerable in-crease in amperage at
the moment of drop transfer (hard arc).
Range of application: Basic sheathed electrodes (coarse-globule), when these are
to be welded in the lower amperage range (vertical-up seams, edge hardfacing
welds, root welding etc.)
Important! When the setting on the arc force control dial is adjusted upwards, the
following may be observed when rutile, basic-sheathed or special electrodes are
being used:
- easy ignition
- reduction in welding misfires
- less electrode burn-on
- good root penetration
- occasionally an increase in spattering
- when welding thin sheet metal the danger of "burning through" increases
