Abstract
Method and device for igniting and/or re-igniting a welding arc (SLB) between a wire end of a consumable welding wire electrode (SDE) and a workpiece (W), comprising the steps of: determining (S1) a distance (S) or time duration required by the wire end of the consumable welding wire electrode, SDE, until contact or short-circuit with a surface of the workpiece (W); and igniting (S2) the welding arc (SLB) with an ignition energy, EZ, which is set in dependence upon the determined distance (S) or time duration.
Claims13
A method for igniting and/or re-igniting a welding arc between a wire end of a consumable welding wire electrode and a workpiece after an event comprising the steps of:
- determining a distance or time duration required by the free wire end of the consumable welding wire electrode until contact or short-circuit with a surface of the workpiece or until ignition of the welding arc;
- and
- igniting the welding arc with an ignition energy which is set in dependence upon the determined distance or time duration.
An ignition device for igniting and/or re-igniting a welding arc between a wire end of a consumable welding wire electrode and a workpiece, comprising:
- a determination unit which is suitable for determining a distance or time duration required by the free wire end of the consumable welding wire electrode until contact or short-circuit with a surface of the workpiece or until ignition of the welding arc;
- and comprising
- a setting unit which is suitable for setting an ignition energy for igniting and/or re-igniting the welding arc in dependence upon the distance or time duration.
An arc welding apparatus comprising an ignition device for igniting and/or re-igniting a welding arc between a wire end of a consumable welding wire electrode and a workpiece and comprising a welding torch,
- said ignition device comprising:
- a determination unit which is suitable for determining a distance or time duration required by the free wire end of the consumable welding wire electrode until contact of short-circuit with a surface of the workpiece or until ignition of the welding arc;
- and comprising
- a settling unit which is suitable for setting an ignition energy for igniting and/or re-igniting the welding arc in dependence upon the distance or time duration.
