Welding device having a selector to designate welding conditions

A welding device comprising:

• a welding torch including:
• a welding tip having a feeder for providing a welding wire;
• and
• an insulating member disposed nearer to a work-piece to be welded than the feeder and having a through hole in order to insert the welding wire;
• a memory that stores a plurality of welding conditions including a welding current waveform controlling parameter including a current slope during a short-circuit period associated with a length of the insulating member along the through hole;
• a power supply that supplies electric power between the feeder and the work-piece;
• an input section that receives an input of a set value of the length of the insulating member along the through hole;
• a selector that selects one of the plurality of welding conditions based on the set value of the length of the insulating member along the through hole;
• and
• a controller in communication with the selector, the controller operable to control the power supply based on the welding condition selected by the selector.
