Consumable electrode type pulse arc welding method

A consumable electrode type pulse arc welding method in which at least one of the welding current and the welding voltage provides output in a pulse manner, said method comprising the steps of:

• setting the welding current at an initial welding current setting value lower than that of a normal welding current setting value in a first step which is a first predetermined period of time from the start of welding;
• increasing the initial welding current setting value to the normal welding current setting value during a second step which is a second predetermined period of time after the first step has passed;
• and
• preventing a pulse output from the first step to a first point which is a predetermined setting value of the welding current in the second step prior to reaching the normal welding current setting value:,
• wherein from the first point till the end of the second step a change in the welding current per unit time of the rise and fall of the pulse output is less than a normal change in the welding current per unit time of the pulse output.
