Description

【０００１】
【発明の属する技術分野】
本発明は、電極と溶接母材（以下母材と言う。）との間にアークを発生させて溶接を行うアーク溶接条件入力装置に関する。
【０００２】
【従来の技術】
従来のアーク溶接条件入力装置では、種々の入力設定項目を選択するスイッチの設定と入力設定項目毎に設けられた可変抵抗器の調整により入力値を設定する。
【０００３】
図５に従来のアーク溶接入力装置の構成を示す。
【０００４】
図５において、２１は初期電流用可変抵抗器、２２は溶接電流用可変抵抗器、２３はクレータ電流用可変抵抗器、２４はパルス電流用可変抵抗器、２５はパルス周波数用可変抵抗器、２６は初期制御選択スイッチ、２７はクレータ制御選択スイッチ、２８はパルス制御選択スイッチ、２９は入力設定部である。
【０００５】
アーク溶接を行う際に、まず溶接条件を選定しなければならない。被溶接材料の材質、厚さ、継ぎ手形状等、溶接部が複雑になるに伴い溶接条件も複雑になり様々な制御、出力条件の設定が必要となる。
【０００６】
例えば、２００Ａの初期電流が必要であれば初期制御選択スイッチ２６を“有”に設定し、初期電流用可変抵抗器２１を概ね２００Ａの位置に調整する。
【０００７】
次に溶接電流用可変抵抗器２２で溶接電流を設定し、８０Ａのクレータ電流が必要であればクレータ制御選択スイッチ２７を“有”に設定し、クレータ電流用可変抵抗器２３を概ね８０Ａの位置に調整する。
【０００８】
溶接にパルス出力が必要であればパルス制御選択スイッチ２８を“有”に設定し、パルス電流用可変抵抗器２４でパルス電流を、パルス周波数用可変抵抗器２５でパルス周波数を設定する。
【０００９】
そして前記各可変抵抗器及び各選択スイッチの出力より入力条件を入力設定部２９で設定する。
【００１０】
また、上昇スロープ用可変抵抗器あるいは下降スロープ用可変抵抗器等が更に必要であったり、可変抵抗器及び選択スイッチの数は合計で２０ヶに達するものもある。
【００１１】
【発明が解決しようとする課題】
上記従来の構成では、可変抵抗器の調整及びスイッチ選択を行う際、その数が多いため設定抜けが発生する場合がある。
【００１２】
また、その数が多いので各々が接近した状態で配置されるため隣の可変抵抗器に接触し調整位置がずれることがある。
【００１３】
更に可変抵抗器を再調整するにも概ねの位置でしか調整できないので、必ずしも再現するとは限らない。
【００１４】
この場合、次の溶接を入力条件が適正であることの確認用としなければならない。
【００１５】
本発明は上記の課題を解決するもので、設定抜けが防止でき、また、確定状態の入力値はずれることはなく、入力数値を管理しておけば容易にそして正確に入力値の再調整を行うことができるアーク溶接条件入力装置を提供するものである。

【００２２】
【発明の実施の形態】

BACKGROUND OF THE INVENTION
The present invention relates to an arc welding condition input device for performing welding by generating an arc between an electrode and a welding base material (hereinafter referred to as a base material).
[0002]
[Prior art]
In a conventional arc welding condition input device, an input value is set by setting a switch for selecting various input setting items and adjusting a variable resistor provided for each input setting item.
[0003]
FIG. 5 shows the configuration of a conventional arc welding input device.
[0004]
In FIG. 5, 21 is a variable resistor for initial current, 22 is a variable resistor for welding current, 23 is a variable resistor for crater current, 24 is a variable resistor for pulse current, 25 is a variable resistor for pulse frequency, 26 Is an initial control selection switch, 27 is a crater control selection switch, 28 is a pulse control selection switch, and 29 is an input setting unit.
[0005]
When performing arc welding, the welding conditions must first be selected. As the welded part becomes complicated, such as the material, thickness, and joint shape of the material to be welded, the welding conditions also become complicated, and various control and output conditions need to be set.
[0006]
For example, if an initial current of 200 A is necessary, the initial control selection switch 26 is set to “present” and the initial current variable resistor 21 is adjusted to a position of approximately 200 A.
[0007]
Next, the welding current is set by the variable resistor for welding current 22, and if the crater current of 80A is necessary, the crater control selection switch 27 is set to “present”, and the variable resistor for crater current 23 is set at the position of about 80A. Adjust to.
[0008]
If pulse output is necessary for welding, the pulse control selection switch 28 is set to “present”, the pulse current variable resistor 24 sets the pulse current, and the pulse frequency variable resistor 25 sets the pulse frequency.
[0009]
Then, an input condition is set by the input setting unit 29 from the outputs of the variable resistors and the selection switches.
[0010]
Further, there are some cases where a variable resistor for rising slope or a variable resistor for falling slope is further required, or the total number of variable resistors and selection switches reaches 20.
[0011]
[Problems to be solved by the invention]
In the above-described conventional configuration, when adjusting the variable resistor and selecting the switch, there are cases in which a setting omission occurs due to the large number of the resistors.
[0012]
In addition, since the number is so large that they are arranged close to each other, the adjacent variable resistor may be touched and the adjustment position may be shifted.
[0013]
Furthermore, even if the variable resistor is readjusted, it can be adjusted only at an approximate position, so that it is not always reproduced.
[0014]
In this case, the next welding must be used to confirm that the input conditions are appropriate.
[0015]
The present invention solves the above-mentioned problems, can prevent setting omissions, and does not deviate from the input value in the definite state. If the input numerical value is managed, the input value is readjusted easily and accurately. An arc welding condition input device capable of performing the above is provided.
[0016]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a liquid crystal display, a counting display, an input value setting and display signal, and an input value adjustment state or an input value confirmation state is selected and controlled to adjust the input value.

In this state, the rotation amount of the push-in dial 4 is used as an item selection to select an item, and the previous determined input value of the selected item is displayed on the counting display 8. Next, when the detection signal for the push-in operation is input, the selected item is confirmed and the input value is increased or decreased according to the rotation amount of the push-type dial 4.
[0042]
What was demonstrated as an arc welding condition input device is applicable to a welding machine, a wire feeder, a remoteness controller, and a torch.
[0043]
【The invention's effect】
As described above, after the input value is adjusted, the input value is determined by pressing the push switch, and the items to be input with the next numerical value are displayed on the display unit, so that the set item can be prevented from being lost. Further, since the input value in the definite state cannot be changed, the adjustment is not shifted, and if the input numerical value is managed, the input value can be readjusted easily and accurately.
[0044]
Further, when the input value is confirmed, it is easy and accurate to recognize the input value adjustment state or the input value confirmation state by moving the input value display location from the counting display to the liquid crystal display.
