Question

what is adaptive hot start?

automatically increases output amperage at start of the weld
a form of hot start
amount of additional amperage supplied at start of arc based on amount of time electrode is in contact with workpiece
all of the above

Explanation:

Define standard Hot Start

Using the Hot Start Function knowledge point

• Hot Start automatically increases output amperage at the start of a weld to prevent electrode sticking.

Analyze Adaptive Hot Start

Adaptive Hot Start is a specialized form of the hot start function. It measures the contact time between the electrode and the workpiece to dynamically scale the additional amperage supplied.

Evaluate the options

• Option 1: "Automatically increases output amperage at start of the weld" is true for Adaptive Hot Start.
• Option 2: "A form of hot start" is true.
• Option 3: "Amount of additional amperage supplied at start of arc based on amount of time electrode is in contact with workpiece" is the specific definition of the "adaptive" mechanism.
• Since all individual statements are correct, "All of the above" is the correct choice.

Answer:

• (A) Automatically increases output amperage at start of the weld
• (B) A form of hot start
• (C) Amount of additional amperage supplied at start of arc based on amount of time electrode is in contact with workpiece
• (D) All of the above (Correct answer)
