Tungsten come in various sizes. What will happen when you attempt to weld with too high an amperage with too small a electrode diameter size? click all that apply.

• You will not be able to keep the point on your tungsten.

• You will struggle with arc start.

• Small diameter tungsten can not carry as much current.

• You will not be able to use pulsed current.
