The Decastar 150e features multi-step voltage switches rather than an infinite voltage dial. Finding the right balance between voltage (heat) and wire feed speed dictates your weld quality.

Let the machine rest with the fan running for 15 minutes to cool down. Wire speed too fast or voltage too low. Decrease wire speed or increase voltage setting. decastar 150e manual
