Protig 200Di/250Di/315Di/400CT/500CT Welding Machine Power Source Welder powerful.excellent DC pulse TIG

TOP Features:

Pulse control:Built in pulsing functions help minimize heat input on thin materials, and provide for a faster freezing weld puddle for uphillwelding on curved surfaces such as process piping. The TIG pulse also helps moderate ?ller metal deposition for consistentbead appearance.

High-frequency TIG starting:Makes it easy to establish an arc under a variety of conditions. Enhances quality by minimizing the potential for weldcontamination created by tungsten inclusions in the weld.

Refined arc ignition from 3A.

Hot Start Function reliably ignites the electrode and melts perfectly to ensure the best quality even at the start of theseam.

Arc Force makes it easier to weld large-drop melting electrode types at low current strengths with a short arc in particular.

Fast Spot Arc system simply controls the spot arc parameter and offers a stable arc.

4T Trigger Hold allows to hold the present current by user until press the trigger again.

Fast, precise, clean arc ignition and arc ending.

10 channels memory capacity

PULSED TIG CONTROLS

The Pulsed TIG function switches the amperage from ahigh(peak) to a low(background) at a set rate(PPS). Pulsingcan reduce heat input by lowering the average amperage,increasing control of the weld puddle, penetration anddistortion. The following parameters can be adjusted fordesired results:

HOT START

Hot Start adaptive control provides positive arc start withoutsticking.

Arcforce correction(welding characteristics)

Arcforce is a setting that allows you to adjust the arc to softsmooth arc to a more aggressive digging arc. Setting high is tobump up amperage when you have a really tight arc so thatyou keep welding.
