China TIG cut MMA welder
Product Description SPECIALIST FEATURE • Pulse control:
Built in pulsing functions help minimize heat input on thin materials, and provide for a faster freezing weld puddle for uphill welding on curved surfaces such as process piping. The TIG pulse also helps moderate filler metal deposition for consistent bead appearance.
• High-frequency TIG starting:
Makes it easy to establish an arc under a variety of conditions. Enhances quality by minimizing the potential for weld
contamination created by tungsten inclusions in the weld.
• Refined arc ignition from 3A.
• Pilot Arc for superior arc performance and easy start.
• Rapid Arc Restrike: fast cutting through gaps, even expanded metal.
• Powerful with heavy duty: 50A @60%.
• Hot Start Function reliably ignites the electrode and melts perfectly to ensure the best quality even at the start of the seam.
• 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 TECHNICAL SPECIFICATIONS

Plasma cutter test performance
PULSED TIG CONTROLS The Pulsed TIG function switches the amperage from a high(peak) to a low(background) at a set rate(PPS). Pulsing can reduce heat input by lowering the average amperage, increasing control of the weld puddle, penetration and distortion. The following parameters can be adjusted for desired results:
Low-Speed Pulse | High-Speed Pulse |
| |
1 to 10 pulses per second(PPS) will produce a distinct ripple pattern in the weld bead. Can be used to time filler addition,reduce distortion and improve control. | 100 pulses per second(PPS) and higher helps to focus the arc for increased stability, penetration an d travel speed. Increased puddle agitation improves weld microstructure. |
HOT START Hot start function reliably ignites the electrode and melts perfectly to ensure the best quality even at the start of the seam. This solution makes lack of fusion and cold welds a thing of the past and significantly reduces weld reinforcement. Adjust the hot start current here and the time here.
Arcforce correction(welding characteristics) Arcforce is a setting that allows you to adjust the arc to soft smooth arc to a more aggressive digging arc. Setting high is to bump up amperage when you have a really tight arc so that you keep welding.
