KEY GREE TIG-250P 250 Amp AC/DC Aluminum Tig Welder with Pulse Digital Inver...

Description

The TIG250P AC/DC TIG Welder with Pulse features the versatility to suit the needs of hobbyists and professional welders, especially for welding aluminum with AC TIG and Pulsed AC TIG Modes.
This is a 250A welder that requires accessories like electrode positioning system, arc voltage control, oscillator, seam tracking device, feed wire mechanism, etc. This welder is used in both semi-automatic and automatic versions of welding. The materials used in the tungsten rod are argon and filler wire. Argon is used as the shielding gas.
It produces high performance with an array of pulse features, includes 250 amps of alternating current( a start AMP 5 to 250) or direct current TIG welding along with stick function, comes with WP-26 heavy-duty TIG torch.
Digital indicator
Display amperage for viewing of the actual and preset values for greater accuracy and repeatability in your welding procedure.
Pulse frequency control,pulse width/frequency (0.5Hz-200Hz)
Pre-flow and post-flow time control (0.1s-10s)
Up/down-slope time control (0.1s-15s), fine control of current reversal
Crater/start/pulse current control(5A-250A for TIG, 10A-160A for MMA)
Self-adjustable arc force current: for good operation while under long-distance welding.
Multiple welding processes
Equipped with AC Square Wave TIG, AC pulse TIG, DC TIG, DC Pulse TIG, DC Flux-coated Electrodes MMA, and argon arc spot welding (DC, pulse or AC).
HF arc starts built-in pressurized arc ignition circuit; also applicable to TIG no-HF arc ignition.
Squarewave is the best option to improve your weld quality and make aluminum welding easier.
Capable of 2T/4T/spot welding t
MMA hot start, easy arc start, stable current, minimum spatter, no sticking, good shaping
Perfect auto memory
Fan intelligent temperature control: prolong the fan’s lifespan.
Autosaving of welding parameters while power off
Auto recovery of last time’s welding parameters.
250Amp AC/DC TIG Aluminum Welder
The digital welding torch is compatible with this welder.
IGBT inverter technology
IGBT inverter, smaller size and lighter weight, and higher reliability.
Great reduction in copper and core loss greatly enhances the welding efficiency and saves energy.
Switching frequency is beyond audio frequency, which almost eliminates noise pollution.
Optional Functions
VRD: to ensure the operator’s safety while in idle mode
Anti-sticking: lower the machine’s working intensity
