- Code: 285000 power source with earth clamp
- MMA welding in direct current DC
- It allows to weld with many types of electrodes and materials: rutile, basic, stainless steel, cast iron, etc.
- HOT START adjustable. For easy electrode striking. Useful especially for "diffi cult-to-start" electrodes.
- ARC FORCE adjustable. Enables to control the welding penetration and improve the arc stability.
- ANTI – STICKING. No electrode sticking.
- AC DC TIG welding
- DC: direct current to weld steel, stainless steel, titanium, copper, bronze, nickel.
- AC: alternating current to weld aluminium magnesium and aluminium silicium.
- AC EASY: FREQUENCY (Hz) and BALANCE (%) are automatically adjusted depending on the welding parameters set.
- PULSE: The welding current is pulsed. Main current "I (Amp)" and base current "(%) I" alternate. Particularly suitable for welding thin thickness, where minimum heating of the piece is necessary, and suitable for welding in all positions.
- EASY PULSE: Pulse frequency, "PULSE (Hz)", and base current "(%) I" are adjusted automatically depending on the welding parameters selected.
- BI-LEVEL: two different current settings are selectable during welding process. Extremely useful for complex welding, welding over variable thicknesses or for welding on position.
- TIG HF LIFT striking: TIG welding with high frequency arc striking TIG welding with LIFT ARC striking.
- 2T (manual): press and keep the torch trigger pressed to weld, the weld will stop as soon as the button is released.
- 4T (automatic): press and release the torch trigger to start welding, the weld will last until the trigger is pressed and released once again.
- SPOT: TIG welding fi nishes automatically once the pre-set time has elapsed.
- Program saving. The mode settings and the parameters set can be saved to the machine for future use. There are 9
- Tig welding: adjustable parameters
a) Ø mm: Select the diameter of the tungsten electrode. Based on the diameter selected, the machine determines the welding current interval that can be used without damaging the electrode.
b) PREGAS: Pre-gas time adjustment.
c) SLOPE-UP: Adjustment of time at which the welding current is brought from the initial value (arc start) to the main value "I (Amp)".
d) I (Amp): Main welding current adjustment.
e) (%) I: In the "PULSE" and "BILEVEL 4T" modes, it adjusts the base welding current, expressed as a percentage of the main welding current.
f) SLOPE-DOWN: Time at which, once the torch button is released, the welding current is brought from the main value to the final value (end of welding).
g) POSTGAS: Post-gas time adjustment.
h) PULSE (Hz): In the "TIG PULSE" mode, it varies the pulse frequency.
i) BALANCE (%): In the "TIG AC" welding mode at alternating current, it modifies the ratio between the duration of the positive and the negative half waves. Low "balance" values allow for enhanced arc penetration and little electrode wear and tear. High "balance" values allow for better cleaning of the workpiece but increased electrode wear and tear.
l) FREQUENCY (Hz): In the "TIG AC" welding mode at alternating current, it varies the welding current frequency. Low values allow for a better distributed arc. High values allow for a more concentrated arc.
m) T (SPOT): In the "SPOT" mode it varies the duration of the welding point.
