ALUMTIG 200
FUNCTION
PARAMETERS PURPOSE
13. 2T/4T Selection
N/A
To operate with the torch switch, select 2T or 4T (2T Double
ended arrow 4T separate arrows). For 2T operation, simply press
and hold the switch. The panel program will cycle automatically.
When the switch is released, the arc will downslope and
terminate with post gas flow. When in 4T mode, the switch is
pressed, and held to start the pre‑flow and the start amps part
of the cycle. When released, upslope be‑gins and continues until
the amps are raised to the preset welding amps. When pressed
and held again, downslope starts and ramps down to the end
amp stage (crater current). When released, the arc terminates,
and post flow begins. If desired, before the downslope finishes,
the switch may be tapped again to start the up slope again.
14. HF or Lift TIG
Selection
N/A
The Process selector offers the choice of Lift Tig (for DC only)
which requires contact with the metal to initiate the arc and
High Frequency Start which allows non contact starting of the
arc (for AC and DC). (HF is selected when symbol is not striked
out) The lift start function on the ALUMTIG 200 provides a cold
electrode for safety, and prevents accidental starts. This requires
that the pedal or torch switch must be used to energise the arc.
HF refers to the start type only. The inverter design of the welder
eliminates the need for a constant HF overlay in AC.
15. Welding Current
N/A
This displays the Amps in real time while welding and will hold
after weld is complete.
16. AC or DC Selection
N/A
The unit features AC/DC operation. This machine uses advanced
square wave for AC that has excellent wet in, and arc stability.
