$3299.00 $2499


TITAN 221iMSTA is a modern 220amp – 4in1 compact inverter welder with clear easy-to-follow Large 5” Colour LCD screen display, AC/DC, High-Frequency TIG, Synergic MIG and MMA functionality all in one machine.

The 221iMSTA offers simple step-by-step digital LCD control of parameters providing easy-to-use professional control.
Manufactured using the latest IGBT technology with energy-saving power-factor correction standard.
It has an easy-to-use LCD menu including a Synergic MIG option; allowing the operator to simply select plate thickness and weld.
The 221iMSTA comes with pre-gas, slope-up, peak and base current settings along with AC/DC pulse width, frequency, wave balance, down-slope and post-gas flow, giving the operator complete arc control. 2T or 4T trigger function setting allows easy control of the welding process from start to finish.
It is equipped with an integrated 2 Roll GEARED METAL Wire feed unit and capable of accepting both 1kg & 5kg spools.

PFC technology means the TITAN 221iMSTA is extremely power efficient, delivering higher duty cycle for longer cuts and higher productivity, even on heavier section material.
PFC allows this welder to be used on long extension leads. (up to 100m)
A great choice for operation on generator power, where required.

Ideal for onsite repairs and maintenance, medium industrial workshops, car panel repairs or serious welders that want a single phase inverter they can plug in and use around their own home workshop.

Built to our specification and manufactured in compliance to ISO/IEC/AS 60974.1
