Micro Engineering Works

Digital display of welding current adjustment. Direct and convenient.
Having the function of auto-protection against over-voltage and over-current
Based on the inverter technology. with the function of TIG and MMA.
Easy to start the arc : with stable welding current : reacting fast : with no noise:
little spatter and little magnetic bias to make welding seam beautiful
Reliable and energy-saving. Convenient to take around with small dimension and weight.
Very suitable for the welding of stainless steel, carbon steel, copper, etc.
