Overview

The UNI-MIG250 is a new inverter-based portable Mig welding machine with added MMA and Tig function. The Mig

function allows you to weld with both Gas Shielded and Gas-less wire applications. Easy step less adjustment of voltage and

wire feed make for easy setting of welding parameters giving excellent, professional welding results. Wire inch gives easy

feeding of the wire during set up without gas wastage and the Burn Back adjustment leaves the wire stick out ready for the next

weld. MMA welding capability delivers easy electrode welding with high quality results, including cast Iron, stainless and low

hydrogen. Connection of the 17V tig torch provides quality DC Tig with Lift Arc start for welding of steel, stainless steel and

copper. An additional feature is the Spoolgun ready function that allows the simple connection of the SPG200 Spoolgun for the

use of thin or softer wires that don’t have the column strength to feed through standard mig torches, such as aluminium wire.

This an industrial machine that is lightweight and portable, an optional trolley with drawer and cylinder rack provides off the

ﬂoor operation and better manoeuvrability around the workshop. Being 240v single phase gives great portability. Ideal for

general engineers, maintenance workshop, rural workshop, panel beaters, home workshop. Designed and built to our

speciﬁcation. Certiﬁed to - AS/NZ60974.1
