Mag­num Welders’ Mini Dig­i­tal TIG 200E, which at 8kg is Aus­tralia’s small­est dig­i­tal TIG AC/DC welder, is at­tract­ing so much in­ter­est that it was a fi­nal­ist in the re­cent Ma­chine of the Year Awards at Henty Ma­chin­ery Field Days in NSW.

In de­vel­op­ing the AC/DC Pulse TIG/Arc/Alu­minium 200amp welder, Mag­num Welders own­ers Graeme and He­len McLaren man­aged to take 22kg off the 30kg weight of the pre­vi­ous equiv­a­lent welder.

He­len says they achieved its por­ta­ble size, light weight and low power con­sump­tion by us­ing the lat­est Pulse Width Mod­u­la­tion and IGBT In­verter tech­nol­ogy to re­place heavy trans­form­ers.

“The pa­ram­e­ters on the front panel can all be ad­justed con­tin­u­ously via one dial, such as start cur­rent, crater arc cur­rent, weld­ing cur­rent, base cur­rent, duty ra­tion and up­s­lope/downs­lope time,” she says.

“There is also pre/post gas, pulse fre­quency, AC fre­quency, hot start, arc force and arc length.

“When weld­ing, it takes high fre­quency and high volt­age for arc ig­nit­ing to en­sure the suc­cess ra­tio of ig­nit­ing arc.’’

Its fea­tures in­clude: 2T/4T ex­change func­tion; DC func­tion for mild steel, stain­less steel, cop­per, chrome moly and non-fer­rous metal ma­te­ri­als; AC func­tion for weld­ing alu­minium and alu­minium al­loy ma­te­ri­als; and a dig­i­tal LCD dis­play to show cur­rent out­put.

The Mini Dig­i­tal TIG 200E comes with a 3m elec­trode holder lead, 3m earth clamp lead, and 4m gas hose. It costs $1750 plus sig­na­ture-on-de­liv­ery postage and han­dling, and comes with a two-year war­ranty.
