Multiprocess Welder and Tig HF start

admin

Hi all,Does anyone know why all the Multiprocess Welders (GMAW, SMAW, GTAW, etc) does not have TIG with High Frequency Start? Thanks in advance for your comments Mauricio
Reply:TD does have one out,I have not used the machine but it is suppose to be a real nice machine.Ron
Reply:Probably because all the ones I'm thinking of are DC only machines. The ones I'm thinking of have lift arc rather than HF start..No government ever voluntarily reduces itself in size.

Reply:I would not want a hf start multi process machine.Thermal arc multi process machines are dc only and lift start tig. You can add a foot pedal to the 252i for variable amperage control.If you want to weld aluminum with these, you can add on a spool gun.JasonLincoln Idealarc 250 stick/tigThermal Dynamics Cutmaster 52Miller Bobcat 250Torchmate CNC tableThermal Arc Hefty 2Ironworkers Local 720
Reply:At Miller  and Lincoln web sites, I do not find any Multiprocess machine qith High Frequency Start, so, what do you think?It´s no possible to build a machine like this in only one box?Mauricio
Reply:There is no HF start on (DC) multiprocess power sources because they are complicated enough without having to generate AC weld power which is typically associated with HF.  If you want AC, buy a Dynasty, Syncrowave or other dedicated AC welder and weld aluminum to your heart's content.  They have more capability in AC because that is a whole weld engineering subject unto itself.  This is one case where one size does not fit all.ScottMiller XMT 350 CC/CV w/gas solenoid opt.Miller S-22A wirefeederBernard 400A "Q" gunMiller Spoolmatic 30A / WC-24C-K 200A torch/gas lensWeldcraft WC-18 watercooled torchHypertherm Powermax 30Victor O/A
Reply:Now I understand this issue, I dont know that AC is associated the High frequency generation, thanks for your replyMauricio
Reply:My maxstar 200DX is DC only and it has high frequency start.  It does have pulse as well but even the SD models have HF start.As for machines like the xmt, external high frequency modules can be added.  The HF modules from miller are pretty expensive new but can be had for a song used (very limited market).Con Fuse!Miller Dynasty 350Millermatic 350P-Spoolmatic 30AMiller Multimatic 200Hypertherm PowerMax 1000G3Miller Maxstar 200DX
Reply:Your maxstar is not a multi process welder. The xmt's are a fine multiprocess machines but they do not have built in wire feeders and cost is very high.JasonLincoln Idealarc 250 stick/tigThermal Dynamics Cutmaster 52Miller Bobcat 250Torchmate CNC tableThermal Arc Hefty 2Ironworkers Local 720
Reply:It is possible to add a High Frequency box to an  Inverterc V-350 from Lincoln.But I was talking about a multiprocess machine with a GTAW High frequency Start built in...Mauricio
