Choosing an A.C./D.C. Stick Arc Welder
In this 1080P HD video, Moses Ludel discusses A.C. versus D.C. arc welding, niche welding requirements and when to use these two welding modes. See the series of HD video welding sessions and demonstrations—at 4WD Mechanix Magazine’s 4WD Mechanix Video Network!
There is a place for A.C.and D.C. welding modes. Moses Ludel discusses the equipment you need for quality arc/stick welding. For our tutorial session, the 4WD Mechanix shop uses the versatile HTP America 221 Invertig TIG/stick machine.
A simpler “buzz” box typically offers A.C. stick welding mode. Some machines offer A.C. and D.C. modes. The HTP America Invertig 221 is a versatile A.C. and D.C. inverter TIG machine with optional liquid cooled torch. The 221 (above) doubles as a professional grade stick welder. Peak A.C. and D.C. arc/stick amperage is 220, which is plenty for most welding chores.
As voltage and amperage setting drops, the duty cycle increases. In this video, Moses Ludel discusses the duty cycle rating for the HTP America’s 221 Invertig machine. Above, the 221 is set for stick (SMAW) D.C. arc welding mode and for 136 amps.
