'How-to' Welding Class: Setting Up an
A.C./D.C. Stick Arc Welder
In this HD video, we set up the stick arc
welder in both A.C. and D.C. modes. Learn various settings available and when they apply. Subsequent sessions will
help improve your stick welding skills. See the series of HD video welding sessions and demonstrations—at

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 can
double as a professional grade stick welder. Shown here are balance (left) and frequency (right)
In the HD video, the Invertig 221 settings help
illustrate the options for stick welding. See the video for details on settings, modes and polarity, important
to your success at stick arc welding.
Shown here are the
quickly adjustable amperage and voltage settings for stick mode welding on the Invertig 221. The dial can change
amperage in seconds over the full range of weld settings. Voltage changes follow the amperage
Invertig 221 in TIG mode
(at left) delivers professional grade results with far less electric
current draw! Workhorses like the HTP America 221 and earlier HTP Invertig
201 (right) can double as stick welders. They operate on 230V
single phase for U.S. electrical circuits. (Non-U.S. configurations are also possible.) At the
magazine's shop, we use a dedicated 60-amp circuit (paired 30-amp breakers) as our welder-only
power source. Wiring size exceeds code standards and requirements throughout this
Note: At the magazine's shop, we use a dedicated 60-amp circuit (paired

throughout this circuit."Out-of-wall" amperage draw for the Invertig 221 in 230V single phase
mode is 26 amps at a 220 amperage setting in TIG mode; 32 amps for a 200 amperage setting in stick mode.
"Buzz boxes" and other types of transformer welding equipment draw considerably more amperage at each current
setting. Inverter technology like these HTP machines has advanced our welding capability and saves
Caution: Breakers, plugs and wiring gauge must
exceed requirements for the maximum load draw by a safe margin. If you are not familiar with electrical work, get a
qualified professional to
