HINTS
FOR EASY BOREWELDING
-
Use a good quality wire with a large
"cast". Check cast by pulling off 5 or 6 feet of wire, drop it on a hard
floor, and measure the resulting diameter. If it is 48" or greater, you
have a desirable cast wire...if diameter is under 48" you may experience
slight weld bead instability. TRY OUR NEW 70S6 SOLID
ULTRA LARGE CAST WIRE AVAILABLE IN .030" and .035".

order part no. 1103, for .035" order part no. 1202
-
For steel welding we recommend a gas
shield mixture of Argon and CO2. Percentage of Argon minimum:75%,
maximum: 92% flowrate varies but indoors generally 25--30 cfh is sufficient.
Outdoor welding may require that you cap the end of your bore with tin
foil, this will help contain shielding gas if windy.
-
Use a power supply that allows voltage
adjustment while you are welding. Click-type voltage adjusters do not allow
fine adjustment once your bore welder has started.
-
For skip welds or bores where you only
need to build up a portion of the bore, we recommend hooking your BOA up
to a wirefeeder that has a burnback control installed.
-
Set torch nozzle stick-out at about
1/8" from workpiece bore.
-
Use proper torch rotation speed. Measure
bore you will be welding in and refer to chart on borewelder for approximate
speed setting. To vary buildup thickness you may adjust rotation
speed and/or wire feed rate.
