Setting The Arc Gap - Swagelok Series 5 Bedienungsanleitung

Setting the Arc Gap

The proper arc gap setting facilitates control of the weld and
improves consistency. The following steps cover how to set the
arc gap.
The arc gap is set by using the arc gap gage provided with the
weld head. The gage is adjusted for the desired arc gap and
then installed in the rotor aperture. With the gage in place, the
electrode can be positioned with reasonable accuracy.
Setting the Arc Gap Gage
1. Measure the outside diameters of the work pieces being
welded using a caliper or micrometer. See Figure 8(A). The
M200 will calculate the arc gap gage setting when using the
Auto Create feature.
2. Refer to the tables on page 12 for your nominal OD. Find
the "actual" outside diameter nearest to your measurement.
3. Adjust the arc gap gage to match the setting from the tables
on page 8. See Figure 12 (B).
