BLADE GUIDE ALIGNMENT
There are two types of alignment systems available for the FW-200 welder, Back Edge and Tooth Edge. The Tooth Edge system
can be obstructive when loading and unloading blades and is more difficult to calibrate than the Back Edge system, but once calibrated
the guides are simply rotated from one setting to the next for different width blades. The Back Edge system does not obstruct loading
and unloading and is much easier to re-calibrate, but requires re-calibrating whenever changing blade widths.
NOTE:
All blade-stock has a curve in the back edge known as “camber”. If the camber is too severe, using Back Edge guides that are
setup straight may cause blade misalignment. However, this is not a problem for most material.
BACK EDGE GUIDE CALIBRATION
1) Mount the calibration guides to the front of the carriages, making sure the mating surfaces are clean and smooth, and rotate
them to a setting sufficient for the desired blade’s tooth size. (Note: Make sure the front of the lower jaws do not interfere
with the calibration guides as this will cause them to not sit flush against the front of the carriage.)
2) Loosen all four guides and slide them all the way to the back.
3) Insert a blade of the desired size into the jaws, pull it against the calibration guides, and clamp it in place.
4) Slide the two inside guides against the back of the blade and tighten them in place.
5) Remove the calibration guides and the blade from the machine and set them aside.
6) Insert a 1/16”-1/8” thick x 24” long steel straightedge into the jaws, push it against the inside guides, and clamp it in place.
7) Pull the outside guides against the straightedge and tighten them in place.
8) Unclamp and remove the straightedge from the machine.
TOOTH EDGE GUIDE CALIBRATION
1) Mount the inner guides to the front of the carriages, making sure the mating surfaces are clean and smooth, and rotate them to
setting #4. (Note: Make sure the front of the lower jaws do not interfere with the blade guides as this will cause them to not
sit flush against the front of the carriage.)
2) Rotate the outer guides to setting #4.
3) Load a 1/16”-1/8” thick x 24” long steel straight-edge into the jaws, pull it against the INNER guides mounted to the front of
the carriages, and clamp it in place.
4) The straightedge should be touching all four guides, and be able to be raised and lowered without hanging on the top of the
outer guides. (Proceed to step 10 if the outer guides are aligned.)
5) Loosen the mount screw on the bottom of the guide mount to be adjusted.
6) Slide the guide mount so that the blade guide is touching the straightedge.
7) Tighten the mount screw and recheck the alignment of the blade guide as described in step 4.
8) Repeat steps 5-7, if necessary, until alignment is achieved.
9) Repeat steps 5-8, if necessary, for the remaining outer guide.
10) Unclamp the straightedge, remove the inner guides from the carriages and mount them to the inner guide mounts, then rotate
them to setting #4.
11) Load the straightedge into the jaws, pull it against the OUTER guides, and clamp it in place.
12) The straightedge should be touching all four guides. (Proceed to step 15 if the inner guides are aligned.)
13) Perform steps 5-8.
14) Repeat step 13, if necessary, for the remaining inner guide.
15)
Unclamp and remove the straightedge from the jaws.
