7 Welder Set-up

The initial set-up of the Pro-Wedge is by far the most critical aspect for proper operation of the
welder. Proper set-up not only leads to quality welding results but also minimizes wear and tear
on the welder itself. Adjusting the welder too tight can result in excessive wear on drive-train
parts such as gears, chains, sprockets, etc.

Set-Up Preparation

The procedures described in the following sections cover the initial set-up required for
various mil thickness materials and tolerances. These adjustments must be made while the
wedge heater is at room temperature. Refer to Figures 1 through 7 on the following pages
while performing these procedures. Referring to Diagram 1, use the actual material you
intend to weld, or if this is not possible use material that is the same mil thickness, cut two
pieces approximately 4 inches wide by 18 inches long and three smaller pieces
approximately 1/2 inch wide by 6 inches long. These five pieces of material will be used
as "gauges" for setting three adjustments on the Pro-Wedge.
