Note: Although point gap adjustment is considered to be part of regular mainte-

nance, and is not an item covered under warranty, the following adjustment pro-

cess is provided for experienced users only. If you suspect you have a a problem

with the point gap due to hard starting of the arc, contact Everlast Tech Support

before proceeding with point gap adjustment for proper diagnosis and a more de-

tailed adjustment procedure.

To open the unit to adjust the point gap :

Unplug the welder. Wait 30 minutes to allow capacitors to discharge to pre-

vent possible shock and injury. WARNING: If possible, do not touch unrelat-

ed circuits and components, especially capacitors, during this adjustment

process to reduce the chance of possible shock and injury.

2) Remove the Rear plastic cover by removing screws with a small screw driver,

remembering to remove screws holding the cover that are located on the bot-

tom. There is no need to remove the front cover.

3) Remove screws in metal cover. Gently spread the bottom of the cover with

your fingers about 1" on either side. Simultaneously slide the metal cover to-

ward the rear and pull up to remove the cover from the chassis.

4) Locate the HF board located toward the front of the unit. This board is mount-

ed under the top metal pan and the points should be visible from the left side

(side determined by facing the front of the unit). The points will have two car-

bon contacts hanging under the bottom of the metal pan. These will be held in

place by two brass nuts that are used to lock the contacts in place. Check the

point gap with either a feeler gauge by sliding it between the points. Access

may be tight, but try several angles to get the feeler gauge in between the

points. The gap should be set to anywhere between .029'and .045", with .030"

to .035" being preferred.

5) If adjustment is needed, loosen the locking nuts slightly so that the end of the

brass contact holder can be rotated with a small flat bladed screw driver. Slow-

ly adjust the points until slight contact is made with the feeler gauge. When

completed hold the contact in place with the screw driver while the locknut is

retightened, making sure the contact holder does not rotate in the process.

6) Recheck the point gap. Make any necessary re -adjustments. Reassemble the

unit.
