11. c Set TENSION indicator pin to center of scale Turning the tension adjustment knob varies the initial tension on the movable clamp The initial spring tension determines the pressure that will be applied between the saw blade ends during the welding process More tension is required for wide blades To adjust the settings for each width of blade perform several experimental welds setting the tension at different points When the settings for the best widths have been selected make a note of it for future reference Wood cutting band saw blades are usually made of lighter gauge and softer steel than those used for metal cutting Therefore the welding characteristics are different requiring less tension Blades and clamp Jaws must be free of oil and chips for best results d The POWER ADJUSTMENT SWITCH is for the purpose of reducing the output of the welder when narrow blades are welded It is factory calibrated to the Down position for 1 8 to 3 8 width blades The Up position is for blades 3 8 to 3 4 in width e Place weld handle in vertical position f Holding both clamp handles in a vertical position insert the blade ends one at a time into the jaws with blade teeth against the back of guide Center the ends in the space between the jaws so ends just touch each other Clamp the Jaws with clamp handles Adjust jaw opening if necessary by turning the jaw adjusting screws in or out When correctly adjusted the clamp handles wi
