6.0 Maintenance.

Apart from carbon electrode replacement, the SR80 contains no user serviceable parts. In the event of
failure, please return the welder, carefully packed, to the distributor from which it was purchased who
will arrange for the necessary repair.

6.1 Carbon Electrode Replacement.

After considerable use, the carbon electrode will need attention. The carbon may be trimmed in a drill
or lathe chuck using a metal file to give an included angle of about 30° with the tip approx. 2mm dia.
To remove the carbon electrode, slide off the viewing filter, slacken the grub screw on the underside
of the argon shield (2mm Allen key provided) and pull off the shield. Slacken the grub screw on the
right-hand side of the electrode holder and withdraw the electrode. When fitting a new or trimmed
electrode, insert it loosely and offer up the argon shield to the front panel at the side of the electrode
holder and, using a straight edge, push the electrode in until it lines up with the front face of the shield.
Tighten the grub screw, replace the argon shield and viewing filter.
