Semi automatic sheet metal welding machine - with electrode wire tensioning devices |
摘要 |
<p>In the welding machine described in the parent patent a pneumatically actuated piston is used for tensioning the electrode wire after its passage over the second electrode roller. This accommodates the elongation the wire formed as a result of the pressure and consequent deformation when pressed against the sheet metal workpieces.</p> |
