As Fig. 1, shown in Figure 2, parts of the present utility model consist of: handle grip (1), moving handle (2), housing (3), weldment box (4), weld line bearing frame (5) (16) road wheel (7), wheel shaft (8), welding support (9), bonding cable (10), welding resistance dop (11), bonding clamp (12), welding resistance power supply indicator (13), welding resistance and receipts fiery selector switch (14) are received ignition source indicator lamp (15), welding resistance time control knob (17), welding resistance time control indicator lamp (18), standing screw (23), welding resistance press button (24), electrode holder cover (25), time control circuit printing plate (26), A.C. contactor (27), welding transformer (28), time control circuit transformer (31).Among Fig. 1, (6) are the ground strap outlet, and (20) export line for welding resistance, and (29) draw the end of a thread for the primary winding among Fig. 2, and (30) and (32) draw the end of a thread for the transformer secondary output winding.
Bonding clamp shown in Figure 3 comprises clamp up knob (33), stage clip (34), and steady pin (35), handle (38) under upper and lower jaw (36) (37), the clamp, ground connection is clamped iron plate realization by jaw (36) (37).
Packing ring stretcher shown in Figure 4 comprises handle (38), weight upper limit card (39), weight sliding bar (40), weight (41), weight lower limit card (42) and packing ring drag hook (43).
Electrode holder shown in Figure 5 is except that the part of Fig. 1, and (44) are the cable fixing hole, and (45) are welding resistance dop jack.
Receipts fire shown in Figure 6 is used to receive fiery shaping process with carbon stick.
As shown in Figure 7, the welding resistance dop is spherical dop, and the gasket groove of dress packing ring and the plug (48) that matches with jack (45) are arranged on the dop.
After body of a motor car is damaged, the position coating removal polishing of will caving in, bonding clamp (12) shim plate earthing nearby, be placed on packing ring in the groove of welding resistance dop (11) this moment, and putting forth one's strength is placed in recess with packing ring, Push switch (24), connect power supply, the very fast molten recess that is implanted in of packing ring.Stretcher drag hook (43) is hooked packing ring, hold handle (38) and stretch repeatedly, weight (41) slides up and down repeatedly along sliding bar (40), and recess is evened up.Beat gently from the packing ring outside with hand hammer, packing ring is come off.
When needs are received fiery shaping, change the welding resistance dop, carbon stick to be changed, selector switch (14) is removed to receiving fiery position, and the fire place is received in the carbon stick contact, needs the shaping local pyrexia to receive fire, reaches the shaping purpose.
