text 0 1 289 110 STEP 4 Warm up the work piece using no torch motion. Torch motion in steel welding is to dissipate the heat over a larger area. Aluminum, because of its highly heat-conductive nature, dissi- pates the heat too much! Keep the flame very close to the work. Get some flux on the work by momentarily bringing the welding rod into the flame. ~ text 326 8 615 108 STEP 5 Unless you are very experienced, you will not see the slight change that occurs as the alum- inum liquifies. The tuned eye sees a slight depression in the surface, possibly a matte skin covering a glossiness under- neath. Liquification occurs slightly after the flux liquifies or spreads out. ~ line 172 132 172 129 line 172 129 176 127 line 176 126 182 123 line 182 123 189 122 line 189 122 198 122 line 198 122 203 124 line 203 124 208 127 line 208 127 236 127 line 236 127 274 129 line 274 129 299 135 line 299 135 391 140 line 391 140 452 150 line 452 150 467 155 line 467 155 472 162 line 472 162 472 171 line 472 171 472 178 line 472 178 458 182 line 458 182 278 182 line 278 182 273 184 line 273 184 267 187 line 267 187 251 187 line 251 187 240 184 line 240 184 236 182 line 237 182 227 180 line 227 180 201 180 line 201 180 148 180 line 148 180 133 177 line 133 177 124 174 line 124 174 117 167 line 117 167 114 162 line 114 162 113 156 line 114 156 119 149 line 119 149 123 145 line 123 145 130 143 line 130 143 139 141 line 139 141 150 140 line 150 140 160 140 line 161 140 165 140 line 165 140 170 139 line 170 139 173 133 bigtext C 2 338 168 Honda line 375 145 391 141 line 391 141 400 138 line 401 138 409 136 line 409 136 433 138 line 433 138 476 148 line 476 148 546 164 line 377 145 384 148 line 384 148 397 144 line 397 144 411 143 line 411 143 419 143 line 419 143 538 171 line 531 173 548 162 line 548 162 579 167 line 532 173 561 182 fatbit 406 142 0 405 142 0 404 142 0 403 142 0 402 142 0 401 142 0 400 141 0 399 141 0 398 141 0 397 141 0 396 141 0 395 141 0 414 137 1 413 137 1 412 137 1 411 137 1 410 137 1 409 137 1 408 137 1 407 137 1 414 136 0 413 136 0 412 136 0 411 136 0 410 136 0 409 136 0 408 136 0 407 136 0 line 378 145 369 150 line 369 150 381 147 fatbit 374 148 1 376 147 1 377 147 1 378 147 1 378 146 1 381 147 1 380 148 1 379 148 1 375 149 1 371 150 1 line 343 150 348 150 line 348 150 354 151 line 354 151 357 152 fatbit 359 154 1 351 156 1 350 156 1 349 157 1 351 154 1 349 154 1 348 154 1 345 152 1 345 153 1 344 153 1 343 153 1 346 157 1 348 157 1 349 157 0 341 156 1 340 156 1 339 156 1 345 155 1 340 152 1 338 152 1 340 155 1 339 155 1 338 155 1 336 155 1 331 155 1 331 156 1 330 156 1 337 158 1 336 158 1 text 488 124 616 146 Aluminum is molten under~ text 487 142 621 152 surface skin.~ circle 258 179 9 circle 190 130 10 linestyle 3 circle 152 145 3 circle 129 151 3 circle 130 168 3 circle 184 174 3 circle 266 135 3 circle 324 141 3 circle 387 176 3 circle 448 177 3 circle 443 154 3 circle 212 133 3 linestyle 1 changepattern 11 flood 262 161 line 476 126 351 126 line 351 126 350 145 line 350 145 339 141 line 349 146 358 140
