text 7 1 282 13 PRACTICE #2, TORCH MOTION~ text 5 11 319 138 Repeat practice #1, but this time as you are heating the steel tube, move the flame in continuous little circles of about 1/2" diameter. This is called torch motion and is used in almost all gas welding applications. You will see that the torch motion will allow you to have a bigger puddle and maintain it longer before it collapses. Not only does torch motion give better control of the puddle, but also allows the welder to see better, because the flame is not constantly obscuring the view of the work. ~ line 523 119 533 109 line 533 109 551 98 line 551 98 556 96 line 556 96 562 96 line 562 96 565 100 line 565 100 564 102 line 563 101 572 99 line 572 99 579 99 line 579 99 581 100 line 582 100 583 102 line 583 102 582 105 line 582 105 592 102 line 591 102 596 102 line 596 102 599 103 line 599 103 599 104 line 599 104 599 107 line 599 107 598 108 line 598 108 603 105 line 603 105 608 105 line 608 105 611 106 line 611 106 610 109 line 610 109 600 117 line 600 117 594 121 line 594 121 583 129 line 583 129 558 139 line 558 139 519 152 line 522 120 519 125 line 519 125 495 137 line 495 137 447 159 line 518 120 521 111 line 521 111 523 107 line 523 107 533 110 line 533 110 489 97 line 489 97 489 94 line 489 94 495 91 line 495 91 505 89 line 505 89 545 100 line 604 114 627 121 line 591 123 622 132 line 493 90 441 77 line 441 77 416 81 line 416 81 418 83 line 418 83 440 80 line 440 80 491 94 line 509 91 495 98 circle 624 118 14 circle 607 129 13 circle 415 83 17 fatbit 618 131 0 617 131 0 617 130 15 616 130 0 615 130 0 614 130 0 613 129 0 612 129 0 611 129 0 610 129 0 609 128 0 608 128 0 607 128 0 606 127 0 605 127 0 604 127 0 603 126 0 602 126 0 601 126 0 600 126 0 601 125 0 599 125 0 618 130 15 617 130 0 618 130 0 601 124 15 599 125 15 601 125 15 601 124 0 598 125 0 597 125 0 627 121 0 626 121 0 625 120 0 624 120 0 623 120 0 622 119 0 621 119 0 620 119 0 619 119 0 618 118 0 617 118 0 616 118 0 615 117 0 614 117 0 613 117 0 fatbit 428 86 15 427 86 15 426 87 15 427 86 0 425 87 15 426 87 0 425 87 0 397 81 15 396 80 15 395 79 15 400 81 15 402 80 15 401 80 15 402 80 0 401 80 0 402 80 15 401 81 15 403 80 15 402 80 0 401 81 0 402 81 15 402 80 15 402 81 0 404 79 15 405 79 15 404 79 0 401 80 15 402 80 0 403 80 0 401 80 0 401 81 15 402 80 15 403 80 15 405 79 0 404 80 15 405 79 15 400 81 0 402 80 0 405 79 0 405 80 15 403 80 0 402 81 15 403 81 15 399 82 15 400 82 15 401 81 0 406 80 15 398 83 0 398 84 0 428 86 0 432 86 15 433 86 15 433 87 15 434 87 15 433 87 0 434 87 0 433 87 15 434 87 15 433 87 0 434 87 0 433 87 15 434 87 15 429 86 15 427 86 15 425 86 15 426 87 15 425 87 15 426 87 0 425 86 0 425 87 0 425 86 15 426 86 15 429 85 15 430 85 15 429 86 0 428 85 15 424 86 15 432 84 0 432 83 0 399 85 0 427 78 0 426 78 0 432 82 0 430 80 0 KC 388 73 447 93 534 108 fatbit 593 117 0 592 117 0 590 116 0 589 116 0 588 116 0 591 116 0 593 114 0 592 113 0 591 113 0 590 113 0 589 113 0 590 113 15 589 113 15 590 113 0 589 113 0 590 113 15 589 113 15 590 113 0 589 113 0 590 113 15 588 112 0 587 112 0 586 112 0 585 112 0 584 112 0 590 113 0 583 113 0 582 113 0 581 113 0 580 113 0 579 113 0 578 113 0 587 115 0 586 115 0 585 115 0 584 115 0 583 115 0 582 116 0 581 116 0 580 116 0 579 116 0 578 116 0 577 116 0 576 116 0 577 116 15 576 116 15 574 117 0 573 117 0 572 117 0 571 117 0 570 117 0 569 117 0 568 117 0 577 116 0 576 116 0 575 116 0 577 114 0 576 114 0 575 114 0 574 114 0 573 114 0 572 114 0 571 115 0 570 115 0 569 115 0 568 115 0 567 115 0 566 115 0 567 118 0 566 118 0 565 118 0 564 118 0 563 118 15 563 117 0 563 118 0 565 116 0 564 116 0 563 116 0 562 116 0 571 113 15 572 113 15 573 113 15 573 114 15 574 114 15 575 115 15 576 115 15 fatbit 593 122 15 593 123 15 592 123 15 592 124 15 592 125 15 591 125 15 591 126 15 590 126 15 589 127 15 588 127 15 587 127 15 586 128 15 585 128 15 584 128 15 583 128 15 581 129 15 580 129 15 579 129 15 580 129 0 579 129 0 583 128 0 text 443 46 588 60 TORCH MOTION~
