WARNING
Orbital gas tungsten arc welding (GTAW) can be
hazardous. Only qualified persons should use this equipment.
After welding, the work piece, weld head, electrode,
fixture block, and collets can be extremely hot and may cause burns.
Keep children away.
Pacemaker wearers should consult with their
physician before operating this equipment.
Read and understand ANSI Standard Z49.1, “Safety
in Welding and Cutting,” from the American Welding Society and OSHA Safety and Health Standards, 29 CFR 1910 and 1926, from the U.S. Government Printing Office.
The M200 power supply has no internal serviceable
parts and should not be disassembled. Return the M200 power supply to an authorized Swagelok sales and service representative for service.
ELECTRIC SHOCK can kill.
Touching live electrical parts and failure to operate
equipment properly can cause fatal electric shock and severe burns. Incorrectly installed or improperly grounded equipment is a hazard. To avoid injury:
Do not touch live electrical parts.
Keep all panels and covers securely in place. Do not
touch electrode connector, electrode, or rotor after pressing start. The electrode is electrically charged during the weld process.
Follow local electrical codes and the guidelines in this manual when installing the M200 power supply. Shock hazards can exist even when equipment is properly installed, so it is important that the operator be trained in the proper use of the equipment and follow established safety practices.
Frequently inspect input power cord for damage or bare wiring—replace immediately if damaged.
Properly unplug the power cord. Grasp the plug to remove it from the receptacle.
Page 7
FUMES AND GASES can be hazardous.
Welding produces fumes and gases. Breathing these
fumes and gases may be hazardous to your health. Build-up of gases can displace oxygen and cause injury or death. To avoid injury:
Do not breathe fumes or gases.
Ventilate the area and/or use exhaust at the arc to
remove welding fumes and gases.
When welding materials that produce toxic fumes, such as galvanized steel, lead, cadmium-plated steel or other coated metals (unless the coating is removed from the weld area), or any other welding material, keep exposure below threshold limit values (TLV), permissible exposure limits (PEL), or other applicable health and safety limitation. If necessary, wear a respirator. Read and understand the Material Safety Data Sheets (MSDS) and follow the manufacturer’s instructions for metals, consumables, coatings, cleaners, degreasers, or any other substance that may be present during the weld process.
Do not work in a conned space unless it is well ventilated or you are wearing an air-supplied respirator. Always have a trained watch-person nearby. Welding fumes and gases can displace air and lower the oxygen level causing injury or death. Be sure the breathing air is safe.
Do not weld in locations near degreasing, cleaning, or spraying operations. The heat and rays of the arc can react with vapors to form highly toxic and irritating gases.
The ultraviolet light emitted by the welding arc acts on the oxygen in the surrounding atmosphere to produce ozone. Test results➀, based upon present sampling methods, indicate the average concentration of ozone generated in GTAW process does not constitute a hazard under conditions of good ventilation and welding practice.
Shut off gas supply when not in use.

ARC RAYS can burn eyes.
Arc rays from the welding process produce intense
visible and invisible (ultraviolet and infrared) rays that can burn eyes. The M200 power supply is meant for use only with enclosed Swagelok weld heads, which minimize exposure to these harmful rays. To avoid injury:
Do not look at welding arc.
Use protective screens or barriers to protect others
from ash and glare; warn others not to watch the arc.
Wear personal protective equipment, including eye protection.
WELDING can cause fire or explosion.
Welding on closed containers, such as tanks, drums, or
pipes, can cause them to explode. The hot work piece and hot equipment can cause res and burns. Ensure the area is free of combustibles before welding. To avoid injury:
Do not place the M200 power supply over a combustible surface. See the label on the bottom of the M200 power supply (Fig. 1).
Do not weld in a combustible environment.
Watch for re, and keep a re extinguisher nearby.
Do not weld on closed containers such as tanks,
drums, or pipes, unless they are properly prepared in accordance with AWS F4.1.
Do not use the M200 power supply to thaw frozen pipes.
Do not use extension cords that are in poor physical condition or have insufcient current capacity. Failure to do so can pose re and shock hazards.
Sparks and spatter are thrown from the weld arc. The M200 power supply is meant for use with enclosed weld heads, which minimizes exposure to spatter. Wear proper protective equipment, including eye protection.

Setting Up the Gas Supply System
The M200 power supply has an integral mass ow controller (MFC) to control and monitor the ow of the gas supply system that provides OD shield gas to the weld head. OD shield gas lls the weld chamber to protect the electrode and weld puddle from contaminating elements in the surrounding air.
ID purge gas ows within a tube or at the back of a weld joint to remove oxygen and prevent oxidation.
Typical OD Shield / ID Purge Gas Supply System
Figure 9 shows a typical gas supply system. Before setting up the gas supply system, read and understand the Safety section of this manual. See page 5.
1. Make sure the gas storage containers are upright and secured before use.
2. Check all connections for leaks.
3. Use only Swagelok quick-connect stems (ordering number SS-QC4-S-400) as gas connectors on the M200 power supply.
4. Regulate the OD shield gas pressure to obtain the desired ow rate. The typical pressure range is 45 to 50 psig (3.1 to
3.4 bar). Flow rates greater than 70 std ft3/h (33 std L/min) may require higher pressures.
M200 Power Supply User’s Manual 21
CAUTION
Do not mix or interchange parts with those of other manufacturers. Personal injury or equipment damage can result.
NOTICE Do not exceed an inlet pressure of 100 psig (6.8 bar) or MFC can be damaged.
NOTICE The MFC is not a shutoff device. There may be gas flow of up to 1/2 std ft (0.24 std L/min) when the shield gas is off.

Limits /
Tolerances
(Fig. 25)
Limits
Limits are used to restrict the amount of adjustment a user with a security password can make without entering a programmer or owner password.
Limits from 0 to 100 % are set at the programmer and owner levels. Current and Purge Limits are represented as a percentage of the weld procedure values.
Example: if the Average Amps for Level 1 is 100 A and the current limit is 50 %, the M200 power supply will not allow an adjustment of Average Amps above 150 A or below 50 A. The factory default for limits is 100 %.
Average Amps can be adjusted within the limits on the lower section Levels tab using the up and down buttons.
See Adjusting Average Amps, page 31, for more information.
Purge parameters can be adjusted within the limits on the Purge Setup tab.
Tolerances
The Weld Log records out-of-range values for Average Amps, Average Speed, and OD Shield Flow in the Weld Log, based on tolerances set. Tolerances are adjustable at the programmer and owner levels, as a percentage of the base value.
Current and speed tolerances are adjustable up to 9.9 %. The factory default for new weld procedures is 2.5 %.
Purge tolerance is adjustable up to 100 %. The factory default is 15 %.
Example: if the Average Amps for Level 1 is 100 A and the current tolerance is 5 %, the M200 power supply will return a current tolerance error at the end of the weld if the Average Amps is below 95 A or exceeds 105 A.
Current tolerance. If the Average Amps tolerance is exceeded during the weld, a current tolerance error will be recorded.
Speed tolerance. If the average speed is outside of the average speed tolerance at the end of the weld, a speed tolerance error will be recorded.
Purge tolerance. Purge tolerance is represented by the yellow band in the shield gas flow meter displayed on the process tab. If the OD shield flow is outside of the tolerance, the shield gas bar flow meter display will turn red. If there is no OD shield gas present during prepurge, the M200 power supply will not proceed. If the OD shield gas flow drops below 8 std ft
3
/h (3.8 std L/min) during a weld, the M200 power supply will stop welding to prevent possible damage to the weld head.

Operation
(Fig. 42)
Specifies the frequency of the Weld Log printout. When set to zero, the printer prints out a Weld Log only when the Print button is pressed. Setting Auto Print Count to any other number defines the interval at which Weld Logs are printed: set to 1, the printer prints after every weld; set to 10, the printer prints after every 10th weld, etc.
Allows the user to set some of the M200 power supply functions:
Jog Speed %: Enables the user to set the speed of the weld head when jogging as a percentage of the weld head full speed. See the weld head user’s manual for the full speed ratings of individual weld heads.
Electrode Touch Volts: This is the voltage setting used to detect if the electrode touches the weld puddle. The factory setting of 4 V should not be adjusted without testing, but may have to be raised when using longer weld head extension cables. Raising the voltage makes the M200 power supply more sensitive and can cause it to record an electrode touch when there was none and generate an error code. Lowering the voltage can allow an electrode touch without generating an error code.
Fan Power-On State: The default setting for the fan power-on state is
on. The first time the M200 power
supply is powered on, the fan button on the Main screen will blink and the fan will be in the continuous run state. Changing the Fan Power-On state to
off
will make the default for the fan button on the main screen
off. The user can not disable the fan during
the weld cycle. The fan is always on during the weld cycle.

Weld Parameter Development
Weld parameters are the values used to create a weld procedure. The shape and duration of the output current waveform—a graphical representation of the weld procedure— is determined by the weld parameter settings. Figure 56 shows the waveform typical parameters generate during the course of a multilevel weld. The weld parameter settings are:
Parameter 1 2 3 4
High Amps, A 71.7 68.1 64.5 60.9
Low Amps, A 21.7 21.7 21.7 21.7
Weld Time, s 5.0 5.0 5.0 5.0
Ramp Time, s 0.0 0.0 0.0 0.0
Pulse Rate, Hz 4.0 4.0 4.0 4.0
High Amps Width, % 28.0 28.0 28.0 28.0
High Amps Speed, rpm 3.5 3.5 3.5 3.5
Low Amps Speed, rpm 3.5 3.5 3.5 3.5
Average Amps, A 35.7 34.7 33.7 32.7
During a typical weld, the M200 power supply pulses between High Amps and Low Amps. In this case, the current pulses between the high and the low levels four times per second. The current is at the high level 28 % of the time and at the low level 72 % of the time.

Weld Parameter Changes
High Amps, High Amps Width, and Rotor Speed affect the depth of penetration of the weld. The control of these parameters allows ne tuning of the weld penetration level.
Creating a Weld Procedure Guideline
A Weld Procedure Guideline is the initial set of weld parameters used to program the M200 power supply for a specic weld job. The M200 power supply Auto Create feature is recommended to generate the weld procedure, but for instances where the work piece dimensions are not available in the M200 power supply dropdown boxes or manual program creation is desired, the Weld Procedure Guideline Worksheets starting on page 54 can be used to determine work specications and calculate weld parameters.
Butt Welds
The Butt Weld Procedure Guideline Worksheets can be used to generate procedure guidelines for butt-to-butt tube and pipe welds, as well as other cylindrical butt-to-butt welds.
The worksheets (fractional, page 54; metric, page 58) go through the steps required to create a Weld Procedure Guideline. Alongside each step is an example to show how an actual parameter value would be created. Both examples are based on 316L tube-to-tube fusion butt welds. The example fractional tube size is 1/2 in. OD and 0.049 in. wall thickness. The example metric tube size is 12.0 mm OD and 1.0 mm wall thickness.
M200 Power Supply User’s Manual 53
Note: Any procedure generated manually
using the Weld Procedure Guideline Worksheets or generated automatically by the M200 power supply is only a guideline. The final weld quality depends on the operator’s welding experience and on the proper use of welding techniques. Parameter adjustments will need to be made and weld quality verified in accordance with the user’s quality standards.

This step, in conjunction with rounding the Weld Time to the nearest 0.5 second, prevents consecutive periods of low
amperage output during the transition from one level to the next. This would be observed as skipping between weld levels. Note from Fig. 56, page 52, each level begins with the Low Amps period of the pulse cycle. The Weld Time
multiplied by the Pulse Rate: Weld Time  Pulse Rate, that is, the number of seconds per level  cycles per second must equal a whole number of cycles per level to ensure each level ends with a complete Low to High Amps cycle

Automatic Tube (ATW) and Socket Welds
In addition to tube butt welds, the Weld Procedure Guideline Worksheets can be used to generate procedure guidelines for
automatic tube welds (ATW) and socket welds. These weld joints have features that require some weld parameter values to be different from tube-to-tube butt welds.
ATW Welds
Because the ATW cuff adds material to the weld joint, the wall thickness used for current calculations must be increased to compensate for the additional heat needed. In these cases it is common to add 40 % of the ATW cuff thickness to the tting wall thickness (Fig. 57).
The M200 power supply Auto Create feature calculates this automatically. The worksheets include this step.

Socket Welds
All socket welds use a single-pass technique. The arc gap and electrode offset parameters are referenced from the socket. The arc gap is 0.010 in. (0.25 mm) from the socket OD for all sizes, and the offset is 0.015 in. (0.38 mm) from the socket face (Fig. 58). Adjustments may be necessary.

Advanced Weld Procedure Techniques
The M200 power supply incorporates features that allow adjustments to weld procedures created with using Auto Create, Manual Create, and Single Level Mode programming. These features allow the programmer or owner to adjust the heat input by varying different weld procedure parameters. They also enable optimization with advanced features such as tacking and ramping.
Page 65
Tacks
Tacks are small welding points that do not penetrate the wall completely. They are used to hold the joint alignment and joint gap during welding.
The M200 power supply will allow up to 20 tacks in Auto Create or Manual Create (Fig. 59). See the Tack Parameter Guideline
Worksheet below, for use in conjunction with the Weld Procedure Guideline Worksheets. Where the two worksheets have common parameters, use the Tack Parameter Guideline Worksheet values.
If tacks break during welding:
Increase the time by 0.5 seconds for each tack. This will
increase the tack size.
Increase the number of tacks.
If tacks are not fully consumed by the weld, decrease the time by 0.5 seconds for each tack.
If the weld is to be completed at a later time, tacks must be brushed to remove oxidation before welding. Oxidation can cause weld bead meander if it is not removed. Brushing is not required if the weld is made immediately after tacking.

Ramp Time
Ramp time is time taken at the beginning of a level to allow a gradual amperage change from the arc start current (for the rst level) or the previous level’s Low and High Amps settings (for all other levels).
The heat input effect of ramping depends on the levels’ current settings directly before and after the ramp (see Fig. 60):
Ramping from higher current to lower will input more heat into the level by gradually decreasing the current until the Low Amps for the level has been attained.
Ramping from lower current to higher will slow the heat input into the level by gradually increasing the current until the High Amps for the level has been attained.
Ramp time may be from 0.1 seconds up to taking the entire Weld Time for the level.

Ramping Up in Level 1
Ramping in the rst level may be used to slow the startup of the weld to allow controlled heat application, which is required for some materials.
Two methods for gradually adding heat to the material in Level 1 are postponed penetration while welding and added rotor delay time before welding.
Postponed Penetration While Welding
This method adds heat while the rotor advances. This weld most likely will not penetrate until some point during this rst level. The overlap time must be increased to ensure an even ID bead width through the whole rst level.
See Fig. 61 and the Level 1 Ramp—Postponed Penetration

Added Rotor Delay Time Before Welding
This method adds heat before the rotor begins advancing. In this case, full penetration is required before the rotor can advance, but the heat input must be incremental.
See Fig. 62 and the Level 1 Ramp Added Rotor Delay Time Guideline Worksheet below, for use in conjunction with the Weld Procedure Guideline Worksheets. Where the two worksheets have common parameters, use the Level 1 Ramp Added Rotor Delay Time Guideline Worksheet values.
Level 1 becomes a Ramp-up time and Rotor Delay Level. The rst weld level will be Level 2. To adjust the penetration:
Increase the start penetration by increasing the Weld Time of Level 1 or by increasing the weld input current using Adjust from the Weld screen.
Decrease the start penetration by decreasing the weld input amperage using Adjust from the Weld screen.

Step Programs for Multilevel Weld Procedures
A Step Program can be used to rene the control of the weld heat input. A step program is most commonly used when welding thick-walled or larger-diameter tubing to obtain more control over the current or decrease rotor speed.
In a Step Program, the rotor speed is different between the High and Low Amps periods. Decreasing rotor speed increases heat input; increasing rotor speed decreases heat input. The rotor speed may vary from zero to the maximum rotor speed of the weld head being used.
Calculations for Weld Time change signicantly for a Step Program. Use the following Step Program Parameter Guideline Worksheets to generate the necessary M200 power supply plug-in values.
The example fractional tube size is 2.0 in. OD and 0.109 in. wall thickness.
The example metric tube size is 54.0 mm OD and 2.6 mm wall thickness.

This step, in conjunction with rounding the Weld Time to the nearest 0.5 second, prevents consecutive periods of low
amperage output during the transition from one level to the next. This would be observed as skipping between weld levels. Note from Fig. 56, page 52, each level begins with the Low Amps period of the pulse cycle. The Weld Time
multiplied by the Pulse Rate: Weld Time  Pulse Rate, that is, the number of seconds per level  cycles per second must equal a whole number of cycles per level to ensure each level ends with a complete Low to High Amps cycle
before beginning the next level.

Single Level Mode Operation
In Single Level Mode, single level weld procedure guidelines developed on previous power supplies can be entered using the M200 power supply touch screen. Single Level Mode operation enables the user to enter either single pass or multiple pass weld procedure guidelines. Single Level procedures can be entered manually or by using the Program > Auto Create screen and choosing Levels Only in the Levels/Tacks eld, 1-Level in the Procedure Type eld, and Active (No-Save) in the Save Procedure eld.
Single Level Mode incorporates features of the M200 power supply including the internal mass ow controller, electrode position indicator, Electrode Change button, and the Weld Log.
The touch screen displays the welding process and message information. Messages indicate weld parameter setup errors, power supply status, etc. The status indicator lights on the touch screen show the welding process sequence.
The status indicator lights on the touch screen show the welding process sequence or ash if the power supply detects that a weld parameter is set incorrectly.
Single Level Current-Control Group
The current-control group determines the characteristics of the current output of the power supply during the weld process. The controls (Fig. 63) function as follows:
High Amps sets the maximum current output used during the weld process. This setting affects the depth of penetration of the weld.
Low Amps sets the minimum current output used during the weld process. This is the current level required to maintain the arc and provide enough background heat to maintain the weld puddle.
SINGLE LEVEL MODE OPERATION
Pulse Rate sets the number of pulses per second between the High Amps and Low Amps current levels during the weld process.
Amps Width sets the percentage of time the current is at the High Amps level for each High Amps / Low Amps cycle.
Delay Current sets the current during the Delay Time. This current level helps stabilize the initiated arc and develops the weld puddle.
Fig. 63— Single Level Current-Control
Group
Page 85
Single Level Timing-Control Group
The timing-control group determines the weld process timing. The controls (Fig. 64) function as follows:
Delay Time is the time in seconds between the arc start period and rotor movement.
The current specied for the Delay Current is maintained
during this time.
The rotor does not move during this time.
Prepurge is the time in seconds when OD shield gas ows through the weld head and around the weld joint before the arc is initiated.
Note: A minimum of 10 seconds prepurge is recommended for all Swagelok weld heads. If weld head extension cables are used, add one second for each foot of extension cable.
Weld Time is the actual welding time in seconds at the average current. During the Weld Time, the output current cycles between High Amps and Low Amps at the Pulse Rate and High Amps Width entered.
During this time, the rotor moves at the speed specied as
the Rotor Speed.
Weld Time process forms the main body of the weld.
Downslope is the time in seconds during which the average weld current decreases uniformly until the arc is extinguished.
During this time, the rotor continues to move at the speed
specied as the Rotor Speed.
Downslope reduces the likelihood of weld cracking.
Postpurge is the time in seconds the OD shield gas continues to ow through the weld head and around the weld joint after the arc is extinguished. This gas ow prevents oxidation and contamination of the weld bead and electrode while the work piece is cooling.
Rotor Speed is expressed as a percentage of the maximum revolutions per minute (rpm) that the rotor can attain. A rotor speed setting of 99 gives the maximum rpm for the weld head.

Single Level Status Indicator Lights
The status indicator lights (Fig. 67) monitor certain elements of M200 power supply operation.
The conditions monitored by some of the indicators are independent of the welding process. Most of the indicators light during the welding process to show the control sequence executed by the M200 power supply. The control sequence is affected by the values entered into the timing-control group.
Weld Head indicates the weld head is connected.
PrePurge indicates the prepurge cycle is in progress.
Start indicates the power supply is in the arc start portion of
the weld cycle.
Weld Time indicates the weld process is in progress.
Downslope indicates the downslope cycle is in progress.
PostPurge indicates the postpurge cycle is in progress. OD
shield gas continues to ow to the weld head, and the rotor moves to the home position.
Rotor indicates the rotor is in motion.
The display (Fig. 67) monitors system operation during welding and provides message information. The display functions are:
Average Current indicates the average arc current measured during the weld process.
Average Voltage indicates the average arc voltage measured during the weld process.

Single Level Weld Procedure Guidelines
These Single Level Weld Procedure Guidelines show suggested weld parameter settings based on:
Swagelok weld head used
weld joint type
material type
outside diameter and wall thickness of the weld joint.
These guidelines are for reference only; modications may be necessary to achieve the desired results.
Table Note
The Average Amps column lists a calculated value based on certain weld parameters. This value should approximate the value shown on the Average Current display during the weld process. Because it is a calculated value, some variation may be seen based on the welding conditions.
Note: The M200 power supply Auto
Create feature can be used to generate a one-level, multipass weld procedure.
Any procedure generated manually
using the Single Level Weld Procedure Guidelines or generated automatically by the M200 power supply is only a guideline. The final weld quality depends on the operator’s welding experience and on the proper use of welding techniques. Parameter adjustments will need to be made and weld quality verified in accordance with the user’s quality standards.

Evaluating Weld Quality
Identifying Proper Welds
Figure 68 illustrates an acceptable weld: continuous full penetration from the outside diameter (OD) to the inside diameter (ID); a crown on the OD; and minimal weld bead convexity on the ID.
To determine whether a weld is proper or improper:
1. Inspect the weld on the outside of the tube for:
Uniformity.
Cracks.
Undercuts.
Excessive oxide.
2. Inspect the weld on the inside of the tube for:
Uniformity, cracks, undercuts, and excessive oxidation.
Full penetration.
Excessive weld-bead width variations.
Excessive weld-puddle overlap.

Improper Welds
The following weld examples show how changes in weld parameters affect weld shape. The reference weld (Fig. 70 and
71) was made using a 316L stainless steel tube with a 1/2 in. OD and 0.049 in. wall thickness, in accordance with the weld parameter settings shown below:

Below are guidelines on what to look for when troubleshooting a weld that did not penetrate the ID; displayed too much ID convexity and weld bead width; or showed too much or too little weld-puddle overlap. To make adjustments to the parameters, check them against the Auto Create values and see Advanced Weld Procedure Techniques, page 64, for more tips on correcting an improper weld.

No ID Penetration
Lack of ID penetration can be caused by several improper weld procedure settings.
All of the examples shown below result from decreased arc intensity and—consequently—heat input, resulting in no ID penetration.
High Amps Width Too Short (Fig. 72)
High Amps Width setting changed from 28 to 24 %.
This lowers the Average Amps from 35.7 to 33.7 A.
High Amps Current Too Low (Fig. 73)
High Amps setting changed from 71.7 to 55.4 A.
This lowers the Average Amps from 35.7 to 34.1 A.
Low Amps Current Too Low (Fig. 74)
Low Amps setting changed from 21.7 to 14.8 A.
This lowers the Average Amps from 35.7 to 30.7 A.
Rotor Speed Too High (Fig. 75)
Rotor speed changed from 3.5 to 4 rpm.
This lowers the average heat input per unit of time. Although the Average Amps for the weld is unchanged, Weld Time is decreased by 12.5 % and the heat input is decreased by 12.5 %.

Increased ID Convexity and Weld Bead Width
Increased ID convexity and weld bead width can be caused by several improper weld procedure settings.
All of the examples shown below result from increased arc intensity and, consequently, heat input, resulting in increased ID convexity and weld bead width.
High Amps Width Too Long (Fig. 76)
High Amps Width setting changed from 28 to 33 %.
This raises the Average Amps from 35.7 to 38.1 A.
Fig. 76—High Amps Width Too Long
High Amps Current Too High (Fig. 77)
High Amps setting changed from 71.7 to 80.6 A.
This raises the Average Amps from 35.7 to 38.2 A.
Low Amps Current Too High (Fig. 78)
Low Amps setting changed from 21.7 to 25.2 A.
This raises the Average Amps from 35.7 to 38.2 A.
Rotor Speed Too Low (Fig. 79)
Rotor speed changed from 3.5 to 2 rpm.
This increases the average heat input per unit of time. Although the Average Amps for the weld is unchanged, Weld Time is increased by 75 % and the heat input is increased by 75 %.
Weld-Puddle Overlap
The pulse rate should be set so that each weld puddle overlaps the previous one by about 80 %, as shown in Fig. 71. Changing the pulse rate can affect weld-puddle overlap and cause inadequate weld penetration or weld distortion.
Fig. 77— High Amps Current Too High
Fig. 78—Low Amps Current Too High
Fig. 79—Rotor Speed Too Low
Not Enough Weld-Puddle Overlap (Fig. 80)
If the weld puddles do not overlap enough, the weld can lose full penetration in some areas. Increasing the pulse rate from 10 to 25 per second will increase weld-puddle overlap and ensure full penetration of the weld joint.
Too Much Weld-Puddle Overlap (Fig. 81)
If the weld puddles overlap too much, the weld puddle may become distorted around the perimeter. Decreasing the pulse rate from 10 to 5 per second will decrease weld-puddle overlap and provide a more uniform appearance around the edges of the weld.

The rated output of the M200 power supply is available when connected to a 230 V / 20 A branch circuit. When connected to a branch circuit with a lower voltage, lower welding current and duty cycle must be used. An output guide is provided below. The values are approximate and must be adjusted downward if the fuse or circuit breaker trips off. Other loads on the circuit and fuse/circuit breaker characteristics will affect the available output. Do not exceed these welding conditions:
